13.20.3 Torque setpoint / additional torque setpoint
According to setting of MCTRL_bNMSwt_b, MCTRL_nMAdd_a serves as a torque setpoint
or as an additional torque setpoint.
Torque setpoint
At MCTRL_bNMSwt_b = TRUE, the speed control is active.
ƒ MCTRL_nMAdd_a acts as a torque setpoint.
ƒ The speed controllers carry out a monitoring function.
ƒ The torque setpoint is defined in [%] of the maximum possible torque.
– Negative values cause a torque in CCW rotation of the motor.
– Positive values cause a torque in CW rotation of the motor.
ƒ Set the maximum possible torque via C0057:

Additional torque setpoint
At MCTRL_bNMSwt_b = FALSE, the speed control is active.
ƒ MCTRL_nMAdd_a additionally acts on the output of the n controller.
ƒ The limits specified by the torque limitation MCTRL_nLoMLim_a and
MCTRL_nHiMLim_a thereby cannot be exceeded.
ƒ The additional torque setpoint can, for instance, be used for friction compensation
or acceleration feed forward (dv/dt).
