Note 1. Connect a surge absorber as close to the servo motor as possible.
2. There is no polarity in electromagnetic brake terminals (B1 and B2).
When fabricating the motor brake cable MR-BKS1CBL-
M-H, refer to section 11.1.4.
(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 brake cable should be within 2m long.
Refer to section 11.8 for the wire used for the extension cable.
