GD200A series VFD Installation guidelines
-22-
Note:

Do not use an asymmetrically constructed motor cable. If there is a symmetrically constructed
grounding conductor in the motor cable in addition to the conductive shield, connect the
grounding conductor to the grounding terminal at the VFD and motor ends.

Braking resistor, braking unit and DC reactor are optional parts.

Route the motor cable, input power cable and control cables separately.

GD series VFDs cannot share the DC bus with CH series VFDs.

When sharing the DC bus, the VFDs must be the same in power and must be simultaneously
powered on or off.

In shared DC bus running mode, current balance on the VFD input side must be considered
during wiring, and equalizing reactors are recommended to be configured.

If the terminal is not appeared, the machine does not provide the terminal as the external
terminal.
4.3.3 Wiring of terminals in main circuit
1. Connect the ground line of input power cable to the ground terminal (PE) of VFD directly, and
connect 3PH input cable to R, S and T and fasten up.
2. Connect the ground line of motor cable to the ground terminal of the VFD, and connect the 3PH
motor cable to U, V, W and fasten up.
3. Connect the brake resistor which carries cables to the designated position.
4. Fasten up all the cables on the outside of the VFD if allowed.
