Safety Information and Precautions MD500 User Manual

General Precautions
1. Requirements of a residual current device (RCD)

7KH$&GULYHJHQHUDWHVKLJKOHDNDJHFXUUHQWGXULQJUXQQLQJZKLFKÁRZVWKURXJKWKHSURWHFWLYHHDUWKLQJ 3( FRQGXFWRU
Thus install a type-B RCD at primary side of the power supply. When selecting the RCD, you should consider the transient and
steady-state leakage current to ground that may be generated at startup and during running of the AC drive. You can select a
specialized RCD with the function of suppressing high harmonics or a general-purpose RCD of 300 mA ( I 'n is two to four
times of protective conductor current).

2. Motor insulation test

ƕ %HIRUHWKHPRWRULVXVHGIRUWKHÀUVWWLPH

ƕ When the motor is reused after being stored for a long time

ƕ During regular maintenance checks.

This precaution detects poor insulation of the motor windings so that early actions can be taken to prevent damage to
the AC drive. The motor must be disconnected from the AC drive during the insulation test. A 500 volt insulation tester is
recommended for this test, and the insulation resistance must not be less than 5 M.

operation panel of the AC drive or install a thermal relay in the motor circuit for protection. It is especially important to take
this precaution if the AC drive has a higher power rating than the motor.

4. Running at frequency higher than 50 Hz

The MD500 AC drive can output frequency in the range 0 to 500 Hz. If it is necessary to operate the MD500 AC drive at
frequency higher than 50 Hz, consider the capacity of the machine.

5. Vibration of the mechanical device

The AC drive might experience mechanical resonance at some output frequencies. It is possible to avoid this by selecting the
MXPSIUHTXHQF\

6. Motor heat and noise

The output from the MD380 AC Drive is a pulse width modulation (PWM) waveform, which contains harmonic frequencies.
Because of this, the motor temperature, noise and vibration increase slightly when the AC drive operates at the line frequency
(50 Hz).

MD500 User Manual Safety Information and Precautions

7. Voltage-sensitive device or capacitor on the output side of the AC drive

Do not install a capacitor for improving power factor, or a voltage sensitive resistor for lightning protection, on the output side
of the AC drive. This is because the output is a PWM waveform and the AC drive might suffer transient overcurrent or become
damaged.

8. &RQWDFWRUDWWKH,2WHUPLQDORIWKH$&'ULYH

If there is a contactor installed between the input side of the AC drive and the power supply, DO NOT use it to start or to stop
the AC drive. However, if there is a real and urgent need to use the contactor to start or to stop the AC drive, make sure the
time interval between switching is at least one hour. If the interval between switching is shorter than one hour, this will reduce
the service life of the capacitor inside the AC drive.

If there is a contactor installed between the output side of the AC drive and the motor, do not switch off this contactor when
the AC drive is operating. Damage might occur to components inside the AC drive if you switch off the output contactor when
the AC drive is operating.

Safety Information and Precautions MD500 User Manual

10. Prohibition of three-phase input changed into two-phase input

Do not change a three-phase input of the AC drive into a two-phase input.

11. Surge suppressor

The AC drive has a built-in voltage-dependent resistor (VDR) for suppressing the surge voltage generated when the inductive
loads around the AC drive (for example the electromagnetic contactor, electromagnetic relay, solenoid valve, electromagnetic
coil and electromagnetic brake) are switched on or off.

If the inductive loads generate a very high surge voltage, use a surge suppressor for the inductive load and possibly also use
a diode.

Note
Do not connect the surge suppressor to the output side of the AC Drive.

12. Some special usages

If your installation requires special cabling that this user manual does not describe, for example to support a common DC bus,
contact Inovance for technical support and advice.

13. Disposal

do, the electrolytic capacitors might explode, and the plastic components will create poisonous gases. Treat any parts for
disposal as ordinary industrial waste.

14. Adaptable motor

ƕ The standard adaptable motor is an adaptable four-pole squirrelcage asynchronous induction motor. For other types of
motor, select the correct AC drive according to the rated motor current.

ƕ The cooling fan and rotor shaft of non-variable-frequency motors are coaxial, which results in reduced cooling effect

necessary to perform motor auto-tuning or to modify the default values based on actual conditions. Otherwise, the
running result and protection performance will be adversely affected.

ƕ The AC drive might cause an alarm or might be damaged when a short-circuit exists on cables or inside the motor.
Therefore, perform insulation short-circuit test when the motor and cables are newly installed or during routine
maintenance. During the test, disconnect the drive from the tested parts.

Ƶ Editing Function Parameters

This editing method is mostly used in on-site commissioning.

ƕ Pressing and in Level I menu is to quickly change the function parameter group.

ƕ Pressing and in Level II menu is to quickly increase or decrease the function parameter number.

ƕ Pressing and in Level III menu is to quickly increase or decrease the function parameter value. To save the setting,
press ENTER . To cancel the setting, press PRG .

4.4.2 Saving and Restoring Settings

After you change the value of any function parameter, the MD500 saves the new value locally so that it remains effective when you
next power on the AC drive. The MD500 also retains alarm information and cumulative running time statistics.

The MD500 allows you to make a separate external backup of parameter settings. This feature allows you to load a set of parameter
settings during commissioning, or to restore a set of parameter settings after completing a maintenance or repair operation on the
MD500.

You can also restore the default parameter settings, or clear the running data by using the function parameter FP-01. See ## for a
description of function code FP-01.

Before power on
Check voltage of power supply Bear in mind that if a higher voltage power supply than necessary is connected
to inverter, then inverter will probably get damaged instantly, for example 380V
SRZHUVXSSOLHVWRD9FODVVLQYHUWHUWKHQUHFWLÀHUEULGJHZLOOJHWEXUQW
So please check it before power on with a reliable instrument.
Check wirings If we wrongly connect power supply to inverter, then
of power supply and inverter outputs inverter will probably get damaged instantly.
If any one of inverter outputs keeps short-circuited to ground all
the way, then inverter may get damaged sooner or later, though
protective algorithm is planted inside. Motor windings being short-
circuited between phases or to ground may also be damaging.

The AC drive automatically starts another cycle after running one cycle, and will not stop until receiving the stop command.

FC-17 determines whether simple PLC is retentive at power down or when the AC drive stops.

If yes, the AC drive memorizes the PLC running stage and running frequency before power down or the AC drive stops and will
continue to run from the memorized stage at next power-on. If not, the AC drive restarts the PLC process at next power-on.

The purpose of the PID control is to keep the drive output frequency as close as possible to a desired reference via the PID
DGMXVWPHQW

ƕ Proportional gain (Kp1)

A large value tends to reduce the present error, but too large setting will cause system oscillation.

ƕ Integral time (Ti1)

The shorter the integral time is, the faster the error will be predicted. But too short setting will cause overshoot or system
oscillation.

ƕ Derivative time (Td1)

The longer the derivative time is, the faster the system will respond to the error. But too longer setting will cause vibration.

ƕ FA-03 = 0: Forward operation

When the PID feedback is smaller than the reference, the AC drive increases the output frequency. The winding tension control
requires forward PID operation.

ƕ FA-03 = 1: Reverse operation

When the PID feedback is smaller than the reference, the AC drive decreases the output frequency. The unwinding tension
control requires reverse PID operation.

FA-04: It is a non-dimensional parameter and is used for calculate the display of PID reference (U0-15) and PID feedback (U0-16).

ƕ U0-15 = PID reference (percentage) x FA-04

ƕ U0-16 = PID feedback (percentage) x FA-04

For example, if FA-04 is set to 2000 and PID reference is 100.0%, the display of PID reference (U0-15) is 2000.

FA-08 sets the limit of the negative PID output (the AC drive runs in the reverse direction) because too high negative PID output is

To catch a spinning motor, the AC drive detects the speed and direction of the spinning motor, and then starts to run from the
spinning motor frequency, minimizing impact of power supply to the motor.

It is applicable to the restart upon instantaneous power down of large-inertia load. In this start mode, ensure that the motor
parameters in group F1 are set correctly.

7.5.3 Overcurrent Stall Prevention

When the output current exceeds the value set in F3-18 during acceleration, running at constant speed or deceleration, the
overcurrent stall prevention function is enabled and the output frequency starts to drop. Until the output current recovers below
the stall prevention level, the output frequency starts to accelerate to the target frequency again.

In the high frequency area, the motor drive current is small and bigger motor speed drop is caused by stall current compared with
below the rated frequency. To improve the motor running characteristic, you can lower the overcurrent stall prevention level above

This helps to prevent problems such as big noise or too large mechanical stress caused by quick change of motor speed.

But in applications where rapid torque response is required, for example, two motors are used to drive the same load, you need to
set these two parameters to 0.00s.

For example, two motors drive the same load. To balance the load level the two motors, set one drive as the master in speed
control and set the other as the slave in torque control.

The slave will follow the output torque of the master as its torque reference, which requires quick response to the master output

7.6.6 Power Dip Ride-through

The power dip ride-through function ensures the system to run continuously at occurrence of momentary power down.

When an instantaneous power loss or a sudden power dip occurs, the AC drive compensates the DC bus voltage reduction with
the real-time energy feedback by reducing the output frequency, preventing the AC drive from stopping due to undervoltage.

7.7 Monitoring
The monitoring function enables you to view the AC drive state in the LED display area on the operation panel.

You can monitor the AC drive state in the following two ways:

1. View F7-03, F7-04 and F7-05 by pressing on the operation panel.

2. View parameters in group U0 via the operation panel

Ƶ View F7-03, F7-04 and F7-05 by Pressing the Shift Key

A maximum of 32 parameters in the running state can be viewed in F7-03 and F7-04. The display starts from the lowest bit of F7-03.
A total of 13 parameters in the stop can be viewed in F7-05.

If a parameter needs to be displayed during the running, set the corresponding bit to 1, convert the binary number to hexadecimal
equivalent, and set the related parameter to the hexadecimal number.

For example, to view the running frequency, bus voltage, output voltage, output current, output power and the PID reference, do as
follows:

1. Set bit 0, bit 2, bit 3, bit 4, bit 5 and bit 15 of F7-03 to 1 and convert the binary number 1000 0000 0011 1101 to the hexadecimal
number 803D.

Binary 1 0 0 0 0 0 0 0 0 0 1 1 1 1 0 1

Hexadecimal 8 0 3 D

2. Press the ENTER key on the operation panel.

The operation panel displays .

3. Press the PRG key twice on the operation panel.

The display of the operation panel starts from bit 0 (the lowest bit) in F7-03.

4. Press the key to view the running frequency, bus voltage, output voltage, output current, output power and the PID
reference.

You can view the other parameters in the same way.

7.8.6 Master and Slave Control

The master and slave control is designed for the multi-drive application, where the system is driven by multiple AC drives and the
motor shafts are coupled by gear, chain or conveyor belt.

The load is averagely allocated to the AC drives in the master and slave control mode. The external control signal need be
connected to the master only, and the master controls the slaves via serial communication.

The master must be in the speed control and the slaves follow the torque or speed reference of the master.

ƕ When the motor shafts are connected rigidly by chain or gear, the slaves must adopt the torque control mode to remove the
speed difference amongst the drives.

When the master and slaves are in the speed control, the droop rate must be used. See Figure-56.

Ƶ Droop Control
The droop control function aims at balancing the load level of two motors that drive the same load. This function is required only
when both master and slave are in speed control.

A proper droop rate is gradually obtained during the drive running. Therefore, do not set F8-15 to a very large value. Otherwise, the
steady speed will decline obviously when the load is very large. You must set this parameter in both master and slave.

7.10 Communication
MD500 supports the communication links, Modbus, PROFIBUS-DP, CANlink (always valid), or CANopen.

You can monitor and control of the AC drive, for example, view or modify the function parameters by using a host computer.

Make sure to set the communication parameters correctly. Otherwise, the communication may not be implemented.

7.10.1 Read and Write Function Parameters

Ƶ Read Function Parameters

For function parameters in groups F0 to FF and A0 to AF, the highest eight bits in the communication address indicate the function
code group, while the lowest eight bits indicate the hexadecimal number converted from the SN in the function code group.

For example, the communication address of F0-16 is F010H, in which F0H indicates function code group F0 and 10H is the
hexadecimal number converted from 16.

The communication address of AC-08 is AC08H, in which ACH indicates function code group AC and 08H is the hexadecimal
number converted from 8.

To read the desired function parameter, the host computer needs to send a read command to the AC drive. Here takes the Modbus
protocol as an example to describe the communication process of reading the drive data.

For example, to read F0-10, the read command is 01 03 F0 0A 01 DE D7 (hexadecimal). In the command,

ƕ 01H (settable): AC drive address

ƕ 03H: read command

ƕ F00AH: communication address of F0-10

ƕ 01H: number of function parameters

Ƶ Write Function Parameters

For function parameters in groups F0 to FF, the highest eight bits in the communication address indicate 00 to 0F or F0 to FF
according to whether to write the parameter to EEPROM, while the lowest eight bits indicate the hexadecimal number converted
from the SN in the function code group.

For example, the host computer writes data to F0-16. If not writing to EEPROM, the communication address is 0010H. If writing to
EEPROM, the communication address is F010H.

For function parameters in groups A0 to AF, the highest eight bits in the communication address indicate 40 to 4F or A0 to AF
according to whether to write the parameter to EEPROM, while the lowest eight bits indicate the hexadecimal number converted
from the SN in the function code group.

For example, the host computer writes data to AC-08. If not writing to EEPROM, the communication address is 4C08H. If writing to
EEPROM, the communication address is AC08H.

To write data, the host computer needs to send a write command to the AC drive. Here takes the Modbus protocol as an example
to describe the communication process of writing data to the AC drive.

For example, to write 2 to AC-16 (not writing to EEPROM), the write command is 01064C1000021F5E (hexadecimal). In the
command,

ƕ 01H (settable): AC drive address

ƕ 06H: write command

It is possible to change the sense, offset and scaling of the parameters on the analog outputs. This is by correcting the outputs
according to the formula:

Y = kX + b,

- 221 - efesotomasyon.com
8. Interfaces and Communication MD500 User Manual

Where:

ƕ Y = the output parameter after correction.

ƕ X = the output parameter before correction.

ƕ k = the scaling factor set by function code F5-11.

ƕ b = the offset set by function code F5-10.

Note that the scaling and offset values can be positive or negative.

Ƶ Use of PG Terminal
The closed-loop vector control (CLVC) mode with sensor, set by function code F0-01 = 1, helps to improve the stability and
accuracy of motor speed control. In this case it is necessary to install an encoder on the motor to provide the sensor input to the
PG card that the MD380 requires.

There are four versions of PG card to support the different encoder types:

ƕ Differential encoder

ƕ UVW encoder and wire-saving UVW encoder

ƕ Resolver

ƕ Open-collector encoder

The settings of encoder parameters F1-27 and F1-28 depend on the type of encoder used with the MD500. The following table
describes the function code settings for each of the encoder types.

8.2 Serial Communication

You must install the relevant extension card in the MD380 and set the correct value for function code F0-28 before you can use one
of the available serial communication protocols. The available serial communication protocols are:

ƕ RS485

ƕ PROFIBUS-DP

ƕ CANopen

ƕ CANlink

Note that function code F0-28 has the correct value for the CANlink communication protocol by default.

See the information about group Fd for instructions to set the hardware communication parameters for the relevant communication
protocol. You must set the identical communication rate and data format for

the MD500 and for the host computer, otherwise the serial communications will not work.

The MD500 serial port supports the Modbus-RTU slave communication protocol. This port supports the following functions:

ƕ Query and modify the MD500 function codes.

ƕ Query various running state parameters.

ƕ Send the Run command and the run frequency to the AC Drive from the host computer.

1. When parameter data is read by means of communication

For groups F0 to FF and A0 to AF, the high 16 bits of the communication address indicate the group number and the low 16
bits indicate the parameter number in the group.

Example:

The communication address of F0-16 is F010H, where F0H represents group F0 and 10H is the hexadecimal data format of
serial number 16 in the group.

The communication address of AC-08 is AC08H, where ACH represents group AC and 08H is the hexadecimal data format of
serial number 8 in the group.

2. When function code data is written by means of communication

For groups F0 to FF, whether the high 16 bits of the communication address are 00 to 0F or F0 to FF is decided by whether the
high 16 bits are written to EEPROM. The lower 16 bits indicate the function code number in the group.

Example:

F0-16: If it need not be written to EEPROM, the communication address is 0010H. If it needs to be written to EEPROM, the
communication address is F010H.

For groups A0 to AF, whether the high 16 bits of the communication address are 40 to 4F or A0 to AF is decided by whether the
high 16 bits are written to EEPROM. The lower 16 bits indicate the function code number in the group.

AC-08: If it need not be written to EEPROM, the communication address is 4C08H. If it needs to be written to EEPROM, the
communication address is AC08H.

8.5 Modbus Communication Protocol

The MD500 provides the RS485 communication interface and supports the Modbus-RTU communication protocol so that the user
can implement centralized control, such as setting running commands and function codes, and reading working status and fault
information of the AC drive, by using a PC or PLC.

8.5.2 Bus Structure

6. Interface mode

The RS485 extension card MD38TX1 must be inserted onto the AC drive.

7. Topological structure

The system consists of a single master and multiple slaves. In the network, each communication device has a unique slave
address. A device is the master (can be a PC, a PLC or an HMI) and initiates communication to perform parameter read or write
operations on slaves. The other devices (slaves) provide data to respond to the query or operations from the master. At the
same moment, either the master or the slave transmits data and the other can only receives data.

The address range of the slaves is 1 to 247, and 0 is the broadcast address. A slave address must be unique in the network.

8. Transmission mode

The asynchronous serial and half-duplex transmission mode is used. During asynchronous serial communication, data is sent
frame by frame in the form of message. In the Modbus-RTU protocol, an interval of at least 3.5-byte time marks the end of the
the previous message. A new message starts to be sent after this interval.

Ƶ Read and Written Parameters

Function parameters can be read and written (except the ones that cannot be changed because they are only for the factory use
or for monitoring).

The parameter group No. and parameter identifying No. are used to express the parameter address.

ƕ High-order bytes: F0 to FF (groups F), A0 to AF (groups A), 70 to 7F (group U)

ƕ Low-order bytes: 00 to FF

For example, to read parameter F3-12, the communication address of F3-12 is expressed as 0xF30C.

Note
ƕ Group FF: They are factory parameters. The parameters cannot be read or changed.
ƕ Group U: These parameters can only be read.

F0 to FE 0xF000 to 0xFEFF 0x0000 to 0x0EFF
A0 to AC 0xA000 to 0xACFF 0x4000 to 0x4CFF
U0 0x7000 to 0x70FF -

Frequent storage to the EEPROM reduces its service life. Therefore, in the communication mode, users can change the values of
certain function code parameters in the RAM rather than storing the setting.

ƕ For groups F parameters, users only need to change high order F of the function code address to 0.

ƕ For groups A parameters, users only need to change high order A of the function code address to 4.

The function code addresses are expressed as follows:

ƕ High-order bytes: 00 to 0F (groups F), 40 to 4F (groups A)

ƕ Low-order bytes: 00 to FF

For example, if function code F3-12 is not stored into EEPROM, the address is expressed as 030C; if function code A0-05 is not
stored into EEPROM, the address is expressed as 4005.

It is an invalid address when being read.

Users can also use the command code 07H to implement this function.

0: Broadcast address

This parameter is used to set the address of the AC drive. This address is unique (except the broadcast address), which is the
basis for point-to-point communication between the host computer and the AC drive.

When the local address is set to 0 (that is, the broadcast address), the AC drive can only receive and execute broadcast commands
of the host computer, but will not respond to the host computer.

Function Code Parameter Name Setting Range Default

Fd-03 Response delay 0 to 20 ms 2 ms

This parameter is used to set the delay from the time when AC drive receives the frame matching the local address to the time
when it AC drive starts returning a response frame. Too short response delay may make the host computer fail to receive the frame
in time. If the response delay is shorter than the system processing time, the system processing time shall prevail. If the response
delay is longer than the system processing time, the system sends data to the host computer only after the response delay is up.

Function Code Parameter Name Setting Range Default

Fd-04 Communication timeout 0.0s to 60.0s 0.0s

When the AC drive does not receive the communication signal within the time set in this parameter, it will report the
communication timeout fault (Err16).

When this parameter is set to 0.0s, the system does not detect communication timeout.

Generally, this parameter is set to 0.0s. In applications with continuous communication, you can use this parameter to monitor the

DANGER

To Prevent Electric Shock

ƕ Never wire the AC drive while the power is on.

ƕ Always keep the MCCB in the off state.

WARNING

To Prevent Overheating and Fire

ƕ When installing the drive inside the enclosed cabinet, use the cooling fan or air
conditioner to keep the air inlet temperature below 50°C.

CAUTION

To Prevent Damage to the Equipment

ƕ Cover the top of the drive with a temporary cloth or paper during installation so as to prevent foreign matter such as metal
shavings, oil and water from falling into the drive. After the installation is completed, remove the temporary cloth or paper.
ƕ Follow the proper electrostatic discharge (ESD) procedures when operating the AC

Ƶ Selection of Resistance of Regen Resistor

The AC drive transfers the regenerative energy generated during the braking of the motor to the externally mounted regen resistor.

$FFRUGLQJWRWKHIRUPXOD8[85 3E

ƕ U refers to the braking voltage at system stable braking.

ƕ The U value varies with the system. The 380 VAC system usually selects 700 V braking voltage.

ƕ Pb refers to the braking power.

Ƶ Selection of Power of Regen Resistor

In theory, the power of the regen resistor is the same as the braking power. But in consideration of de-rating, the power of the
regen resistor is calculated from the following formula:

K × Pr = Pb × D

ƕ K ranges from 15% to 30%.

ƕ Pr refers to the power of the regen resistor.

ƕ D refers to the braking frequency (percentage of the regenerative process to the whole deceleration).

Application Elevator Winding & unwinding Centrifuge Occasional braking load General Application

Braking Frequency 20% to 30% 20% to 30% 50% to 60% 5% 10%

Note
The preceding table is for reference only. You can select the resistance and power of the regen resistor based on
actual needs. However, the resistance must not be lower than the reference value. The power may be higher than the
reference value. Selection of the regen resistor model is determined by the generation power of the motor and is also

that can support the braking unit to operate continuously for long time.
ƕ Min. resistance supports the operating condition with braking frequency
of 10% and longest time for single braking of 10s.
ƕ The default initial braking voltage of the built-in braking unit is 780 V. The default initial braking voltage
of the MDBUN-60-T is 670 V, and that of the MDBUN-60-5T is 760 V. If the default initial braking voltage
is increased, the resistance value of corresponding regen resistor must also be increased.

Ƶ Terminal Wiring
1. Terminal wiring if the node has the CGND terminal

The MD38TX1 has three cables to connect the 485+, 485- and CGND terminals respectively. Check that the RS485 bus on site
has these three cables and the terminals are not connected reversely or wroingly.

If a shielded cable is used, the shield must also be connected to the CGND terminal. Except this CGND terminal, prevent the
shield from touching anywhere of the drive including the drive housing and the grounding terminal of the equipment.

Due to cable attenuation, if the connection length is larger than 3 m, use the AGW26 or a thicker cable. Always use a twisted
pair cable to connect 485+ and 485- respectively.

Non-shielded multi-core twisted pair cable and STP cable are recommended. If non-shielded multi-core twisted pair cable is
used, take the twisted pair to connect 485+ and 485- and twist the other unused cables into one rope and connect it to CGND.

If an STP cable is used, connect the twisted pair to 485+ and 485- respectively and the shield to CGND. The shield can be
connected to CGND only. It must not be connected to ground.

Take the following steps to handle it.

Step 1: Check whether a common reference ground of the 485 circuit exists on other ports of this node. If yes, connect the
CGND cable or the shield to the pin.

Step 2: Check whether the reference ground of the 485 circuit exists on the board of the node. If yes, connect the CGND cable
or the shield to it.

Step 3: If the reference ground of the 485 circuit is not found, keep the CGND cable or the shield unconnected and use an
extra ground cable to connect this node to the PE of other nodes.

10.2 De-rating
The drive can be operated at above the rated ambient temperature, altitude and default carrier frequency by de-rating the drive
capacity.

Ƶ Carrier Frequency De-rating

When the carrier frequency of the MD500 AC drive is increased above the default setting, you need to de-rate the drive's rated
output current according to the following table:

Power Carrier Frequency

Phd (kW) 3 kHz 4 kHz 5 kHz 6 kHz 7 kHz 8 kHz N+] 10 kHz 11 kHz 12 kHz

110 100.0%  84.4% 77.7% 71.3% 65.5% 60.4% 55.4% 51.1% 47.2%

Ƶ Ambient Temperature De-rating

The drive operation between -10°C to 40°C is normal without de-rating. Operation between 40°C and 50°C requires output current
de-rating. The rated output current must be de-rated for 1.5% per 1°C. The allowable maximum temperature is 50°C.

Ƶ Altitude De-rating
The MD500 AC drive must be de-rated for an installation altitude of above 1000 meters because the cooling effect available from
ambient air reduces. The rated output current must be de-rated for 1% per 100 meters. The maximum altitude is 3000 meters.

13.5.3 AC Output Reactor Installation

Whether to install an AC output reactor on the power output side is dependent on the actual situation. The cable connecting the
AC drive and the motor should not be too long; capacitance enlarges when an over-long cable is used and thus high-harmonics
current may be easily generated.

If the cable connecting the drive and the motor is equal to or longer than the value in the following table, connect an AC reactor on
the output side to suppress the high-harmonic current.

13.6 Breaker & Fuse Selection

The earth leakage current of the AC drive is larger than 3.5 A, requiring grounding protection.

The AC drive produces DC leakage current inside protective conductor, thus a B-type (delay-type) leakage breaker must be used.

When the leakage breaker acts accidentally, you can:

ƕ Use a leakage breaker of higher rated action current or use a delay-type leakage breaker.

ƕ Lower the carrier frequency of the AC drive.

ƕ Shorten the length of drive cables of the motor.

ƕ Take leakage current suppression measures.

The recommended leakage breaker manufacturers are CHINT and Schneider.

The following table is the selection guidance of the breaker, contactor and fuse.

2. It is recommended that all control cables be shielded.

3. It is recommended that the motor cables, power input cables and control cables be laid in different ducts. To avoid
electromagnetic interference caused by rapid change of the output voltage of the AC drive, the motor cables and other cables
must not be laid side by side for a long distance.

5. The power input and output cables of the AC drive and weak-current signal cables (such as control cable) should be laid
vertically (if possible) rather than in parallel.

6. The cable ducts must be in good connection and well grounded. Aluminium ducts can be used to improve electric potential.

13.8 Solutions to Current Leakage

The AC drive outputs high-speed pulse voltage, producing high-frequency leakage current during running of the AC drive. Each
AC drive produces more than 100 mA leakage current. Therefore, it is necessary to select a residual current circuit-breaker with
rated operating current of 100 mA above.

The AC drive generates DC leakage current in protective conductor. In this case, a time-delay B-type breaker must be used. If
multiple AC drives are required, each AC drive must be installed with a circuit-breaker.
