4. SIGNALS AND WIRING
(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 14.9 for the wire used for the extension cable.

Electromagnetic
brake 24VDC
power supply
Note 1. Connect a surge absorber as close to the servo motor as possible.
2. Use of the following connectors is recommended when ingress protection (IP65) is necessary.
Relay connector
a) Relay connector
for extension
cable
b) Relay connector
for
electromagnetic
brake cable
3. There is no polarity in electromagnetic brake terminals (B1 and B2).
4. Do not use the 24VDC interface power supply for the electromagnetic brake.
5. Shut off the circuit by interlocking with the emergency stop switch.
6. When using a servo motor with an electromagnetic brake, assign the electromagnetic brake interlock (MBR) to an external
output signal with parameters No.PD09 to PD11.
