terminal
Two grounding terminals are respectively connected to the power
supply grounding terminal and the servo motor grounding terminal.
The entire system must be grounded.

Observe the following precautions when wiring the external regen resistor:
1. Do not directly connect the external regen resistor to the positive and negative poles of
.
Failure to comply will lead to damage of the servo drive or even cause a îš¿re.
2. Remove the jumper between
and D before using the external regen resistor. Failure to
comply will cause overcurrent trip and thus damage the braking tube.
3. For selection of external regen resistors, refer to section 1.4. Do not select any resistor
lower than the minimum resistance value. Otherwise, the servo drive will report Er201 or
be damaged.
4. Make sure that H02-25, H02-26 and H02-27 are accurately set before using the servo
drive.
5. Install the external regen resistor on incombustible matters (such as metal).
