Mode Description
Independent mode This mode is used for positioning.
Operation stops automatically when the preset num-
ber of pulses has been output. It is also possible to
stop the pulse output early with INI(880).
Continuous mode This mode is used for speed control.
The pulse output will continue until it is stopped by
executing another instruction or switching the PLC to
PROGRAM mode.
