How to calibrate the terminal AM when using the operation panel
The following example shows how to calibrate the maximum value of the AM terminal to the
50Hz output frequency. This operation is performed in PU mode.
Confirmation of the RUN indication and
operation mode indication
Press the MODE key to choose the parameter
setting mode.
Turn the digital dial until "C..." appears.
Press the SET key to show the currently set value.
The initial value "C---" appears.
Turn the digital dial until "C 1" appears.
Press the SET key to enable setting.
If the inverter is at a stop, press the RUN key to start
the inverter.
(Motor needs not be connected.)
Wait until the output frequency of 50Hz is reached.
Turn the digital dial to adjust the indicator needle
to the desired position.
(In contrast to the output analog current the value
shown for C1 does not change when turning the
digital dial.)
Press the SET key to set. Setting is complete.
By turning the digital dial, you can read another parameter.
Press the SET key to return to the "C---" indication (step
Press the SET key twice to show the next parameter (Pr.CL).

NOTES
Calibration can also be made for external operation. Set the frequency in external operation
mode, and make calibration in the above procedure.
Calibration can be made even during operation.
For the operation procedure using the parameter unit (FR-PU04/FR-PU07), refer to the
parameter unit instruction manual.
