Deceleration Time
Torque Limit
1070066022 - 101
Defines the time needed to decelerate from 1000 to 0 rpm. The actual
deceleration time is proportional to the speed change (

∆ 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.
