_TCON – Torque control
365-TCAVM - Threshold value for actual torque monitoring
Source: Torque Control Actual Value Maximum
Function: Maximum value (threshold value) of actual torque monitoring.
When the threshold value is exceeded an output OSxx is set, provided the output has been
assigned the TCAVM function with the function selector FOSxx.

351-TCG - Torque controller gain
Source: Torque Controller Gain
Function: Gain of the torque controller (P-component)
353-TCMMX - Torque limit of torque controller
Source: Torque Controller Torque [M] Maximum
Function: Torque limit of the torque controller

Nm R1W3 DRIVE FLOAT32
Note:
The torque limit is active in all control modes. Generally the torque limit should be set
by the servocontroller, since the maximum torque of the motor MOMMX may be
around five times the nominal torque. The servocontroller is limited to twice its rated
current, however.
The parameter must be set specific to application!
Note:
The quadratic mean (RMS) of the torque should be less than or equal to the nominal
torque of the motor MOMNM within a clock cycle!
Note:
Continuous scaling of the torque limitation from 0 to 100 % is possible with the
SCALE function\ by way of an analog input.
