(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 11.5 for the wire used for the extension cable.

3. There is no polarity in lock terminals (B1 and B2).
4. When using a servo motor with a lock, always assign the electromagnetic brake interlock (MBR) to CN1-pin 12 by
parameter No. PD18.
5. Do not use the 24VDC interface power supply for the lock.
6. Switch off the circuit interlocking with the emergency stop switch.
