Fine adjustment for torque control
2.5 Fine adjustment for torque control
Current loop gain parameter for adjusting torque control operation state is available with the FR-V500 series. Stable
operation is possible with the factory-set parameter.
Refer to the next page and adjust the parameters when torque pulsation or any other unfavorable phenomenon
occurs depending on the machine and operating conditions or when you want to exhibit the best performance that
matches the machine.
