Sequence Input Servo ON, P drive (or motor forward/reverse by torque control, zero-clamp drive reference, or
internal setting speed), forward run stop (P-OT), reverse run stop (N-OT), current limit + selection
(or internal speed selection), current limit − selection (or internal speed selection), alarm reset
Sequence Output Torque limit detection (or speed coincidence) , motor running output (or external brake interlock),
servo ready, servo alarm, 3-bit alarm codes
Dynamic Brake Operated at main power OFF, servo alarm or overtravel.
External Regenerative Unit Required when exceeding the allowable load inertia*

Overtravel Dynamic brake stop at P-OT or N-OT or deceleration stop
Protective Functions Overcurrent, overload, overvoltage, overspeed, reference input read error, overrun prevention,
origin error, CPU error, encoder error, fuse blown
