Basic operation

The following describes the basic operation.
1.
After the drive contact is turned on, pulse output is started and the speed is increased from the bias speed.
2.
After the speed has reached the OPR speed, the operation will be performed at the OPR speed.
3.
After the near-point dog is detected, the speed is decreased.
4.
After the speed has reached the creep speed, the operation will be performed at the creep speed.
5.
After the near-point dog is turned from ON to OFF, pulse output is stopped when the zero signal is detected.
