1.2 Precautions for use

When using the E1 series inverter, please pay attention to the following points：

1.2.1 Constant torque and low speed operation

When the inverter is running with a normal motor for a long period of low speed, the heat dissipation effect will
be deteriorated, which will affect the life of the motor. If you need low-speed constant torque for long-term
operation, you must use a dedicated inverter motor.

1.2.2 Confirmation of motor insulation

When applying the E1 series inverter, please confirm the insulation of the motor before using the motor to
prevent damage to the equipment. In addition, please check the insulation of the motor regularly when the
environment of the motor is bad, to ensure the safe operation of the system.

1.2.3 Negative torque load

For situations such as lifting the load, there is often a negative torque, and the inverter will trip if an overcurrent
or overvoltage fault occurs. In this case, the optional braking resistor should be considered.

1.2.4 Mechanical resonance point of the load device

The inverter may encounter the mechanical resonance point of the load device within a certain range of output
frequency, and must be avoided by setting the jump frequency.

7
1.2.5 Capacitance or varistor for improving power factor
Since the output voltage of the inverter is pulse wave type, if the output side is equipped with a capacitor with
improved power factor or a varistor for lightning protection, it will cause the inverter to trip or damage the device.
Be sure to remove it, and it is recommended not to be on the output side. Add switching devices such as air
switches and contactors, as shown in Figure 1-1.

(If the output of the inverter must be zero when the output side switch device is activated)

Figure 1-1 Do not Connect the capacitor at the output of the inverter

1.2.6 Derate at Basic frequency setting

When the fundamental frequency setting is lower than the rated frequency, please pay attention to the derating
of the motor to avoid overheating of the motor.

1.2.7 Operating at frequencies above 50Hz

If it is operated above 50 Hz, in addition to considering the vibration and noise of the motor, it is necessary to
ensure the speed range of the motor bearings and mechanical devices.

1.2.8 Electronic thermal protection value of the motor

When the adapter motor is selected, the inverter can thermally protect the motor. If the motor does not match
the rated capacity of the inverter, be sure to adjust the protection value or take other protective measures to
ensure the safe operation of the motor.

1.2.9 Altitude and derating

In areas where the altitude is more than 1000 meters, the heat dissipation effect of the inverter is deteriorated
due to the thin air, and it is necessary to derate the use. Figure 1-2 shows the relationship between the rated
current of the inverter and the altitude.

8
 Figure 1-2 Inverter rated output current and altitude derating diagram

1.2.10 Degree of protection

The protection level IP20 of the E1 inverter refers to the degree of protection achieved when the status display
unit or keyboard is selected.

1.3 Disposal considerations

When scrapping the inverter, please note:

The electrolytic capacitor of the main circuit and the electrolytic capacitor on the printed circuit board may
explode when incinerated. Poisonous gas is generated when plastic parts are incinerated body. Please treat as
industrial waste.

Notes:
(1) Filter capacitor or common-mode inductor can be installed between VI and GND terminal or CI and GND
terminal when using analog input mode.

(2) Please use shielded cable and do well grounding, keep the wire as short as possible in order to prevent
external interference when using analog input/o output mode.

3.2.6 Communication Terminal Wiring

The inverter supplies standard RS 485 communication port

It can constitute one master one slave control system or a one master multi slaves system. The upper computer
(PC/PLC) can real time monitor the inverter in the control system and achieve complicated control function such
as remote control and spermatic, etc

(1) Remote control panel can be connected with inverter viaRS485port by plugging in the remote control panel
into RS485 port without any parameter setting. The local control panel of inverter and remote control panel can
work at the same time.

27
(2) Inverter RS 485 port and upper computer wiring as follow：

Fig. 3-11 RS485-(RS485/232)-RS232 communication wiring

(3) Multi inverters can communicate via RS485, controlled by PC/PLC as a Master shown as Fig.3-12. It also
can be controlled by one of inverters as a Master shown as Fig.3-13

Fig. 3-12 PLC communications with multi inverters

Fig. 3-13 Multi inverters communication

The more inverters connected, the more the communication interference may accure. Please make wiring as

28
above and do well grounding for inverters and motors, or adopt the following measures to prevent interference
as even above wiring can’t work.

(1) Separately power supply to PC/PLC or isolated the power of PC/PLC.

(2) Use EMI FILTER to the wire or reduce carrier frequency properly

3.3 EMC Installation Instruction

Inverter outputs PWM wave, it will produce electromagnetic noise. To reduce the interference, EMC installation
will be introduced in this section from noise suppression, wire connection, grounding, leakage current and filter
of power supply

3.3.1 Noise Suppression

Noise is unavoidable during inverter operation. Its influence over peripheral equipment is related to the noise
type, transmission means, as well as the design, install action, wiring and grounding of the driving system

29
(2) Noise Suppression Methods

Path Noise suppression methods

If a closed loop is formed between the peripheral equipment and the inverter wiring, the
Path 2 grounding leakage of the inverter will mis-operate the equipment. Solution: Remove the
grounding of the peripheral equipment.
When peripheral equipment shares the same power source with the inverter, the noise
transmitted through the power line may misoperate the peripheral equipment.
Path 3
Solution: Mount a noise filter at inverter input side or isolated the peripheral equipment with an
isolated transformer or power filter.

Equipment and signal lines that are susceptible to interference should be installed as far as
possible from the inverter. The signal line should be shielded. The shield should be grounded at
one end and should be as far away as possible from the inverter and its input and output lines. If
the signal wires must intersect the high-voltage cable, they should be orthogonal

Path 4 A high-frequency noise filter (ferrite common mode choke) is installed at the root of the input
Path 5 and output sides of the inverter to effectively suppress the radio frequency interference of the
Path 6 power line.

The motor cable should be placed in a barrier of greater thickness, such as a pipe of greater
thickness (more than 2 mm) or embedded in a cement tank. The power cable is inserted into the
metal pipe and grounded with a shielded wire (the motor cable is a 4-core cable, one of which is
grounded on the inverter side and the other side is connected to the motor casing).

Path Noise suppression methods

Avoid parallel wiring or bundling of strong and weak electric wires; try to keep away from the
Path 1 inverter installation equipment, and the wiring should be away from the input and output lines of
Path 7 the inverter. Shielded wires are used for signal and power lines. Equipment with strong electric
Path 8 field or strong magnetic field should pay attention to the relative installation position of the
inverter, and should maintain distance and orthogonality.

Table3-5 Noise suppression method

30
3.3.2 Wiring Connection and Grounding
 Please do not to wire motor cable (from inverter to motor) in parallel with power cable and keep at least
30cm from each other.
 Please try to arrange the motor cable through Control signal cable metal pipe or in metal wiring groove.
 Please use shielded cables control signal cable, and connect the shielding coat to PE terminal of inverter
with proximal grounding to inverter.
 PE grounding cable should be directly connected to the earth plate.
 The control signal cable shouldn’t be in parallel with strong electricity cable (power cable/motor cable). They
should not be bent together and should be kept away as least 20cm from each other. If cable crossing is
inevitable, please make sure it is same as Fig.3-1 4
 Please ground the control signal cable separately with power cable/motor cable.
 Please don’t connect other devices to inverter power input terminals(R/S/T).

Remark：
In the three-level menu status, if the parameter has no flashing bit, it means the function code cannot be
modified. The possible reasons are as follows:
The function code is an unmodifiable parameter, such as an actual detected status parameter, a running record
parameter, etc.
The function code cannot be modified in the running status, and can be modified after stopping.

P0.00 Control mode 0~2 1 0 ×
0: V/F control
It is suitable for applications where the load requirements are not high, or when one inverter drives multiple
motors, such as fans and pumps. It can be used in the case where one inverter drives multiple motors.

1: No speed sensor vector control

Refers to open-loop vector control, suitable for general high-performance control applications, one inverter can
only drive one motor. Such as machine tools, centrifuges, wire drawing machines, injection molding machines
and other loads.

2: Speed sensor vector control

Refers to the closed-loop vector control, the motor must be equipped with an encoder; the inverter must be
equipped with the same type of expansion card as the encoder, suitable for high-precision speed control or
torque control. Only one motor can be driven by one inverter Such as high-speed paper machinery, lifting
machinery, elevators and other loads.

selection
0：Digital setting 1(P0.02，UP/DOWN canmodify,non-retentive at power failure)
Use the keyboard's ▲, ▼, keys or knob switch to set the operating frequency. When the inverter is powered off
and powered up again, the set frequency value returns to the value of P0.02 “Digital Set Preset Frequency”.

1：Digital setting 2 (P0.02，UP/DOWN can modify, Retentive at power failure)

Operate the keyboard keys or knob switches to set the operating frequency. When the inverter is powered off
and then powered on again, the set frequency is the set frequency at the time of the last power-down, and is
corrected by the ▲, ▼ keys or the correction amounts of the terminals UP and DOWN.

2：VI analog setting（VI-GND）

The frequency setting is determined by the analog voltage of the VI terminal. The input voltage range is DC
0~10V. The correspondence between frequency and VI input is determined by function code P3.21~P3.24.

3：CI analog setting（CI-GND）

The frequency setting is determined by the CI terminal analog voltage/current. The input range is DC 0~10V (J8
jumper selects V side), DC: 4~20mA (J8 jumper selects A side). The correspondence between frequency and CI
input is determined by function code P3.21~P3.24.

70
5：Pulse setting
The frequency setting is determined by the terminal pulse frequency (the pulse signal can only be input by X5).
The correspondence between frequency and PLUSE input is determined by function code P3.31~P3.34.

6: Multi-reference
Different combinations of states of the digital input DI terminals correspond to different set frequency values. E1
can set 4 multi-segment command terminals (terminal functions 12~15), 16 states of 4 terminals, can
correspond to any 16 “multi-segment commands” through FC group function code, “multi-segment command” is
relative maximum frequency P0.05 Percentage. When the digital input DI terminal is used as the multi-segment
command terminal function, it needs to be set in the P3 group. For details, please refer to the related function
parameter description of the P3 group.

7: Simple PLC
When the frequency source is a simple PLC, the running frequency source of the inverter can be switched
between 1~16 arbitrary frequency commands. The holding time of 1~16 frequency commands and the
respective acceleration / deceleration time can also be set by the user in Pb group.

8: PID
When applying PID as the frequency source, you need to set the P6 function "PID function" related parameters.

9：485 communication
The frequency is given by the communication method. The upper computer gives the data by the communication
address 0x1000, the data format is -100.00% ~ 100.00% and 100.00% refers to the percentage of the relative
maximum frequency P0.05.

P0.10 Carrier frequency 0.5KHz～16.0KHz 0.01Hz Model setting ○

The carrier frequency primarily affects motor noise and heat loss during operation. The relationship between
carrier frequency and motor noise, leakage current, and interference is as follows:
Carrier frequency Reduce Raise
Electromagnetic noise ↑ ↓
Leakage current ↓ ↑
interference ↓ ↑
Prompt:
 In order to obtain better control characteristics, the ratio of the carrier frequency to the maximum operating
frequency of the inverter is recommended not to be lower than 36.
 When the carrier frequency is low, there is an error in the current display value.

The carrier frequency is adjusted with temperature, which means that when the driver detects that the
temperature of the radiator is high, the carrier frequency is automatically reduced to reduce the temperature rise
of the driver. When the heat sink temperature is low, the carrier frequency gradually returns to the set value.
This feature reduces the chance of a drive overheating alarm.

frequency (P0.05) to 0 frequency. (t2 in Figure 6-1).

The E1 inverter provides 4 sets of acceleration/deceleration time. The user can use the digital input terminal DI
to switch the selection. The four groups of acceleration/deceleration time are set by the following function codes:
The first group: P0.12~ P0.13;
The second group: P2.03~ P2.04;
The third group: P2.05~ P2.06;

When the inverter starts running from the stop state, if P1.02 and P1.03 are set, the DC braking starts from the

acceleration mode and acceleration time to run to the set frequency. Otherwise there is no DC braking process.

1: Rotational speed tracking restart

The actual speed of the motor being rotated is searched first, and a smooth start without impact is started from

fan that is still rotating. To ensure the accuracy of the speed search, please set the motor parameters and

Only valid for asynchronous motors, used to establish a magnetic field before the motor is running.
Pre-excitation current and pre-excitation time are described in function codes P1.03 and P1.04.

If the pre-excitation time is set to 0, the inverter cancels the pre-excitation process and starts from the start

Starting DC braking is only valid when the start mode is direct start (P1.00 is set to 0). At this time, the inverter
first performs DC braking according to the set starting DC braking current, and then starts running after the DC
braking time is started. If the DC braking time is set to 0, it will start directly without DC braking. Higher the DC
braking current means the highter the braking force. If the starting mode is asynchronous machine pre-excitation

This set of parameters is used to implement sleep and wake-up functions in water supply applications.

During the running of the inverter, when the set frequency is less than or equal to the sleep frequency of P2.49,
after the delay time of P2.50, the inverter enters the sleep state and stops automatically.

If the inverter is in the sleep state and the current running command is valid, when the set frequency is greater
than or equal to the P2.47 wake-up frequency, after the delay time of the time P2.48, the inverter starts to start.

In general, please set the wake-up frequency to be greater than or equal to the sleep frequency. When the
wake-up frequency and sleep frequency are both set to 0.00 Hz, the sleep and wake-up functions are invalid.

When the sleep function is enabled, if the frequency source uses the PID, whether the sleep state PID is
calculated or not is affected by the function code P6.28. At this time, the PID stop operation must be selected
(P6.28=1).

The functions listed in Table 6-1 are described as follows:

1~2: Positive and negative control terminals
The inverter is controlled to rotate forward and reverse by external terminals.

3: Three-wire operation control

This terminal is used to determine the inverter operation mode is the three-wire control mode. For details, please
refer to the description of function code P3.14 ("Terminal Command Method").

4~5: Positive and negative jog

FJOG is a jog forward run and RJOG is a jog reverse run. For the jog running frequency and jog
acceleration/deceleration time, see the descriptions of function codes P2.00, P2.01, and P2.02.

6~7: Frequency increment instruction UP/decrement instruction DOWN

The frequency is incremented or decremented by the control terminal instead of the operation panel for remote
control. When the frequency source is set to digital setting, the set frequency can be adjusted up and down. The
rate of change of the terminal UP/DOWN per second is set by function code P3.15.

8: Free parking input

This function has the same meaning as the free running stop defined in P1.05, but it is realized by the control
terminal for remote control.

9: Fault reset (RESET)

When the inverter has a fault alarm, the fault can be reset through this terminal. Its function is consistent with the
STOP button function of the operation panel.

93
10: Run pause
The drive decelerates to stop, but all operating parameters are memorized. Such as PLC parameters, swing
frequency parameters, PID parameters. After the terminal signal disappears, the inverter returns to the operating
state before stopping.

11: External device fault normally open / normally closed input

Through this terminal, the fault signal of the external device can be input, which is convenient for the inverter to
monitor the fault of the external device. After receiving the fault signal of the external device, the inverter
displays “E-13”, that is, the external device fault alarm. The fault signal can be either normally open or normally
closed.
As shown in Figure 6-17, X4 is the normally open input mode. Here, KM is an external device fault relay.

12～15: Multi-speed running terminal

Four multi-segment command terminals can be combined into 16 states, and each of these 16 states
corresponds to 16 command set values. The specific table below shows:

94
to the maximum frequency P0.05. In addition to the multi-segment function, the multi-segment command can
also be used as a given source of PID, or as a voltage source for VF separation control, etc., to meet the need
to switch between different given values. The multi-speed operation wiring diagram is as follows 6-16

The selection of the acceleration/deceleration time 1 to 4 can be achieved by the ON/OFF combination of the
acceleration/deceleration time terminals 1 and 2.

18: Frequency given switching

Used to switch to a given source of different frequencies.

According to the setting of the frequency source selection function code P0.19, when setting the switching
between two kinds of frequency given as the frequency timing, the terminal is used to switch between the two
frequencies given.

19: UP/DOWN setting is cleared

When the frequency is given as the digital frequency, this terminal can clear the frequency value changed by the
terminal UP/DOWN or the keyboard UP/DOWN, so that the given frequency returns to the value set by P0.02.

20: Run command switch terminal

When the running command setting mode is set to terminal control (P0.03=1), this terminal can switch between
terminal control and keyboard control.

95
When the command source is set to communication control (P0.03=2), this terminal can switch between
communication control and keyboard control.

21: Acceleration/deceleration prohibition command

Keep the motor unaffected by any external signals (except for the stop command) and maintain the current
speed.
Tip: Invalid during normal deceleration stop.
22: PID suspension
When the PID is temporarily valid, the inverter maintains the current output frequency and does not perform PID
adjustment of the frequency output.

23: PLC status reset

The PLC is paused during execution. When it is run again, the inverter can be restored to the initial state of the
simple PLC through this terminal.

24: swing frequency pause

The frequency converter outputs at the center frequency. The swing frequency function is suspended.

25: Counter input

Count the input terminal of the pulse.

26: Counter reset

The counter status is cleared.

27: length count input

The function terminal is used for fixed length control, and the length is calculated by pulse input. For details,
refer to the function introduction of PE.05~PE.06.

28: Length reset

When the function terminal is valid, the actual length function code PE.06 is set to zero.

32: Immediate DC braking

When this terminal is valid, the inverter directly switches to the DC braking state.

33: External fault normally closed input

34: Frequency setting effective terminal

If this function is set to valid, the frequency converter will not respond to the frequency change when the
frequency changes, until the terminal status is invalid.

35: PID action direction reverse terminal

When this terminal is valid, the direction of PID action is opposite to the direction set by P6.03.

36: External parking terminal 1

When the keyboard is controlled, this terminal can be used to stop the inverter, which is equivalent to the
function of the STOP button on the keyboard.

37: Control command switching terminal 2

Used for switching between terminal control and communication control. If the command source is selected as
the terminal control, the system switches to communication control when the terminal is valid; vice versa.

96
38: PID integration pause terminal
When the terminal is valid, the PID integral adjustment function is suspended, and the PID proportional
adjustment and differential adjustment functions are still valid.

39: Main frequency reference and preset frequency switching terminal

When this terminal is valid, the main source of the inverter frequency is replaced by the preset frequency
(P0.02).

40: auxiliary frequency reference and preset frequency switching terminal

When the terminal is valid, the inverter frequency reference source is replaced by the preset frequency (P2.02).

43: PID parameter switching terminal

When the PID parameter switching condition is DI terminal (P6.18=1), when the terminal is invalid, the PID
parameter uses P6.05~P6.07. When the terminal is valid, P6.15~P6.17 is used;

44~45: User-defined fault 1, 2

When the user-defined faults 1 and 2 are valid, the inverter will alarm E-32 and E-33 respectively, and the
inverter will select the action mode selected by PA.46 according to the fault protection action.

46: Reserved

47: Emergency stop

When the terminal is valid, the inverter stops at the fastest speed. During the stop process, the current remains
at the upper limit which has set. This function is used to meet the requirement that the inverter needs to stop as
soon as possible when the system is in an emergency.

48：External STOP terminal 2

In any control mode (keyboard control, terminal control and communication control), this terminal can be used to
make the inverter decelerate and stop.The deceleration time is fixed to the Dec. time 4.

49：Deceleration DC braking
When the terminal is valid, the inverter decelerates to the stop DC braking frequency and then switches over
to DC braking state.

50：Clear the current running time

When the terminal is valid, the current running time of the inverter is cleared. The function needs to be
connected with the timing operation (P2.40) and the operation time arrived (P2.41) used together.

When the voltage of the analog input is larger than the set “maximum input” (P3.18), the analog voltage is
calculated according to the “maximum input”; similarly, when the analog input voltage is less than the set
“minimum input” ( P3.16), it according to "AI low Select at the minimum input setting (P3.37 setting, calculated
with minimum input or 0.0%).

If the analog input is a current input, 1mA current is equivalent to 0.5V.

When the field analog is easily interfered, please increase the filtering time so that the detected analog tends to
be stable, but the larger the filtering time, the slower response speed of analog detection.

Please set it properly according to the actual application.

It applicable to ordinary constant torque load. When the output frequency of the inverter is 0, the output voltage

the motor.

It suitable for special loads such as dehydrators and centrifuges. By setting the P5.01~P5.06 parameters, an

2: Square V/F
It suitable for centrifugal loads such as fans and pumps.

10: V/F complete separation

Generally used in induction heating, torque motor control and other occasions. The output frequency of the
inverter is independent of the output voltage, the output frequency is determined by the frequency source and
the output voltage is determined by P5.14 (the voltage source digital setting when select separated V/F).

11: V/F half separation

V is proportional to F, but the proportional relationship can be set by separated V/F voltage source P5.13, and

P5.09 V/F slip compensation gain 0.0%～200.0% 0.1% 0.0% ○
When the motor works at V/F control mode and drives a electric load, the motor speed will decrease as load
increases. If it drives a generation load, the motor speed will increase as the load increases. By setting the slip
compensation gain value properly, the motor speed change due to load changes can be compensated to
maintain a constant motor speed.

To use the slip compensation function normally, the motor rated speed P8.05 must be correctly set according to
the motor nameplate. P8.05 is the speed at which the motor drives the rated electric load. The rated slip is the
difference between the rated speed and the speed at non-load operation. Slip compensation automatically
adjusts the output frequency of the inverter according to the rated slip and the magnitude of the motor load by
detecting the motor load in real time, thereby reducing the influence of load changes on the motor speed.

Gain adjustment method: Please adjust it around 100%. When the motor drives electric load, if the motor speed
is low, increase the gain properly; if the motor speed is high, reduce the gain properly. When the motor drives
generation load, if the motor speed is low, the gain is properly reduced. If the motor speed is high, increase the
gain properly.

where easy to give overvoltage alarm during inverter deceleration process, it is necessary to increase the
overexcitation gain. However, if the over-excitation gain is too large, it will easily lead to an increase in the output
current, which needs to be weighed in different application. It is recommended to set the over-excitation gain to

P7.11 is used to set the number of decimal places for load speed display. The following gives an example to
explain how to calculate the load speed:

Assume that P7.05 (Load speed display coefficient) is 2.000 and P7.11 is 2 (2 decimal places). When the
running frequency of the AC drive is 40.00 Hz, the load speed is 40.00 * 2.000 = 80.00 (display of 2 decimal
places).

If the AC drive is in the stop state, the load speed is the speed corresponding to the set frequency, namely, "set
load speed". If the set frequency is 50.00 Hz, the load speed in the stop state is 50.00*2.000 = 100.00 (display of

It is applicable to scenarios where complete auto-tuning cannot be performed because the asynchronous motor
cannot be disconnected from the load. Before performing static auto-tuning, properly set the motor type and
motor nameplate parameters of P8.00 to P8.05 first. The AC drive will obtain parameters of P8.06 to P8.08 by

2: Asynchronous motor with-load auto-tuning

To ensure the dynamic control performance of the inverter, please select motor complete auto-tuning and make
sure the motor is disconnected from the load and in non-load state. During the process of complete auto-tuning,
the AC drive performs static auto-tuning first and then accelerates to 80% of the rated motor frequency within
the acceleration time set in P0.12. The AC drive keeps running for a certain period and then decelerates to stop
within deceleration time set in P0.13.

Before performing complete auto-tuning, properly set the motor type, motor nameplate parameters of P8.00 to

The speed dynamic response characteristics in vector control can be adjusted by setting the proportional gain
and integral time of the speed regulator.

To achieve a faster system response, please increase the proportional gain and reduce the integral time.But too
large value may lead to system oscillation.

The recommended adjustment method is as follows: If the factory setting cannot meet the requirements, please
make proper adjustment base on the factory default. Increase the proportional gain first to ensure that the
system does not oscillate, and then reduce the integral time to ensure that the system has quick response and
small overshoot.

NOTE: Improper PI parameter setting may cause too large speed overshoot or overvoltage fault may even occur
when the overshoot drops.

During the deceleration operation of the inverter, due to the influence of load inertia, the actual rate of decline of
the motor speed may be lower than the rate of decrease of the output frequency. At this time, the motor will feed
back power to the inverter which will cause the DC bus voltage of the inverter to rise. If no measures are taken,
an overvoltage trip will occur.

If the overvoltage stall gain is set to 0, the overvoltage stall function is disabled.

The overvoltage stall protection function detects the bus voltage during the deceleration operation of the inverter
and compares it with the stall overvoltage point set by the stall prevention voltage. If the stall prevention voltage
is exceeded, the inverter output frequency stops decreasing, when the bus voltage is detected again lower than

In the case of instantaneous power failure or sudden voltage drop, the inverter compensates the DC bus voltage
of the inverter by reducing the output speed and reducing the output voltage of the inverter to maintain the
inverter running.

If PA.55=1, the inverter will decelerate when the power is suddenly lost or the voltage suddenly drops. When the
bus voltage returns to normal, the inverter will accelerate to the set frequency. The basis for determining that the
bus voltage is back to normal is that the bus voltage is normal and the duration is longer than PA.57 sets the
time.

If PA.55=2, the inverter will decelerate until it stops when there is an instantaneous power failure or a sudden
drop in voltage.

In three applications, the dimension of the multi-segment instruction is relative value, the range is
-100.0%~100.0%, which is the percentage of the relative maximum frequency when used as the frequency
source; when it is the VF separation voltage source, it is relative to the rated voltage of the motor. Percentage;

since the PID given is originally a relative value, the multi-segment instruction does not require a dimension
conversion as a PID setting source.

The multi-segment instruction needs to be switched according to the different states of the multi-function digital

The simple PLC function has two functions: as a frequency source or as a voltage source for VF separation.

Figure 6-35 is a schematic diagram of a simple PLC as a frequency source. When the simple PLC is used as the
frequency source, the positive and negative of Pb.00~Pb.15 determines the running direction. If it is negative,
the inverter runs in the opposite direction.

As a frequency source, the PLC has three modes of operation, and does not have these three modes as a VF

The swing frequency function refers to the inverter output frequency, which swings up and down with the set

This parameter is used to determine the value of the swing value and the kick frequency.

When setting the swing relative to the center frequency (PE.00 = 0), the swing AW = primary and secondary
frequency given × swing amplitude PE.01. When setting the swing relative to the maximum frequency (PE.00 =

The amplitude of the kick frequency is the percentage of the frequency of the kick frequency relative to the swing
when the swing frequency is running, that is, the burst frequency = swing AW × kick frequency amplitude PE.02.
If the swing is selected relative to the center frequency (PE.00 = 0), the burst frequency is the change value. If
the swing is selected relative to the maximum frequency (PE.00 = 1), the burst frequency is a fixed value.

The jump function is to fix the analog amount corresponding set value to the value of the jump point when the

For example, the voltage of the analog input AI fluctuates around 5.00V, the fluctuation range is 4.90V~5.10V,
the minimum input 0.00V of AI corresponds to 0.0%, and the maximum input 10.00V corresponds to 100.%, then
the detected AI corresponds to the setting. It fluctuates between 49.0% and 51.0%.

Set the AI setting jump point PF.36 to 50.0%, and set the AI setting jump width PF.37 to 1.0%. When the AI
input is performed, after the jump function processing, the corresponding AI input corresponding setting is fixed

Flow compensation coefficient
In the high frequency region, the motor drive current is small, and the speed of the motor drops greatly with
respect to the same stall current below the rated frequency. In order to improve the operating characteristics of
the motor, the stall operating current above the rated frequency can be reduced, in some centrifuges. When the
operating frequency is high, requiring several times of weak magnetic field and large load inertia, this method
has a good effect on the acceleration performance.

Excessive speed action current exceeding the rated frequency = (fs/fn) * k * LimitCur;

Fs is the running frequency, fn is the rated frequency of the motor, k is F3-21 "double speed over loss speed
action current compensation coefficient", LimitCur is E9.00 "overcurrent speed action current";

Figure 6-38 Schematic diagram of double speed over loss speed

146
Remarks:
Over-current running current 150% means 1.5 times the rated current of the inverter;
For high-power motors, the carrier frequency is below 2 kHz. Due to the increase of the ripple current, the
wave-by-wave current-limit response starts before the over-speed prevention action, and the torque is
insufficient. In this case, reduce the over-speed prevention operation current.

● Inverter bus voltage limit (and brake resistor turn-on voltage setting)
If the bus voltage exceeds the overvoltage stall point of 760V, it means that the electromechanical system is
already in the power generation state (motor speed > output frequency), the overvoltage stall will work, adjust
the output frequency (consuming the excess power), the actual deceleration time will be automatically pulled.
Long, avoid trip protection, if the actual deceleration time can not meet the requirements, you can increase the
overexcitation gain appropriately.

7.1 Failure phenomena and countermeasures
When an abnormality occurs in the inverter, the LED digital tube will display the function code and its contents
corresponding to the fault. The fault relay will operate and the inverter will stop output. If the motor is rotating, it
will stop freely until it stops rotating. The types of faults that may occur on the E1 are shown in Table 7-1. When
the inverter is faulty, the user should first check according to the prompts of the table, and record the fault
phenomenon in detail. When technical service is required, please contact our after-sales service and technical
support department or our agents.

 Chapter 9 Serial Port RS485 Communication Protocol

9.1 Communication Overview

The company's series of inverters provide users with a common RS485 communication interface for industrial
control. The communication protocol adopts the MODBUS standard communication protocol. The inverter can
be used as a slave to communicate with the host computer (such as PLC controller and PC) with the same
communication interface and using the same communication protocol to realize centralized monitoring of the
inverter. Can use a frequency converter as the host computer connects several inverters of the company as
slaves through the RS485 interface. To achieve multi-machine linkage of the inverter. The remote control
keyboard can also be connected through the communication port. Realize the user's remote operation of the
inverter.
The MODBUS communication protocol of this inverter supports the RTU mode. The following is a detailed
description of the inverter communication protocol.

9.2 Communication Protocol Description

9.2.1 Communication Network Mode
(1) The inverter acts as a slave network:

Figure 9-1 Schematic diagram of the unit network

(2) Multi-machine linkage networking mode:

Figure 9-2 Schematic diagram of multi-machine linkage networking

156
9.2.2 Communication protocol mode
The inverter can be used as a host or as a slave in the RS485 network. When used as a master, it can control
other inverters of the company to achieve multi-level linkage. When used as a slave, the PC or PLC can be used
as a host. Control the inverter to work. The specific communication methods are as follows:

 The inverter is a slave, master-slave point-to-point communication. When the host sends a command
using the broadcast address, the slave does not answer.
 As the host, the inverter uses the broadcast address to send commands to the slave, and the slave
does not answer.
 The user can set the local address, baud rate and data format of the inverter by keyboard or serial
communication.
 The slave reports the current fault information in the response frame of the last polling of the host.

9.2.3 Communication interface mode

Communication is RS485 interface, asynchronous serial, half duplex transmission. The default communication
protocol mode uses RTU mode.
The default data format is: 1 start bit, 8 data bits, 2 stop bits, no check.
The default rate is 9600bps. For the communication parameter settings, see PC.00~PC.05 function code.

The main function of Modbus is to read and write parameters, and different function codes determine different
operation requests. The inverter Modbus protocol supports the following function code operations:

The function code parameters, control parameters and status parameters of the inverter are mapped to Modbus
read/write registers. The read and write characteristics and range of the function code parameters follow the
instructions in the inverter user manual. The control parameters and status parameters of the inverter are
separately assigned addresses. The correspondence between the function code group number and its mapped
register address high byte is as follows:
1. Address 0xF0-0xFF, corresponding to function code parameter group P0-PF;
For example, to query the parameter P0.03 of the P0 group, the corresponding address is 0xF003;
For example, to query the parameter P6.10 of the P6 group, the corresponding address is 0xF60A;
For example, to query the PB.16 parameter of the PB group, the corresponding address is 0xFB10.
2. The address 0x500x is the reading address of the inverter status parameters;
(Note: 0x5000 can be read and written, the subsequent addresses can only be read, not write)
3. The address 0x600x is the address of the inverter control parameter group;
4. The address 0x8000 is the address of the inverter fault status;
5. The address 0x8001 is the abnormal communication address of the inverter (valid when PC.05 = 0);

CRC check
Considering the need to increase the speed, CRC-16 is usually implemented in a tabular manner. The following
is the C source code for implementing CRC-16. Note that the final result has been exchanged for the high and
low bytes, that is, the result is the CRC checksum to be sent. .

uint16 CrcValueByteCaA0(const uint16 *data, uint16 len)

{
uint16 CRCValue = 0xFFFF;
uint16 tmp;
uint16 a;
while (len--)
{
tmp = *(data++);
a = (CRCValue ^ tmp) & 0x000F;
CRCValue >>= 4;
CRCValue ^= crc16Table[a];
a = (CRCValue & 0x000F) ^ (tmp >> 4);
CRCValue >>= 4;
CRCValue ^= crc16Table[a];
} return crcValue;

Response delay: refers to the interval between the end of the inverter data reception and the transmission of
data to the host computer. If the response delay is less than the system processing time, the response delay is
based on the system processing time. If the response delay is longer than the system processing time, the
system waits until the response delay time arrives before the system processes the data. send data.

PC.04 Serial communication timeout 0.0s～60.0s 0.1s 0.0s ○
When the function code is set to 0.0 s, the communication timeout time parameter is invalid.
When the function code is set to a valid value, if the interval between one communication and the next
communication exceeds the communication timeout period, the system will report a communication failure error
(E-15). Normally, it is set to be invalid. If you set the secondary parameters in a continuous communication
system, you can monitor the communication status.
