Installation direction and space
● Installation spacing and distance requirements of single driver are shown in Figure 1-7.
● Generally, abreast installation mode is adopted when multiple drivers are installed in the control cabinet, and air inlet, outlet
and dedicated cooling fan shall be equipped; if up and down installation mode is adopted, stream guidance clapboard shall be
added between drivers to guarantee good cooling effect as shown in Figure 1-8.

Notes on motor and load
Compared with frequency conversion operation
GH 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.
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 3 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.
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.

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.
