When the torque control, the motor speed in a limited speed range, interventional speed feedback, to reduce the
actual torque, so that the speed to limit within the scope of regression. Parameter Settings is smaller, the
greater the amount of feedback, the faster the adjustment, the smaller amount of speeding, but is too small
will fuel motor shaking; Parameter is set too large, adjust the slower, may have been speed, less than
the
speed limit. Actual speed will be slightly higher than the limit speed value.

To make SigOut effective TCMDreach signal output port, must meet the following conditions:
Condition 1: PC set torque instruction must be
within the error range of 1. Example: input torque command 80%, Pn208 set to 5%, internal drive
of input torque instruction in deceleration operation, when calculating the output torque of the
instructions within the scope of 75% ~ 85%, condition 1 is satisfied.
Condition 2: detect the actual motor torque and the difference between the input torque of the in
structions in the judgment error range within 2.
