Adjustment method (1): When the maximum load capacity matches the rated value
Use this function with the maximum gradient signal (100.0%).
Adjustment method (2): When the maximum load capacity is smaller than the rated value
* When the maximum load capacity can be output during adjustment
Step 1:
Minimize the gradient setting (0.0%) in advance to prevent a measured
load value from exceeding the maximum load capacity at power ON.
Step 2:
Adjust the gradient setting to output the maximum load capacity with the
maximum input signal.
Adjustment method (2”): When the maximum load capacity is smaller than the rated value
* When the maximum load capacity is not output during adjustment
Step 1:
Minimize the gradient setting (0.0%) in advance to prevent a measured
load value from exceeding the maximum load capacity at power ON.
Step 2:
Calculate the setting of the input signal (INmax) using the maximum
allowable output value (OUTmax).
INmax =
OUTmax
Rated value
× 100
Step 3:
Set the input signal to INmax(%).
Step 4:
Adjust the gradient signal so that the measured load value reaches
OUTmax.
Detection value adjustment function
The accuracy may decrease from the specifications according to the combination of the unit,
optional items, and load. When the conversion board is installed or replaced, be sure to adjust
detected values using this function.
Step 1: Set the feedback control as specified in “11.2.2 Feedback control.”
Step 2: Continue operation until the output becomes stable.
※
It is recommended to maximize the input signal value to the extent possible.
Set it according to the load specifications.
Step 3: Select [F40*: ** gain adjustment] on the display panel.
The function code to select differs according to the feedback control method to be
used.
[F404: Current gain adjustment] for constant current control
[F405: Voltage gain adjustment] for constant voltage control
[F406: Power gain adjustment] for constant power control
Step 4: Enter the measured load value on the setting screen.
Step 5: Press the SAVE key. If the entered load value is within the correctable range, it is
corrected.
※
Correction is not performed correctly if [F0: Rated value] has not been set correctly.
※
Correction is not performed correctly for detected values that differ greatly from measured
values. Large differences may be caused by wrong settings. Review this section and the
setting of [F0: Rated value].
