Pr.43
Analog Output Signal
Factory Setting: 00
Settings 00 Analog Frequency Meter (0 to Maximum Output Frequency)
01 Analog Current Meter (0 to 250% of the rated AC drive current)
02 Feedback Signal (0 - 100%)
03 Output Power (0 - 100%)
This parameter selects if the Output Frequency, Current, PID feedback or Output Power will be
the output signal on the AFM terminal (0 to 10V).
Pr.44
Analog Output Gain
Unit: 1%
Settings 00 to 200% Factory Setting: 100
This parameter sets the voltage range of the analog output signal on output terminal AFM.

The analog output voltage is directly proportional to the output frequency of the AC drive. A setting of
100% on Pr.44 makes the Maximum Output Frequency (Pr.03) of the AC drive to correspond to the
+10VDC analog voltage output. (The actual voltage is about +10VDC, and can be adjusted by Pr.44)
The analog output voltage is also directly proportional to the output current of the AC drive. A setting
of 100% on Pr.44 makes the 2.5 times rated current of the AC drive to correspond to the +10 VDC
analog voltage output. (The actual voltage is about +10 VDC, and can be adjusted by Pr.44)
Note: Any type of voltmeter can be used. If the meter reads full scale at a voltage less than 10 volts,
then Pr.44 should be set by the following formula:
Pr.44 = ((meter full scale voltage)/10)×100%
For Example: When using a meter with a full scale of 5 volts, adjust Pr.44 to 50%
