(4) Data Change during the Movement
In the Half Direct Value Mode 1 to 3 and the Full Direct Value Mode, the change of any data set using
the output data register, out of the target position data, speed data, positioning width, and current limit
value during the pressing, during the movement is available. After changing the data, turn “ON” the
positioning command (DSTR) for more than tdpf.
Also, after turning “OFF” the DSTR, set aside some time for “twcsON + twcsOFF” or more, until the
next DSTR is turned “ON”.
The example is shows as follows, where the speed and acceleration/deceleration data items have been
changed.

Caution : 1. When the speed has not been set or it is set to “0”, the actuator is not moved, but an
alarm is not issued.
2. When the speed setting is changed to “0” during the movement, the actuator is
decelerated and stopped, but an alarm is not issued.
3. Even when the acceleration/deceleration data only is changed during the movement, the
setting of the target position data is required.
4. Even when the target position data only is changed during the movement, the setting of
the acceleration/deceleration data is required.
