CW/CCW Deceleration Method and the Initial Origin Search
Direction
Parameters are provided to specify the CW/CCW deceleration method and
the initial origin search direction. This section provides information on these
settings.
Setting the CW/CCW
Deceleration Method
When a previous model of MC Unit receives a limit signal input during the ori-
gin search operation, reverse operation will start after the movement is
stopped by a counter pulse. It does not decelerate to a stop. As shown below,
with the CS1W-MC-421/221, it is possible to select whether reverse operation
will start after movement is stopped by a counter pulse, or it will be deceler-
ated to a stop.
Note
There is a sudden change in the speed when the MC Unit is stopped by the
counter pulse as shown below.
