p1520[0...n] CO: Torque limit upper / M_max upper
Access level: 2 Calculated:
CALC_MOD_LIM_REF
Data type: FloatingPoint32
Can be changed: T, U Scaling: p2003 Dynamic index: DDS, p0180
Unit group: 7_1 Unit selection: p0505 Function diagram: 6020, 6630
Min:
-1000000.00 [Nm] Max:
20000000.00 [Nm] Factory setting:
0.00 [Nm]
Description: Sets the fixed, upper torque limit.
Dependency: See also: p1521, p1522, p1523, r1538, r1539
DANGER
Negative values when setting the upper torque limit (p1520 < 0) can result in the motor accelerating in an
uncontrollable 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).
p1521[0...n] CO: Torque limit lower / M_max lower
Access level: 2 Calculated:
CALC_MOD_LIM_REF
Data type: FloatingPoint32
Can be changed: T, U Scaling: p2003 Dynamic index: DDS, p0180
Unit group: 7_1 Unit selection: p0505 Function diagram: 6020, 6630
Min:
-20000000.00 [Nm] Max:
1000000.00 [Nm] Factory setting:
0.00 [Nm]
Description: Sets the fixed, lower torque limit.
Dependency: See also: p1520, p1522, p1523
DANGER
Positive values when setting the lower torque limit (p1521 > 0) can result in the motor accelerating in an uncontrollable
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).
