 V/f control with speed feedback slip compensation proportional gain
At first, adjust the proportional gain for speed feedback control.
• Check and gradually increase the set value of PG feedback value (3017Hex-11Hex).
• While checking the PG feedback value (3017Hex-11Hex), increase the value within the range
where the motor speed is stable.
• If the motor speed fluctuates or the motor vibrates wildly, decrease the set value until it becomes
stable.
• When adjusting the response if the load is actually activated, increase the set value to improve
response, or decrease the set value to make it stable.
 V/f control with speed feedback slip compensation integral time
Next, adjust the integral time for speed feedback control.
• Check and gradually decrease the set value of PG feedback value (3017Hex-11Hex).
• Decrease the value in the PG feedback value (3017Hex-11Hex) until it matches the reference
frequency.
• If the motor speed fluctuates or the motor vibrates wildly, increase the set value until it becomes
stable.
• When adjusting the response if the load is actually activated, decrease the set value to improve
response, or increase the set value to make it stable.
 Speed control limiter
Speed Control Slip Frequency Limit (3014Hex-47Hex) is the limiter for the slip frequency that is
added to the frequency reference. The maximum frequency is taken to be 100%. Ordinarily, leaving
this setting at 100% causes no problems.
