6 Spindle Adjustment
MITSUBISHI CNC
(b) Adjusting deceleration time
Adjusts deceleration time in the same manner as acceleration time by using SP071 (variable current limit
during deceleration, lower limit value) and SP072 (variable current limit during deceleration, break point
speed).

Set SP071 and SP072
When SP071=100 is set, current limit during deceleration is
constant regardless of the speed. When setting SP071 to
100 or less and SP072 to maximum rotation speed or less,
deceleration time will be longer as current limit during
deceleration may be variable depending on the speed.
* Although a value more than 100 can be set to SP071,
basically, 100 or less should be set.
