Note 1. Configure up the circuit so that power is switched off in the external sequence at servo alarm occurrence.
2. Terminals 13, 14 are N/O contact outputs. When the dynamic brake has stuck, terminals 13, 14 are opened. Therefore,
configure up the circuit to prevent servo-on in the external sequence.
