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.

CTB GH DRIVER

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.

GS DRIVER CTB

Figure 1-10 Derating curve of rated current of driver and altitude

Wiring of input side of the main circuit

Please pay attention to the following items for wiring of input side of the main circuit. See2-3

CTB GH DRIVER

Figure 2-3 Standard wiring diagram for incoming line

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 AC 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.

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 AC 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 AC servo driver. When cut off power of AC servo driver compulsorily with incoming line electromagnetic contactor, AC 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

● 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 GH AC servo driver of 37 to 75KW. 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. If external DC reactor is not connected, P1, P2 or D C + terminals shall be shorted as shown in Figure 2-5.

Figure 2-4 DC reactor connection diagram Figure 2-5 Connection diagram without DC reactor

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.
