Current control (Pr.82 and Pr.83)
• 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.
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.

Description
82
Current control proportional
gain
100%
0 to 200%
Set the proportional gain for the current
control.
Increasing the setting value reduces the
current fluctuation caused by external
disturbance.
83
Current control integral gain
100%
0 to 200%
Set the integral gain for the current control.
Increasing the setting value shortens the
recovery time from the current fluctuation
caused by external disturbance.
