Unexpected disturbance torque detection level
Unit of data : 0.01%
Valid data range : 0 to 10000
Standard setting value : 0
Specify the output level for the spindle unexpected disturbance
torque detection signal, using a percentage to the motor maximum
output torque. If this parameter is set to “0”, no spindle unexpected
disturbance torque detection signal is output.
