6.2.11.1 Torque limits
For the axis, static torque limits can be defined which are active in normal operation. They are
defined via the parameters:
•
Positive torque limit
4
0x500A:128
• Negative torque limit
4
0x500A:129
The torque limits can be deactivated in the technology application and can be replaced by
alternative torque limits.
The alternative torque limits are configured in the technology application via a control word in
the inverter and in the controller-based automation via the function block L_MC1P_SetTor-
queLimit.
If the set torque limits were changed in the technology application, this will be displayed in
the Status word parameter in bit 20.

The torque limits currently effective in the drive are displayed in the parameters Positive tor-
que limit and Negative torque limit.

The rated motor torque to be set here serves as a reference value for
different parameters with a setting/display of a torque value in percent.
Example:
•
Motor rated torque = 1.65 Nm
•
Max torque 0x6072 = 250 % Motor rated torque = 4.125 Nm
