• After completing the wiring, check the connection status of each connector (such as cold
soldering of solder joints, short circuit of solder joints, improper pin sequence, etc.), press the
connector to make sure whether or not it is properly connected with the driver and whether or not
the screws are tightly fastened, and cannot have any conditions of cable damage, pulling or heavy
pressure, etc.
In particular, pay special attention to the polarity of the servo motor connection cable and the
encoder connection cable.
• Under normal conditions, it is not necessary to add external regenerative resistors, if there is a
need or doubt, please contact the dealer or manufacturer.
