List of Parameters
p1531[0...n] Power limit regenerative / P_max gen
Access level: 2
Can be changed: U, T
Units group: 14_5
Min
-100000.00 [kW]
Description: Sets the regenerative power limit.
Dependency: Refer to: r0206, p0500, p1530
Note: The power limit is limited to 300% of the rated motor power.
For power units without regenerative feedback into the line supply, the regenerative power limit is pre-set to 30% of
the motoring power limit p1530 and in the ratio rated drive converter power to rated motor power.
For power units with energy recovery, the parameter is limited to the negative value of r0206[2].
r1533 Current limit torque-generating total / Iq_max total
Access level: 3
Can be changed: -
Units group: 6_2
Min
- [Arms]
Description: Displays the maximum torque/force generating current as a result if all current limits.
r1536 Current limit maximum torque-generating current / Isq_max
Access level: 4
Can be changed: -
Units group: 6_2
Min
- [Arms]
Description: Displays the maximum limit for the torque-generating current component.
r1537 Current limit minimum torque-generating current / Isq_min
Access level: 4
Can be changed: -
Units group: 6_2
Min
- [Arms]
Description: Displays the minimum limit for the torque-generating current component.
r1538 CO: Upper effective torque limit / M_max upper eff
Access level: 2
Can be changed: -
Units group: 7_1
Min
- [Nm]
Description: Displays the currently effective upper torque limit.
Note: The effective upper torque limit is reduced with respect to the selected upper torque limit p1520, if the current limit
p0640 is reduced or the rated magnetizing current of the induction motor p0320 is increased.
This may be the case for rotating measurements (see p1960).
The torque limit p1520 can be re-calculated using p0340 = 1, 3 or 5.
