Group 3: Output Function Parameters
Factory Setting: d0
Settings d0 Analog Frequency Meter (0 to Maximum Output Frequency)
d1 Analog Current Meter (0 to 250% of rated AC motor drive current) This parameter sets the function of the AFM output 0~+10VDC (ACM is common).
The voltage output type for this analog signal is PWM. It needs to read value by the movable coil meter and is not suitable for A/D signal conversion.

The analog output voltage is directly proportional to the output frequency of the AC drive. With the factory setting of 100%, the Maximum Output Frequency
The analog output voltage is directly proportional to the output current of the AC drive. With the factory setting of 100%, the 2.5 times rated current of the AC drive corresponds to +10VDC analog voltage output. (The actual voltage is about +10VDC, and can be adjusted by Pr.
NOTE
Voltmeter specification: The sourcing capability of the output is limited to 0.21mA. Sourcing voltage: 10V. Output resistance: 47kΩ.
If the meter reads full scale at a voltage less than 10 volts, then
For example: When using the meter with full scale of 5 volts, adjust
