The following items shall be noted when selecting the installation environment:
1. Ambient temperature: operate in -10℃ ~ 45℃; if the ambient temperature is higher than
45℃, the equipment shall be used with 30% derating for each 5℃ temperature rise.
★ Note: If the ambient temperature is higher than 45 ℃ , the ventilation shall be
strengthened, and use by the specified derating.

Figure 1-7 Single controller installation Figure 1-8 Multiple controllers installation
Notes on motor and load
Compared with frequency conversion operation
GS DRIVER is full closed-loop vector servo driver. It adjusts output voltage and current
automatically according to the load change. It's more energy-efficient than inverter with
higher speed control accuracy and wider speed regulation range. As the controlled motor
and driver are closed loop, the control of position, speed and torque can be achieved
conveniently.
Constant torque operation
When motor works in constant torque area, the output torque of the motor is required by the
mechanical operation instead of the rated torque of the motor. However, the maximum
continuous output torque of the motor must not exceed the rated torque.
High-speed operation in constant power area
For high-speed operation in constant power area, the increased vibration and noise shall
be considered, and the service speed range of motor bearing and mechanical devices must
be confirmed, and consulted in advance. It's strictly prohibited to make the machine operate
above the rated speed.
GS DRIVER CTB
Lubrication of the mechanical device
For reduction box and gear head motor and other mechanical device that requires
lubrication, damage may be caused due to deterioration of lubricating effect in long-term
low-speed operation. It must be consulted in advance.
Negative torque load
Negative torque load occurs frequently for load such as lifting. The driver will generate
over-current and overvoltage alarm and trip. Equipping of brake components or mechanical
safety devices shall be considered.
Reciprocating load
Please pay attention to unstable phenomenon in output current when the driver is driving
piston reciprocating load. The phenomenon is more prominent in long-term low-frequency
operation. The capacity of driver shall be increased.
Mechanical resonance point of the load device
The driver may encounter the mechanical resonance point of the load device in certain
output frequency range. It can be avoided by setting jump frequency.
Notes on the driver
Applications not in rated voltage
The servo driver shall not be used in voltage that not in the working voltage range. Please
conduct voltage transformation with appropriate step-up or step-down unit as required.
Note on the drive phase input into 2-phase input
The device shall not be changed into 2-phase input, otherwise, default phase protection will
occur.
Capacitor or pressure-sensitive device to improve power factor
As shown in Figure 1-9, the output of the driver is PULSE wave, drive failure tripping or
damage to the device will be caused due to capacitor or pressure-sensitive device for
lightning to improve power factor installed at the output side. They must be removed.
GS DRIVER CTB
Figure 1-9 Capacitor is prohibited at the output end of controller
Lightning attack protection
lightning over-current device is equipped in the driver for self-protection to induction stroke
Altitude and derating operation
For areas with altitude over 1000 m, derating operation is necessary due to deterioration of
cooling effect of the drive caused by thin air. The relationship curve of rated current of driver
and altitude is shown in Figure 1-10.
Figure 1-10 Derating curve of rated current of driver and altitude
Notes on scrapping:
Explosion of electrolytic capacitor: the electrolytic capacitors on main circuit and printed
panel may explode when incinerated.
Plastic incineration waste gas: toxic gases will be generated in incineration of front panel
and other plastic parts.
Processing method: please process the waste as industrial waste.
★ Description: The contents of the manual are subject to change due to product upgrade
or optimize. The new version shall prevail.

Wiring of input side of the main circuit
Please pay attention to the following items for wiring of input side of the main circuit. See
Figure 2-3 for standard wiring.
Incoming line circuit breaker (MCCB)
The main circuit power input terminals (R, S, T) must be connected to 3-phase AC power
through line protection circuit breaker (MCCB).
● The selection of MCCB must be in accordance with requirements in Table 2-3.
●The time characteristics of MCCB must take overload characteristics (rated output current
200%/min) and time characteristics of the servo driver into account.
●Each servo driver shall be equipped with independent breaker; when multiple drivers
share a circuit breaker, to cut off the power supply and prevent the failure expansion during
driver failure, it's recommended to control the incoming line electromagnetic contactor with
the fault output relay of the driver to ensure safety.
GS DRIVER CTB
Installation of the residual current circuit breaker
The output of the servo driver is a high frequency PULSE wave so that there is
high-frequency leakage current generated. Residual current circuit breaker can be used at
the incoming line side of the driver to remove high-frequency leakage current, and only
inspect channel current that dangerous to human body. Please select special residual
current circuit breaker for servo (inverter) for wiring.
● When select special residual current circuit breaker, please select model for control of
one driver with an induction current over 30ma.
●When select normal residual current circuit breaker, please select model for control of one
driver with an induction current over 200ma, and a time over 0.1s.
●Installing isolation transformer between normal residual current circuit breaker and servo
driver can effectively avoid malfunction of the breaker.
Incoming line electromagnetic contactor
Incoming line electromagnetic contactor may be used to cut off the power in sequential
control. It cannot be used as start of servo driver. When cut off power of servo driver
compulsorily with incoming line electromagnetic contactor, servo driver is in power-off
alarm state, motor only can slide freely and stop.
● Frequent turning on/off incoming line magnetic contactor may cause heating, even
burning of charging resistor of the driver (driver interior).
● The time interval of turning on/off incoming line magnetic contactor shall be longer than
10 minutes.
AC reactor
Installing AC reactor at the incoming line side of the servo driver can effectively suppress
the surge of power, avoid burning of rectification part of the driver, and also can improve the
power factor of the power supply side. Please see Figure 2-3 for connection of AC reactor,
see Table 2-1 for selection of AC reactor.
DC reactor
External DC reactor can be connected to GS servo driver above 22KW. It can effectively
suppress the surge of power, avoid burning of rectification part of the driver, and also can
improve the power factor of the power supply side. Please see Figure 2-4 for connection of
DC reactor.
External DC reactor shall not be connected to GS servo driver lower than 15 KW. For GS
servo driver above 22KW without external DC reactor shall have P1, P2 or D C + terminals
shorted as shown in Figure 2-5.

Precautions for wiring of DC reactor
1. Please do not connect DC reactor to any main circuit terminal except P1, P2, otherwise,
it may cause internal short circuit of the driver, and burn the driver.
2. Please see Table 2-3 for specifications of DC driver connecting cable, the standard of
the main circuit cable.
3. Please see Table 2-1 for selection standard of DC reactor.
4. With external DC reactor, the P2 terminal shall be multiplex terminal, and one end of
braking resistor also shall be connected to the terminal.

Power side noise filter
In command to reduce high-frequency interference noise from power line coupling to the
driver, and suppress the noise feedback to power from the driver, noise filter with
appropriate model and specifications at the power input side of the driver.
Set and connect the incoming line filter correctly as shown in Figure 2-6.

The wiring of output side of main circuit
The output terminals of U, V, and W of the driver shall be connected to the connecting
terminals of U, V, and W of three-phase AC motor by correct phase sequence; if the phase
sequence is connected wrongly, the driver will raise the wrong phase sequence alarm with
an alarm number of E.PV. To solve the problem, exchange phase sequence of any two
phases. Please see Figure 2-8 for standard wiring of the output side.
