SINAMICS G120 Control Units CU230P-2 Parameter Manual (LH9), 11/2009
Description: Sets the fixed, upper torque limit.
Dependency: Refer to: p1521, p1522, p1523, 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 (refer to p0340), the torque limit is set so that it matches the current limit p0640.
Description: Sets the fixed, lower torque limit.
Dependency: Refer to: p1520, p1522, p1523
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 (refer to p0340), the torque limit is set so that it matches the current limit p0640.
Description: Sets the signal source for the upper torque limit.
Dependency: Refer to: p1520, p1521, p1523
Danger: Negative values resulting from the signal source and scaling can cause the motor to accelerate in an uncontrolled
manner.
