SINAMICS G120 CU240B/E-2 Control Units List Manual (LH11), 01/2013
Description: Sets the signal source for the scaling of the lower torque limiting to limit the speed controller output without taking
into account the current and power limits.
Description: Sets the flux setpoint referred to rated motor flux.
Notice: A BICO interconnection to a parameter that belongs to a drive data set always acts on the effective data set.
Note: For p1570 > 100%, the flux setpoint increases as a function of the load from 100% (no-load operation) to the setting
in p1570 (above rated motor torque), if p1580 > 0% has been set.
Description: Sets the flux threshold value for enabling the speed setpoint and the end of magnetizing (r0056.4).
Note: The parameter only has an influence if the flux actual value reaches the threshold value p1573 more quickly during
magnetizing than the time set in p0346.
The parameter has no influence for flying restart (see p1200) and after DC braking (see p1231).
Description: Sets a dynamic voltage reserve.
Dependency: Refer to: p0500
Note: In the field weakening range, it must be expected that the control dynamic performance is somewhat restricted due
to the limited possibilities of controlling/adjusting the voltage. This can be improved by increasing the voltage
reserve. Increasing the reserve reduces the steady-state maximum output voltage (r0071).
Description: Sets a dynamic voltage reserve.
Dependency: Refer to: p0500
