Note 1. Shut off the circuit on detection of the servo amplifier alarm.
2. Connect a surge absorber as close to the servo motor as possible.
3. There is no polarity in electromagnetic brake terminals (B1 and B2).
When fabricating the motor brake cable MR-BKS1CBL- M-H, refer to Section 12.1.4.
(2) When cable length exceeds 10m
When the cable length exceeds 10m, fabricate an extension cable as shown below on the customer side. In
this case, the motor power supply cable pulled from the servo motor should be within 2m long.
Refer to Section 12.8 for the wire used for the extension cable.
