Functions
AM/AMI Adjustment
•Adjust the Inverter output gain according to the meters connected to the AM and AMI terminals.
Note: The offset data is set in %.
(Example) If AMI provides 4 to 20 mA output, the offset value is 20% (= 4/20). (Default value)
Operation Selection During Option Error
If the built-in optional board causes an error, you can set whether the Inverter trips or continues to
run regardless of the option error.
<Group H: Motor Control Parameters>
Offline Auto-Tuning Function
•This function enables measurement and automatic setting of the motor parameters required for
"sensorless vector control", "0-Hz sensorless vector control", and "sensor vector control".
•To perform "sensorless vector control", "0-Hz sensorless vector control", or "sensor vector control"
for a motor with unknown motor parameters, perform offline auto-tuning to determine the motor
parameters.
•To use the online auto-tuning function described later, be sure to perform offline auto-tuning in
advance.
•This function is applicable to 1st/2nd control, not to 3rd control.
•For motor parameters, the Inverter inputs data on one phase of Y-connection at 50 Hz.
