Maximum Torque [351]
Sets the maximum motor torque (according to menu group Motor Data [220]).
This Maximum Torque operates as an upper torque limit. A Speed Reference
is always necessary to run the motor.

100% Torque means: I

MOT
. The maximum depends on the motor
current and VSD max current settings, but the absolute maximum adjustment
is 400%. The maximum possible setting for parameter [351] is limited by
Inom/Imot * 120% but not higher than 400%.
Note
The power loss in the motor will increase by the square of the torque when
operating above 100%. 400% torque will result in 1600% power loss, which
will increase the motor temperature very quickly.
IxR Compensation [352]
This function compensates for the drop in voltage over different resistances
such as (very) long motor cables, chokes and motor stator by increasing the
output voltage at a constant frequency. IxR Compensation is most important
at low frequencies and is used to obtain a higher starting torque. The maxi-
mum voltage increase is 25% of the nominal output voltage. See Fig. 78.
