bit2. Up-to-speed (US)
This signal turns ON when the start command signal (forward run, reverse run) is ON, and the
motor speed has reached a range of ±15% (standard value) of the speed command value. This
signal turns OFF when the start command signal turns OFF. The up-to-speed output range can be
set with the parameter SP048 (SUT). Even though the setting value is small, the output will be
±45r/min. Pay attention when speed command value is small.
