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).
3. Do not use the 24 V DC interface power supply for the electromagnetic brake.
4. Create the circuit in order to shut off by interlocking with the emergency stop switch.
When fabricating the electromagnetic brake cable MR-BKS1CBL-_M-_, refer to section 5.5 and
5.6.
2) When cable length exceeds 10 m
Fabricate an extension cable as shown below. In addition, the electromagnetic brake cable
should be within 2 m.
Refer to section 4.3 for the wire used for the extension cable.
