11.3.6 Torques [350]
Menu with all parameters for torque settings.
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.
Communication information
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 maximum voltage increase is 25% of the
nominal output voltage. See Fig. 92.
Selecting “Automatic” will use the optimal value according
to the internal model of motor. “User-Defined” can be
selected when the start conditions of the application do not
change and a high starting torque is always required. A fixed
IxR Compensation value can be set in the menu [353].

NOTE: The Max Torque parameter will limit the maxmum
output current of the AC drive following the relation:
100% Tmot corresponds to 100% Imot.
The maximum possible setting for parameter 351 is
limited by Inom/Imot x 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.
NOTE: This menu is visible only in V/Hz mode.
