Operation
Chapter Section Page Date
Defines the time needed to decelerate from 1000 to 0 rpm. The actual deceleration
time is proportional to the speed change (D n).
Adjustment Range: 0…320 s
Resolution: 0,01 s
Factory setting: 2,0 s
Customer setting ________ s

Example:
The drive should decelerate from 800 rpm to 300 rpm in 1 s.

Torque Limit
Adjusts the maximum permissible torque of the drive. The parameter can be influenced
by the analog torque limitation. During open-loop operation (CP.32 = 0) this
parameter has no function.
Adjustment Range: 0…5 x M
