6.19 Adjustment parameters
6.19.1 Calibration of analog outputs
H : Inclination characteristic of analog output
H : Bias of analog output
• Function
Output signals from FM terminals are analog voltage signals. Their standard setting range is from 0
to 7.5Vdc.
Using the FM (SW2) slide switch in the inverter, you can switch to 0-20mA output. Also, using these
parameters, you can calibrate the output to 4-20mAdc or 20-4mAdc.
Title Function Adjustment range Default setting
H
Inclination characteristic of
analog output 0: Negative inclination (downward slope)
1: Positive inclination (upward slope)

H Bias of analog output 0-100 (%) 0
Note: To switch to 0-20mAdc (4-20mAdc), turn the FM (SW2) slide switch to the I position.
■ Example of setting
H =1, H=0 H =1, H=20
H =0, H=100 H =0, H=100
+ The analog output inclination can be adjusted using the parameter HO.
