Sensorless flux vector control (SVC) 0
P0.01 Speed control mode 2 ★
V/F control 2
0: Sensorless flux vector control for asynchronous motors (SVC)
This is for high-performance control applications such as machine tool, centrifuge, wire
drawing machine and injection molding machine. One inverter can only drive one motor.

2: Voltage/Frequency control (V/F)

It is applicable to applications with low load requirements or applications where one
inverter operates multiple motors, such as fans and pumps.
Notes:
If vector control is used, motor auto-tuning must be performed because the advantages of vector
control can only be utilized after correct motor parameters are obtained. Better performance can
be achieved by adjusting speed regulator parameters in group P2.

For the permanent magnetic synchronous motor (PMSM), the D-100 does not support SVC. FVC is
used generally. In some low-power motor applications, you can also use V/F.

0: Keyboard setting (P0.08, UP/DOWN editable, not retentive at power off)

The initial value of the set frequency is the value of P0.08 (Preset frequency). You can change the
frequency by pressing the keyboard (or using the UP/DOWN function of input terminals). When
the inverter is powered on again after power off, the frequency reverts to the value of P0.08.

1: Keyboard setting (P0.08, UP/DOWN editable, retentive at power off)

The initial value of the set frequency is the value of P0.08 (Preset frequency). You can change the
set frequency by pressing the keyboard (or using the UP/DOWN function of input terminals).
When the inverter is powered on again after power off, the frequency is the value memorized at the
moment of the last power off.
Note that P0.23 determines whether the set frequency is memorized or cleared when the
inverter stops. It is related to stop rather than power off.

Jumper J6 determines whether to use AI3 terminal or keyboard potentiometer as command
source. If AI3 terminal is selected, Jumper J5 determines whether to use 0-10V voltage input or 0-
20 mA current input

6: Multi-speed operation setting

In multi-speed operation setting mode, combinations of different DI terminal states correspond
to different set frequencies. The D-100 supports maximum 16 speeds implemented by 16 state
combinations of four DI terminals in Group PC. The multi-speed operation setting indicates
percentages of the value of P0.10 (Maximum output frequency).
If a DI terminal is used for the multi-speed operation setting, you need to set in group P4.

7: Simple PLC setting

When the simple programmable logic controller (PLC) mode is used as the frequency source, the
running frequency of the inverter can be switched over among the 16 frequency references. You
can set the holding time and acceleration/deceleration time of the 16 frequency references. For
details, refer to the descriptions of Group PC.

8: PID control setting

The output of PID control is used as the running frequency. PID control is generally used in on-
site closed-loop control, such as constant pressure closed-loop control and constant tension closed-
loop control. When applying PID as the frequency source, you need to set in group PA.

selection Reverse direction 1
You can change the rotation direction of the motor just by modifying this parameter without
changing the motor wiring. Modifying this parameter is equivalent to exchanging any two of
the motor's U, V, W wires.

The motor will resume running in the original direction after parameter initialization. Do not use
this function in applications where changing the rotating direction of the motor is prohibited
after system commissioning is complete.
P0.10 Maximum frequency 50.00Hz~320.00Hz 50.00Hz ★
When the frequency source is AI, pulse setting (DI5), or multi-speed, value of this
parameter determines the 100% frequency.

The output frequency of the D-100 can reach 3200 Hz. To take both frequency reference
resolution and frequency input range into consideration, you can set the number of decimal places
for frequency reference in P0.22.

communication, the setting is similar to that of the main frequency source X. For details, see
the description of P0.03.

For example, to avoid runaway in torque control mode in winding application, you can set the

Please refer to table below:
Carrier frequency Low → High

The factory setting of carrier frequency varies with the inverter power. If you need to modify the
carrier frequency, note that if the set carrier frequency is higher than factory setting, it will lead to
an increase in temperature of the inverter's heatsink. In this case, you need to de-rate the inverter.
Otherwise, the inverter may overheat and alarm.

It is used to set whether the carrier frequency is adjusted based on the temperature. The Inverter
automatically reduces the carrier frequency when detecting that the heatsink temperature is high.
The inverter sets the carrier frequency to the set value when the heatsink temperature becomes
normal. This function reduces the overheat alarms.

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 P1.00 to P1.05 first. The inverter will obtain parameters of P1.06 to P1.08 by static auto-tuning.
Set this parameter to 1, and press RUN. Then, the inverter starts static auto-tuning 1.

2: Asynchronous motor complete auto-tuning
To perform this type of auto-tuning, ensure that the motor is disconnected from the load. During the
process of complete auto-tuning, the inverter performs static auto-tuning first and then accelerates
to 80% of the motor rated frequency within the acceleration time set in P0.17. The inverter keeps
running for a certain period and then decelerates to stop within deceleration time set in P0.18.

Before performing complete auto-tuning, properly set the motor type, motor nameplate parameters
of P1.00 to P1.05, "Encoder type” (P1.28) and "Encoder pulses per revolution” (P1.27) first.
The inverter will obtain motor parameters of P1.06 to P1.10, "A/B phase sequence of ABZ

Speed loop PI parameters can vary with running frequencies of the inverter.

• If the running frequency is less than or equal to "Switchover frequency 1" (P2.02), the speed
loop PI parameters are P2.00 and P2.01.

• If the running frequency is equal to or greater than "Switchover frequency 2" (P2.05), the
speed loop PI parameters are P2.03 and P2.04.

• If the running frequency is between P2.02 and P2.05, the speed loop PI parameters are obtained from
the linear switchover between the two groups of PI parameters, as shown in figure below.

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, increase the proportional gain and reduce the integral time.
Be aware that this may lead to system oscillation.
The recommended adjustment method is as follows:

If the factory setting cannot meet the requirements, fine tune the PI parameters. 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.

Improper PI parameter setting may cause serious speed overshoot, and overvoltage fault may
even occur when the overshoot drops.

decrease the proportional gain or integral gain here.

2: Square V/F
It is applicable to centrifugal loads such as fan and pump.

3 to 8: V/F curve between linear V/F and square V/F

10: V/F complete separation

In this mode, the output frequency and output voltage of the Inverter are independent. The output
frequency is determined by the frequency source, and the output voltage is determined by
"Voltage source for V/F separation" (P3.13).
It is applicable to induction heating, inverse power supply and torque motor control.

11: V/F half separation

In this mode, V and F are proportional and the proportional relationship can be set in P3.13. The
relationship between V and F are also related to the motor rated voltage and motor rated
frequency in Group P1.
Assume that the voltage source input is X (0 to 100%), the relationship between V and F is:
V/F = 2 * X * (motor rated voltage) / (motor rated frequency)

To compensate the low frequency torque characteristics of V/F control, user can boost the
output voltage of the inverter at low frequency by modifying P3.01.

If the torque boost is set to too large, the motor may overheat, and the inverter may
suffer overcurrent.

If the load is large and the motor startup torque is insufficient, increase the value of P3.01. If the
load is small, decrease the value of P3.01. If it is set to 0.0, the inverter performs automatic torque
boost. In this case, the inverter automatically calculates the torque boost value based on motor
parameters including the stator resistance.

P3.02 specifies the frequency under which torque boost is valid. Torque boost becomes
invalid when this frequency is exceeded.

These six parameters are used to define the multi-point V/F curve.
The multi-point V/F curve is set based on the motor's load characteristic. The
relationship between voltages and frequencies is:
V1 < V2 < V3, F1 < F2 < F3
At low frequency, higher voltage may cause overheat or even motor burn-out as well as
overcurrent stall or overcurrent protection of the inverter.

%
This parameter is valid only for the asynchronous motor.

It can compensate the rotational speed slip of the asynchronous motor when the load of the
motor increases, stabilizing the motor speed in case of load change.

If this parameter is set to 100%, it indicates that the compensation when the motor bears rated load
is the motor rated slip. The motor rated slip is automatically obtained by the inverter through
calculation based on the motor rated frequency and motor rated rotational speed in group P1.

Generally, if the motor rotational speed is different from the target speed, slightly adjust P3.09.
P3.10 V/F over-excitation gain 0~200 64 ☆

During deceleration of the inverter, over-excitation can restrain rise of the DC bus voltage, preventing the
overvoltage fault. The larger the over-excitation is, the better the restraining result is.

Increase the over-excitation gain if the inverter is liable to overvoltage error during deceleration.
However, too large over-excitation gain may lead to an increase in the output current. Set P3.09 to
a proper value in actual applications.

Set the over-excitation gain to 0 in the applications where the inertia is small and the DC
bus voltage will not rise during motor deceleration or where there is a braking resistor.

P3.11 V/F oscillation suppression gain 0~100 - ☆

Set this parameter to a value as small as possible in the prerequisite of efficient

oscillation suppression to avoid influence on V/F control.

Set this parameter to 0 if the motor has no oscillation. Increase the value properly only when the
motor has obvious oscillation. The larger the value is, the better the oscillation suppression
result will be.

When the oscillation suppression function is enabled, the motor rated current and no-load current must
be correct. Otherwise, the V/F oscillation suppression effect will not be satisfactory.

improve acceleration performance.

0: Direct start
-If the startup DC braking time is set to 0, the inverter starts to run from the startup frequency.
-If the startup DC braking time is not 0, the inverter performs DC braking first and then starts to run
from the startup frequency. It is applicable to small-inertia load application where the motor is
likely to free rotate at startup.

1: Speed tracking
The inverter judges the rotational speed and direction of the motor first and then starts from the
tracked frequency. Such smooth start has no impact on the rotating motor. It is applicable to the
restart upon instantaneous power failure of large-inertia load. To ensure the performance of
rotational speed tracking restart, set the motor parameters in group P1 correctly.

2: Pre-excited start
It is valid only for asynchronous motor and used for building the magnetic field before the
motor runs. For pre-excited current and pre-excited time, see parameters of P6.05 and P6.06.
-If the pre-excited time is 0, the inverter cancels pre-excitation and starts from startup frequency.
-If the pre-excited time is not 0, the inverter pre-excites first before startup, improving the dynamic
response of the motor.

time
To ensure the motor torque at inverter startup, set a proper startup frequency. In addition, to
build excitation when the motor starts up, the startup frequency must be held for a certain period.

The startup frequency (P6.03) is not restricted by the frequency lower limit. If the target (digital
setting) frequency is lower than the startup frequency, the inverter will not start and stays in the
standby state.

-52-
During switchover between forward rotation and reverse rotation, the startup frequency holding time
is disabled. The holding time is not included in the acceleration time but in the running time of
simple PLC.

Example 1:
P0.03 = 0 The frequency source is digital setting.
P0.08 = 2.00Hz The digital setting frequency is 2.00 Hz.
P6.03 = 5.00Hz The startup frequency is 5.00 Hz.
P6.04 = 2.0s The startup frequency holding time is 2.0s.

In this example, the Inverter stays in the standby state and the output frequency is 0.00 Hz.

Example 2:
P0.03 = 0 The frequency source is digital setting.
P0.08 = 10.00Hz The digital setting frequency is 10.00 Hz.
P6.03 = 5.00Hz The startup frequency is 5.00 Hz.
P6.04 = 2.0s The startup frequency holding time is 2.0s.

In this example, the inverter accelerates to 5.00 Hz, and then accelerates to the set frequency 10.00Hz
after 2s.

time/Pre-excited time
Startup DC braking is generally used during restart of the inverter after motor stops. Pre-excitation is
used to make the inverter build magnetic field before startup to improve the responsiveness.

Startup DC braking is valid only for direct start (P6.00 = 0). In this case, the inverter performs DC
braking at the set startup DC braking current. After the startup DC braking time, the inverter starts to
run. If the startup DC braking time is 0, the inverter starts directly without DC braking. The larger
the startup DC braking current is, the larger the braking force is.

If the startup mode is pre-excited start (P6.00 = 3), the inverter builds magnetic field based on the
pre-excited current. After the pre-excited time, the inverter starts to run. If the pre-excited time is
0, the inverter starts directly without pre-excitation.

The startup DC braking current or pre-excited current is a percentage relative to the base value.

• If the motor rated current is less than or equal to 80% of the inverter rated current, the base value is
the motor rated current.

• If the motor rated current is greater than 80% of the inverter rated current, the base value is 80% of
the inverter rated current.

During the process of decelerating to stop, the inverter starts DC braking when the running frequency
is lower than the value set in P6.11.
 P6.12 (Stop DC braking waiting time)

When the running frequency decreases to the initial frequency of stop DC braking, the inverter stops
output for a certain period and then starts DC braking. This prevents faults such as overcurrent
caused due to DC braking at high speed.
 P6.13 (Stop DC braking current)
This specifies the output current at DC braking and is a percentage relative to the base value.
o If the motor rated current is less than or equal to 80% of the inverter rated current, the base
value is the motor rated current.
o If the motor rated current is greater than 80% of the inverter rated current, the base value is
80% of the inverter rated current.
 P6.14 (Stop DC braking time)
This specifies the holding time of DC braking. If it is set to 0, DC braking is cancelled.

P6.15 Brake use ratio 0%~100% 100% ☆

It is valid only for the inverter with internal braking unit and is used to adjust the duty ratio of the
braking unit. The larger this value, the better the braking result. However, too large value causes
great fluctuation of the inverter bus voltage during the braking process.

an example to explain how to calculate the load speed:

If P7.06 (Load speed display coefficient) is 2.000 and P7.12 one’s place is 2. When the running
frequency of the inverter is 40.00 Hz, the load speed is 40.00 x 2.000 = 80.00 (display of 2 decimal

If the inverter 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 50.00Hz, the load speed in the stop state is 50.00 x
2.000 = 100.00 (display of 2 decimal places).

These parameters are used to define the set frequency and acceleration/deceleration time of the
inverter when Jogging. The startup mode is "Direct start" (P6.00 = 0) and the stop mode is
"Decelerate to stop" (P6.10 = 0) during jogging.

The D-100 provides a total of four groups of acceleration/deceleration time. P0.17 and P0.18 are the
first group. Definitions of four groups are the same. You can switch over between the four groups
through different combinations of DI terminals. For more details, see P4.01 to P4.05.

P8.10 Jump frequency 2 0.00Hz~ maximum frequency 0.00Hz ☆

P8.11 Frequency jump amplitude 0.00Hz~ maximum frequency 0.00Hz ☆

If the set frequency is within the frequency jump range, the actual running frequency is the jump frequency
nearby. Setting jump frequency helps to avoid the mechanical resonance point of the load. D-100 supports
two jump frequencies. If both are set to 0, the frequency jump function is disabled. The principle of the
jump frequencies and jump amplitude is shown in the following figure.

P8.12 FWD/REV dead-zone time 0.00s~3000.0s 0.0s ☆

Run at zero speed 2
This is to set the inverter running mode when the set frequency is lower than frequency lower limit.
P8.15 Droop control rate 0.00Hz~10.00Hz 0.00Hz ☆
Droop control allows for slight speed differences between master and slaves so as to avoid
conflicts. The default value is 0.00Hz. Droop control is only needed when both master and slave are
using speed control. Please fine tune to find the most appropriate droop control value.
Please do not set P8.15 too large; otherwise when load is large, steady state speed will drop. Both
master and slave need to set droop control rates.
Droop speed = synchronous frequency * torque output * (P8.15/10)
For example, P8.15=1.00, synchronous frequency is 50Hz, torque output is 50%; then
inverter actual frequency is 50 – 50*(50%)*(1.00/10) =47.5Hz

threshold
If the accumulative power-on time (P7.13) reaches the value set in this parameter, the corresponding
DO terminal becomes ON.
For example, combining DI/DO functions, to implement the function that the inverter reports an
alarm when the actual accumulative power-on time reaches the threshold of 100 hours, perform the
setting as follows:
1) Set DI1 to user-defined fault 1: P4.00 = 44.
3) Set DO1 to power-on time reached: P5.04 = 24.
4) Set the accumulative power-on time threshold to 100h: P8.16 = 100h.
Then, the inverter outputs 26=E.ArA when the accumulative power-on time reaches 100 hours.
Accumulative running time

It is used to set the accumulative running time threshold of the Inverter. If the accumulative running time

This parameter is used to set whether to enable the safety protection. If it is set to 1, the inverter
does not respond to the still valid run command upon inverter power-on (for example, an input
terminal is ON before power-on). The inverter responds only after the run command is
cancelled and becomes valid again.

In addition, the inverter does not respond to the still valid run command upon fault reset. The run
protection can be disabled only after the run command is cancelled.

In this way, the motor can be protected from responding to run commands upon power-on or
fault reset in unexpected conditions.

If the running frequency is higher than the value of P8.19, the corresponding DO terminal

These two parameters are respectively used to set the detection value of output frequency and
hysteresis value upon cancellation of the output. The value of P8.20 is a percentage of the hysteresis
frequency to the frequency detection value (P8.19).

The FDT function is shown in the following figure.

P8.21 Frequency reached detection range 0~100% (maximum frequency) 0.0% ☆

If the Inverter running frequency is within this range of the set frequency, the corresponding DO
terminal becomes ON.

This parameter is used to set the range within which the output frequency is detected to reach the
set frequency. The value of this parameter is a percentage relative to the maximum frequency. The
detection range of frequency reached is shown in the following figure.

When the inverter is in running state, if the set frequency is lower than or equal to the dormant
frequency (P8.51), the inverter enters the dormant state and stops automatically after the
dormant delay time (P8.52).
When the inverter is in dormant state and the current running command is effective, if the set
frequency is higher than or equal to the wakeup frequency (P8.49), the inverters starts up after the
wakeup delay time (P8.50).
Generally, set the wakeup frequency equal to or higher than the dormant frequency. If the wakeup
frequency and dormant frequency are set to 0, the dormant and wakeup functions are disabled.

When the dormant function is enabled, if the frequency source is PID, whether PID operation is
performed in the dormant state is determined by PA.28. In this case, select PID operation enabled

The motor overload protective function is disabled. The motor is exposed to potential overheating.
A thermal relay is suggested to be installed between the Inverter and the motor.

P9.00 = 1
The inverter judges whether the motor is overloaded according to the inverse time-lag curve of the
motor overload protection.
The inverse time-lag curve of the motor overload protection is:
Motor Current (percentage of motor rated current) Overload time (minutes)

195% 1 (60s)
225% 0.5 (30s)
245% 0.17 (10s)

P9.01 can increase or decrease the overload time by linear proportions. If the value of P9.01 is set
too large, damage to the motor may result because the motor overheats but the Inverter does not
report the alarm.

 Example 1: Motor rated current is 100A.

If P9.01=1 (default), when motor current reaches 125% of 100A (125A) and lasts for 40
minutes, the inverter will output 11=E.oLt;
If P9.01=1.2, when motor current reaches 125% of 100A (125A) and lasts for 40*1.2=48
minutes, the inverter will output 11=E.oLt.

 Example 2: Inverters needs to output 11=E.oLt after motor running 2 minutes at 150%
current. 150% (I) current is between 145% (I1) and 155% (I2); overload time should be between 6
minutes (T1) and 4 minutes (T2).

If P9.01=1 (default), T=T1+(T2-T1) * (I-I1)/(I2-I1) =4+(6-4) *(150%-145%)/ (155%-145%)=5

The inverter can give a pre-warning signal to the control system via DO or relay before motor

For example, P9.01=1, P9.02=80%, when motor current reaches 145% and lasts for 4.8 minutes
(80%*6), inverter will output motor overload pre-warning (P5.01=6).

4.12 PID functions: PA.00-PA.28
PID control is a general process control method. By performing proportional, integral and differential
operations on the difference between the feedback signal and the target signal, it adjusts the output
frequency and constitutes a feedback system to stabilize the controlled counter around the target
value. It is applied to process control such as flow control, pressure control and temperature control.

For example, the unwinding tension control requires reverse PID action.

This parameter is a non-dimensional unit. It is used for PID setting display (d0.15) and PID

It decides the regulating intensity of the PID regulator. The higher the Kp1 is, the larger the
regulating intensity is. The value 100.0 indicates when the deviation between PID feedback and
PID setting is 100.0%, the adjustment amplitude of the PID regulator on the output frequency
reference is the maximum frequency.
 Integral time Ti1:
It decides the integral regulating intensity. The shorter the integral time is, the larger the regulating
intensity is. When the deviation between PID feedback and PID setting is 100.0%, the integral
regulator performs continuous adjustment for the time set in PA. 06. Then the adjustment
amplitude reaches the maximum frequency.
 Differential time Td1:
It decides the regulating intensity of the PID regulator on the deviation change. The longer the
differential time is, the larger the regulating intensity is. Differential time is the time within
which the feedback value change reaches 100.0%, and then the adjustment amplitude reaches the
maximum frequency.

In some applications, PID parameters switchover is required when one group of PID
parameters cannot satisfy the requirement of the whole running process.

These parameters are used for switchover between two groups of PID parameters. Regulator
parameters PA.15 to PA.17 are set in the same way as PA.05 to PA.07.

The switchover can be implemented either via a DI terminal or automatically implemented based on
the deviation.
If you select switchover via a DI terminal, the DI must be allocated with function 43 "PID
parameter switchover". If the DI is OFF, group 1 (PA.05 to PA.07) is selected. If the DI is
ON, group 2 (PA.15 to PA.17) is selected.

If you select automatic switchover, when the absolute value of the deviation between PID feedback
and PID setting is smaller than the value of PA.19, group 1 is selected. When the absolute value of
the deviation between PID feedback and PID setting is higher than the value of PA.20, group 2 is
selected. When the deviation is between PA.19 and PA.20, the PID parameters are the linear
interpolated value of the two groups of parameter values.

When the Inverter starts up, the PID starts closed-loop algorithm only after the PID output is fixed

with the set frequency as the center. The trace of running frequency at the time axis is shown in the

The preceding parameters are used for fixed length control.

The length information is collected by DI terminals. PB.06 (Actual length) is calculated by dividing the
number of pulses collected by the DI terminal by PB.07 (Number of pulses each meter).

When the actual length PB.06 exceeds the set length in PB.05, the DO terminal allocated
with function 10 (Length reached) becomes ON.

During the fixed length control, the length reset operation can be performed via the DI
terminal allocated with function 28. For details, see the descriptions of P4.00 to P4.09.

Allocate corresponding DI terminal with function 27 (Length count input) in applications. If

the pulse frequency is high, DI5 must be used.

The count value needs to be collected by DI terminal. Allocate the corresponding DI terminal

When the count value reaches the set count value (PB.08), the DO terminal allocated with
function 8 (Set count value reached) becomes ON. Then the counter stops counting.

When the counting value reaches the designated counting value (PB.09), the DO terminal allocated
with function 9 (Designated count value reached) becomes ON. Then the counter continues to
count until the set count value is reached.

PB.09 should be equal to or smaller than PB.08.

D-100 provides DI terminals with two torque related functions, function 29 (Torque control
prohibited) and function 46 (Speed control/Torque control switchover). The two DI terminals need to
be used together with B0.00 to implement speed control/torque control switchover.

If the DI terminal allocated with function 46 (Speed control/Torque control switchover) is OFF, the
control mode is determined by B0.00. If the DI terminal allocated with function 46 is ON, the
control mode is reverse to the value of B0.00.

However, if the DI terminal with function 29 (Torque control prohibited) is ON, the Inverter is
fixed to run in the speed control mode.

B0.01 is used to set the torque setting source. There are a total of eight torque setting sources.

The torque setting is a relative value. 100.0% corresponds to the Inverter's rated torque. The
setting range is -200.0% to 200.0%, indicating the inverter's maximum torque is twice of the
inverter's rated torque.

If the torque setting is positive, the inverter rotates in forward direction. If the torque setting is
negative, the inverter rotates in reverse direction.

DPWM switchover
B5.00 0.00Hz~15.00Hz 12.00Hz ☆
frequency upper limit
This parameter is valid only for V/F control.

It is used to determine the wave modulation mode in V/F control of asynchronous motor. If the
frequency is lower than the value of this parameter, the waveform is 7 -segment continuous
modulation. If the frequency is higher than the value of this parameter, the waveform is 5 -segment
intermittent modulation.

The 7-segment continuous modulation causes more loss to switches of the Inverter but smaller
current ripple. The 5-segment intermittent modulation causes less loss to switches of the Inverter
but larger current ripple. This may lead to motor running instability at high frequency. Do not
modify this parameter generally.

For instability of V/F control, refer to parameter P2.11. For loss to Inverter and temp erature rise,
refer to parameter P0.15.
Asynchronous modulation 0
B5.01 PWM modulation mode 0 ☆
Synchronous modulation 1
This parameter is valid only for V/F control.

Synchronous modulation indicates that the carrier frequency varies linearly with the change of the
output frequency, ensuring that the ratio of carrier frequency to output frequency remains
unchanged. Synchronous modulation is generally used at high output frequency, which helps
improve the output voltage quality.

At low output frequency (100 Hz or lower), synchronous modulation is not required. This is
because asynchronous modulation is preferred when the ratio of carrier frequency to output
frequency is high.

Synchronous modulation takes effect only when the running frequency is higher than 85 Hz. If the
frequency is lower than 85 Hz, asynchronous modulation is always used.
Dead zone compensation No compensation 0

Generally, you need not modify this parameter. Try to use a different compensation mode only
when there is special requirement on the output voltage waveform quality or oscillation occurs on
the motor.
Random PWM invalid 0
B5.03 Random PWM depth 0 ☆
Random PWM depth selection 1~10

The setting of random PWM depth can make the shrill motor noise softer and reduce the
electromagnetic interference. If this parameter is set to 0, random PWM is invalid.
Disabled 0
B5.04 Rapid current limit 1 ☆
Enabled 1
The rapid current limit function can reduce the inverter's overcurrent faults at maximum,
guaranteeing uninterrupted running of the inverter.

However, long-time rapid current limit may cause the inverter to overheat, which is not allowed. If
so, the inverter will output 40=E.CbC, indicating the inverter is overloaded and needs to stop.

 5 Fault and solutions

5.1 Alarms and solutions

provides a total of 51 fault information and protective functions. After a fault occurs, the inverter
implements the protection function, and displays the fault code on the keyboard (if the keyboard is
available).

Before contacting for technical support, you can first determine the fault type, analyze the causes,
and perform troubleshooting according to the following tables. If the fault cannot be rectified,
contact the official distributor directly.

22=E.HArd is the inverter hardware over-current or over-voltage signal. In most situations,

 6 Repair and maintenance
6.1 Routine maintenance
The influence of the ambient temperature, humidity, dust and vibration will cause the aging of
the devices in the Inverter, which may cause potential faults or reduce the service life of the
Inverter. Therefore, it is necessary to carry out routine and periodic maintenance. Routine
maintenance involves checking:

 7 MODBUS communication protocol
7.1 Communication protocol
7.1.1 Protocol content
The serial communication protocol defines the information content and the use of serial
communication transmission format, including: Host polling (or broadcast) format; host encoding
method, including: action-requiring function code, data transfer & error correction; mortem response
from the slave is the same structure, including: action confirmation, return data & error checking, etc.
If an error occurs when the slave receives information, or host requested action cannot be completed,
it will organize a fault as a feedback information to the host.

Application mode:
Inverter joins RS232/RS485 fieldbus compatible master-slavery PC/PLC control network.

Fieldbus structure:
(1) Interface mode
RS232/RS485 hardware interface

(2) Transmission mode

Asynchronous serial, half-duplex transmission mode. At the same time there can be only one
master slave transmit data while the other can only receive data. Data on the serial asynchronous
communication, is in the form of packets sent frame by frame.

(3) Topological structure:

Single master multi-slave system. Slave address setting range is 1 to 247, 0 is broadcast
communication address. Network slave address must be unique.

7.1.2 Protocol

D-100 series inverter is an asynchronous serial communication Modbus master-slave communication

protocol. Only one device on the network (host) can establish an agreement (called "query/command").
Other devices (slave) can only respond to the host's "query/command" by providing data, or take
actions according to the host's "query/command". The host can be personal computer (PC), industrial
control equipment or a programmable logic controller (PLC); slave is D-100 inverter. Host can
communicate to an independent slave machine, or can broadcast information to all slaves. For
independent host "query/command", slave returns information (known as the response). For broadcast
information, slave no need to send response to the host.

D-100 series inverter Modbus data communication protocol format is as follows: using RTU mode,
sending a message must start with an at least 3.5 characters’ interval time.

Transmittable characters are hexadecimal 0 ... 9, A... F. Network equipment keeps on detecting
network bus, including interval time. When the first domain (address field) is received, each device
decodes to determine whether it is sending to themselves. After the last transmitted characters, a pause
of at least 3.5-character time marks ending the message. A new message can start after this pause.

Whole message must be transmitted as a continuous stream. If there is a pause time over 1.5 a character
before completion, receiver will refresh and assumes that next byte is address domain of a new
message. Also, if a new message starts within a time interval of less than 3.5 character after

-99-
previous message, receiver will regard the new message as continuation of previous message. This
will lead to an error, because at last the CRC domain value will be wrong.

RTU frame format:

7.2 Verification mode
CRC mode: CRC (Cyclical Redundancy Check) uses RTU frame format message, including
error detection method based on CRC fields. CRC field detects the entire contents of the message.
CRC field includes two bytes, and contains a 16-bit binary value. It adds to the message after
calculations from the transmission equipment. The receiver recalculates the received C RC messages,
and compares with CRC value in the domain. If the two CRC values do not equal, then the
transmission has errors.

CRC firstly deposits 0xFFFF, then calls a consecutive 8-bit bytes in the message and processes
with the value currently in the registry. Only 8-bit data from each character is valid for CRC; start and
stop bits, and parity bit are invalid.

In CRC process, each 8-bit word XOR with registry separately. The result moves to the lowest
valid place. Highest valid place is 0. If LSB is 1, registry value will XOR with preset values separately;
if LSB is 0, then not execute. The whole process will repeat 8 times. When the last one (8th bit)
completes, next 8-bit byte will start XOR with current value. CRC value is the value in the registry
after all bytes are processed.

When adding CRC to a message, low byte adds first, then the high byte.

CRC calculation programs:

unsigned int cal_crc16 (unsigned char *data, unsigned int length)
{
unsigned int i, crc_result=0xffff;
while (length--)
{
crc_result^=*data++;
for (i=0; i<8; i++)
{
if (crc_result&0x01)
crc_result= (crc_result>>1) ^0xa001;
else
crc_result=crc_result>>1;
}
}
crc_result= ((crc_result&0xff) <<8) |
(crc_result>>8); return (crc_result);

7.3 Communication addresses
Function code address rules (EEPROM):

High place bytes: F0~FF (P0~PF), A0~AF (B0~BF) , 70~7F (D0~DF) .

Low place byte: 00~FF.

For example: P3.12, the address is expressed as F30C.

Note:
PF group: not readable or editable;
Group d: read-only and cannot be changed.

In addition, frequent EEPROM storage will reduce the life of the EEPROM. Some functions can be
realized by changing the value of RAM. User needs to change high place byte A to 4.
