4. Motor encoder pulse output
The information on the amount of movement can be sent to the host controller in the form of A and B phase
pulses from the servo driver.

6. Position complete output (INP)
The completion of positioning can be verified by the positioning complete output (INP).When the absolute
value of the positional deviation counter at the position control is equal to or below the positioning
complete
Range by the parameter, the output is ON. Presence and absence of positional command can be specified as
one of judgment conditions.

7. Command pulse prohibit (INH)
The command pulse input counting process can be forcibly terminated by using the command pulse inhibit
input signal (INH).When INH input is ON ,the servo driver ignores the command pulse ,disabling pulse
counting function.
