SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Sets the smoothing time constant of the accelerating torque.
Note: The acceleration pre-control is inhibited if the smoothing is set to the maximum value.
Description: Displays the accelerating torque for pre-control of the speed controller.
Index: [0] = Unsmoothed
[1] = Smoothed
Dependency: Refer to: p0341, p0342, p1496
Description: Sets the fixed, upper torque limit.
Dependency: Refer to: p1521, r1538, r1539
Danger: Negative values when setting the upper torque limit (p1520 < 0) can result in the motor accelerating in an uncontrol-
lable fashion.
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: The torque limit is limited to 400% of the rated motor torque. When automatically calculating the motor/closed-loop
control parameters (p0340), the torque limit is set to match the current limit (p0640).
Description: Sets the fixed, lower torque limit.
Dependency: Refer to: p1520
Danger: Positive values when setting the lower torque limit (p1521 > 0) can result in the motor accelerating in an uncontrol-
lable fashion.
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: The torque limit is limited to 400% of the rated motor torque. When automatically calculating the motor/closed-loop
control parameters (p0340), the torque limit is set to match the current limit (p0640).
