This user constant is used to set output timing of
positioning complete signal (COIN+, 1CN-25) to
be output when motor operation is complete after
a position reference pulse has been input.
Set the number of error pulses in terms of reference unit (the number of input pulses that
is defined using the electronic gear function).
If too large a value is set in this user constant, error may become too small when the mo-
tor runs at a low speed, causing COIN+ to be output continuously.
COINLV does not affect the final positioning accuracy.
3.7.4 Using Speed Coincidence Output Signal
1) This section describes how to wire and use contact output signal “speed coincidence out-
puts (LCT+, CLT-).” This signal is output to indicate that actual motor speed matches a
reference speed. The host controller uses this signal as an interlock.
