4-3-2 Speed coincidence output (V-COIN)
This signal is output when the motor speed is equal to the velocity specified by the velocity command. The motor
speed is judged to be coincident with the specified speed when the difference from the velocity command before/after
acceleration/deceleration is within the range specified by Pr 4.35 “Speed coincident range”

Set the speed coincidence (V-COIN) output detection timing. Output
the speed coincidence (V-COIN) when the difference between the
speed command and the motor speed is equal to or smaller than the
speed specified by this parameter.
The detection response has 10 r/min hysteresis.
*1) For parameter attribute, refer to Section 9-1.
*1 Because the speed coincidence detection is associated with 10 r/min hysteresis, actual detection range is as shown
below.
