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 set for the quadrants ”driving” and ”braking”.
• MCTRL_nHiMLim_a is the max. torque limit in [%] of the max. possible torque.
• MCTRL_nLoMLim_a is the main. torque limit in [%] of the max. possible torque.
• The max. possible torque is set under C0057. (^ 2-43)
Stop!
In MCTRL_nHiMLim_a set only positive values, and in MCTRL_nLoMLim_a only negative values,
otherwise the speed controller may lose control. The drive may accelerate out of control.
Tip!
• If MCTRL_nHiMLim_a is not assigned, the max. torque limit is automatically 100 % of the
max. possible torque.
• If MCTRL_nLoMLim_a is not assigned, the min. torque limit is automatically -100 % of the
max. possible torque.
• At quick stop, the torque limitation is deactivated, i.e. the drive runs at ±100 %.
2.12.6 Maximum speed
The max. speed n
max
is set under C0011. This value is used as reference for the absolute and relative
setpoint selected for acceleration and deceleration times as well as for the max. and min. torque limit.
• n

only be made when the controller
is inhibited.

Tip!
MCTRL_nNmaxC11 Shows the max. speed set under C0011. (^ 2-44)
• Use this system variable for programming your own speed scalings.
• Example: C0011 = 3000 rpm ð MCTRL_nNmaxC11 = 3000
