Defines the time needed to decelerate from 1000 to 0 rpm. The actual deceleration
time is proportional to the speed change (D n).

∆ n
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.
