Current Control - Mitsubishi Electric FR-XC-18.5K-PWM Instruction Manual

Parameter details
3.5.18
Current control (Pr.82 and Pr.83)
Use this function to control current output from the converter with harmonic suppression enabled as commanded.
Operation can be stable enough with these parameters in the initial setting, however, some adjustments may be required if
current vibration occurs depending on the power supply condition.

• Adjust the fluctuation range of current by setting Pr.82.
Increasing the setting value reduces the current fluctuation caused by external disturbance.
• Adjust the recovery time to the commanded current after a current fluctuation by setting Pr.83.
Increasing the setting value shortens the recovery time from the current fluctuation caused by external disturbance.
NOTE
• Setting Pr.82 too large makes the operation unstable.
• Setting only Pr.83 makes the operation unstable.
