Frequency
Dividing Ratio

Any

Signal allocation can
be modified

Servo ON, P control (or Control Mode switching, forward/reverse motor
rotation by internal speed setting, zero clamping, reference pulse prohibited),
forward run prohibited (P-OT), reverse run prohibited (N-OT), alarm reset,
forward current limit, and reverse current limit (or internal speed selection)

Fixed Output

Servo alarm, 3-bit alarm codes

I/O

Signa

Sequen

Signal allocation
can be modified

Positioning completed (speed coincidence), during servomotor rotation, servo
ready, during current limiting, during speed limiting, brake released, warning,
selecting three of the NEAR signals

Dynamic Brake

Activated at main power OFF, servo alarm, servo OFF, or overtravel

Regeneration

External regenerative resistor

Overtravel Stop

Dynamic brake stops at P-OT or N-OT, deceleration to a stop, or free run to a
stop
