2.12.5 Torque limitation
Via MCTRL_nLoMLim_a and MCTRL_nHiMLim_a you can set an external torque limitation. This
means that different torques can be selected for the quadrants "driving" and "braking".
·
MCTRL_nHiMLim_a is the upper torque limit in [%] of the max. possible torque.
·
MCTRL_nLoMLim_a is the lower torque limit in [%] of the max. possible torque.
·
The max. possible torque is set under C0057. ( ^ 2−49)
Stop!
Only set positive values in MCTRL_nHiMLim_a and negative values in MCTRL_nLoMLim_a,
otherwise the speed controller may be unable to perform its intended control function. This can result
in an uncontrolled acceleration of the drive.
Tip!
·
If MCTRL_nHiMLim_a is not assigned (free), the upper torque limit automatically is 100 % of
the max. possible torque.
·
If MCTRL_nLoMLim_a is not assigned (free), the lower torque limit automatically is −100 % of
the max. possible torque.
·
At quick stop (QSP) the torque limitation is deactivated, i.e. the drive is operated with ± 100 %.
