DO4 and PRM33.)
Servo ON status output (Can be set with DO3 and
PRM46.)

with DO2 and PRM73.)
Sets to ON if accumulated pulses in deviation counter
are within ±value of PRM6 setting.
Turns on at servo-ON if command pulse inputs are
possible.
Turns off in emergency stop or if alarm occurs.
Internally connected to the ground terminal.
Internal signal ground terminal.
This is insulated from power supply (24G) for
sequence I/O signals.
Command pulse input terminal. Input voltage should
be 5V±10%.
3 command types selectable with PRM64 (Input type).
(1) Phase A / phase B input, (2) Pulse / code input,
(3) CW / CCW input
Outputs feedback pulses (Phase A, Phase B, Phase
Z, Phase ZM) as differential output.
* Phase ZM is output only when using the SRCP
series.
