OMNUC G5-series (Pulse-train Input Type) AC Servomotors and Servo Drives User’s Manual
• Set the general-purpose output timing as rotation speed [r/min].
• The general-purpose output 1 (ZSP) turns ON when the motor speed is lower than the set value of 
this parameter.
• The set value of this parameter is valid in both forward and reverse directions, regardless of the 
actual motor rotation direction. This setting has a hysteresis of 10 r/min.
• The Speed Conformity Output signal will output if the speed command value matches the motor 
speed.
• This setting has a hysteresis of 10 r/min for detection.
