Note 1. Connect a surge absorber as close to the servo motor as possible.
2. There is no polarity in lock terminals (B1 and B2).
3. When using a servo motor with a lock, always assign the electromagnetic brake interlock (MBR) to
CN1-pin 12 by parameter No. PD18.
4. Do not use the 24VDC interface power supply for the lock.
5. Switch off the circuit interlocking with the emergency stop switch.
