17. SPEED CONTROL OPERATION
(b) Auto tuning response (parameter No.PA09)
If the machine hunts or generates large gear sound, decrease the set value. To improve performance,
such as shortening the settling time, increase the set value.

PA11 TLP Forward rotation torque limit 100.0 % 0 to 100.0
PA12 TLN Reverse rotation torque limit 100.0 % 0 to 100.0
You can limit the torque generated by the servo motor.
(a) Forward rotation torque limit (parameter No.PA11)
Set the parameter on the assumption that the maximum torque is 100 [%]. The parameter is for limiting
the torque of the servo motor in the CCW power running or CW regeneration. No torque is generated
when this parameter is set to "0.0".
(b) Reverse rotation torque limit (parameter No.PA12)
Set the parameter on the assumption that the maximum torque is 100 [%]. The parameter is for limiting
the torque of the servo motor in the CW power running or CCW regeneration. No torque is generated
when this parameter is set to "0.0".
