8 Command Reference
8.1.4 Deceleration Time Change (DCC)
8-20
(4) Programming Examples
DCC command programming examples are shown below.
• When bits 4 to 7 (Acceleration/deceleration degree unit selection) of OW 03 are set to
1 (ms).
The following example shows when the MOV command is executed to decelerate axis A1 from the rated
speed to 0 in four seconds, and when the MOV command is executed to decelerate the axis from the rated
speed to 0 in eight seconds.
* The unit of rated speed (min
-1
) must be converted to the same unit used for positioning speed (10
n
refer-
ence units/min).
