Chapter 2 Installation and connection of servo driver
should be installed if the motor cable is longer than 100m. Refer to the following table for the carrier
frequency setting.
Length of cable between the
driver and motor
Less than 50m
Less than 100 m
More than 100m
Carrier frequency (PA.00)
Less than 15kHz
Less than 10kHz
Less than 5kHz
2.8.3 Grounding Wiring
The drive will produce leakage current. The higher the carrier frequency is, the larger the leakage
current will be. The leakage current of the driver system is more than 3.5mA, and the specific value of the
leakage current is determined by the application conditions. To ensure the safety, the driver and the motor
must be grounded.
The grounding resistance shall be less than 10ohm. For the grounding wire diameter requirement,
refer to 3.3 Models of main circuit peripheral devices.
Do not share grounding wire with the welding machine and other power equipment.
In the applications with more than 2 drivers, keep the grounding wire from forming a loop.

15 Noise current illustration
When the input noise filter is installed, the wire connecting the filter to the driver input power terminals
shall be as short as possible.
The filter enclosure and mounting cabinet shall be reliably connected in large area to reduce the back
flow impedance of the noise current Ig.
The wire connecting the driver and the motor shall be as short as possible. The motor cable adopts
4-core cable, with the grounding end grounded at the driver side, the other end connected to the motor
enclosure. The motor cable shall be sleeved into the metal tube.
