GH DRIVER

Thank you for purchasing GH series servo driver produced by Beijing CTB Servo Co., Ltd. The GH series

AC servo driver is a high-quality, multi-functional and low-noise AC servo driver that was researched,

developed and manufactured by Beijing CTB Servo Co., Ltd. The driver is servo driver for AC induction

motor (IM) and AC permanent magnet synchronous motor (PM). It can control the position, speed,

acceleration and output torque of various AC servo motor appropriately.

In command to achieve control functions of various machine tools, GH series AC servo driver is

equipped with dual 32-bit CPU and abundant control function module. It can be conveniently

connected with various domestic and foreign CNC systems through standard control interfaces to

allow full play for function of CNC system. The characteristics of torque, acceleration and deceleration,

precision and efficiency of machine tool which is equipped with GH series AC servo driver are

remarkable, and accurate stop, C-axis, rigid tapping, electronic shift, multi-axis synchronization and

other functions can be realized easily.

As the ﬁrst choice of driving product of various machine tool power shaft, GH series AC servo driver can

be widely used for drive of product such as CNC milling machine, vertical machining center, horizontal

machining center, CNC boring machine, CNC lathe, vertical lathe, heavy horizontal lathe and gantry

machine tool.

For proper application, please read the manual carefully before using the GH series AC servo driver.

Abnormal operation, fault or reduction of service life, and even personal injury accident may be caused

by inappropriate use. Therefore, the manual shall be read repeatedly before use, and operate in

strict accordance with the instructions. The manual is attachment with the equipment. Please keep it

properly after using for future repair and maintenance of the driver.

Safety precautions

◆Installation

◆Wiring

◆Unpacking inspection

●For risk of injury, please do not install damaged or part missing driver.

●For risk of ﬁre, please install the equipment on nonﬂammable metal plate without

combustible materials around.

●Please be sure to tighten the mounting screws of the driver. Falling and damage of the

driver or personal injury may be caused by mounting screws loosing.

●Please do not install the equipment in environment with ﬂammable gas where an

explosion is caused easily.

●For risk of electric shock and ﬁre, please make sure that the input power supply is in

the OFF state before wiring.

●For risk of electric shock, the operation on main circuit terminal of the controller shall

be conducted after the power is cut off for ﬁve minutes, and the power charge

indicator CHARGE in the controller completely extinguished.

●For risk of electric shock and ﬁre, the wiring shall be carried by professional electrical

engineering personnel.

●For risk of electric shock and ﬁre, the ground terminal must be grounded reliably.

(earth resistance shall be lower than 4Ω)

●It’s prohibited to directly connect terminals of P / PB and N, or connect the zero line or

the earth wire to the N terminal. Otherwise, the rectiﬁer bridge will be shorted and the

main loop will be burned.

●It’s prohibited to connect the high-voltage line to control terminal of the driver.

Otherwise, the control board will be burned.

●For risk of injury, please set emergency stop and locking circuit at the outside of the

controller (user is responsible for the wiring) .

●There is a risk of electric shock and short circuit.

Caution

Danger

GH DRIVER

◆Wiring

◆Trial run

●For risk of injury and ﬁre, please ensure that the voltage of the main circuit AC input

power and the rated voltage of the driver are consistent.

●Please do not conduct withstand voltage and insulation test to the controller arbitrarily.

Otherwise, the semiconductor and other components in the controller may be damaged.

●For risk of ﬁre, please connect braking resistor and braking unit according to the wiring

diagram.

●Please do not connect the AC input power cord to the output U, V, W terminals.

Otherwise, damage to inside of the controller may be caused.

●For risk of ﬁre and malfunction of the controller, please tighten the terminals of main

loop and control circuit with appropriate torque.

●Please do not connect the phase shifting electrolytic capacitor and LC / RC noise ﬁlter

to the output circuit. Otherwise, damage to inside of the controller may be caused.

●Please do not connect the electromagnetic switch and electromagnetic contactor to

the output circuit to connect or disconnect the load. During loaded operation of the

controller, the surge current will cause protection circuit action of the controller.

●For risk of electric shock and short circuit, please do not touch the terminals of the main

circuit directly after power-on.

●Please conﬁrm the input and output signals to guarantee safe operation. Malfunction of

the system will cause casualties and damage to the work piece and nearby equipment.

●For risk of injury, alarm reset only can be done after ensuring that the operating signal

is cut off. Alarm reset with operating signal will lead to suddenly re-start.

●For risk of driver burning, the inside of long term stored driver shall be checked for

water and condensation.

●For risk of electric shock and burning the equipment, it’s prohibited to touch the

terminals of the driver with hand during operating.

●For risk of scalding, the running servo driver and motor may have a high temperature

rise, please do not touch.

●For risk of scalding and electric shock as the braking resistor has a high temperature

rise for discharging, please do not touch.

●For risk of damage to the equipment and accident, please do not change the settings

of the drive arbitrarily.

Caution

Danger

GH DRIVER

◆Maintenance and inspection

●For risk of electric shock, please do not directly touch terminals of the controller. Some

of them have high voltage and very dangerous.

●For risk of electric shock, please do install the housing before power-on; and must

disconnect the power ﬁrstly before removing the housing.

●For risk of electric shock and ﬁre, please conﬁrm that the power source is in the OFF

state or not before wiring.

●Inspection and maintenance only can be carried out after cut off the main circuit input

power and conﬁrm that the power charge indicator CHARGE completely extinguished.

There is a risk of electric shock as residual power in electrolytic capacitor.

●Please make designated professional electrical engineering personnel to conduct

inspection and maintenance. Before work, please take off metal object (watch, rings

etc.), and use tools with insulation protection during operation. Otherwise, it may cause

electric shock.

●For risk of explosion and ﬁre, used battery, circuit printing plate must not be throw into

ﬁre. Otherwise, it may cause explosion.

●CMOS IC integrated circuit is installed on main control panel. Full attention shall be

paid during operating. The electrostatic induction due to direct touching of ﬁnger on

the main control panel may cause damage to the main control panel.

●For risk of electric shock, please do not conduct wiring and removing terminal when

the equipment is energized.

●For risk of damage to the equipment, the appropriate parameter settings must be

carried out before running after control panel replacing.
