MG.33.M2.02 - VLT
Function:
Sets the torque limit for generator mode operation. The torque
limit is active in the speed range up to the rated motor speed
(par. 1-25). See illustration for par. 4-16 as well as par. 14-25
for further details.
Function:
Sets the current limit for motor operation. To protect the motor
from reaching the stalling torque, the default setting is 1.6 x the
rated motor torque (calculated value). If a setting in par. 1-00
to par. 1-26 is changed, par. 4-16 to par. 4-18 are not auto-
matically reset to the default settings.
To obtain maximum output torque and prevent the motor from
stalling, it is recommendable
4-16 and 4-17 (Torque Limits)
Function:
Provides a final limit on the drive output frequency for improved
safety in applications where you want to avoid accidental over-
speeding. This limit is final in all configurations (independent of
the setting in par. 1-00).
Function:
Select an analog input for scaling the settings in par. 4-16 and
4-17 from 0% to 100% (or inverse). The signal levels corre-
sponding to 0% and 100% are defined in the analog input
scaling, e.g. par. group 6-1*. This parameter is only active when
