3-00Analog Output Signal (AFM)

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 (Pr.1-00) of the AC drive corresponds to +10VDC analog voltage output. (The actual voltage is about +10VDC, and can be adjusted by Pr.3-01).

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. 3-01)

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 Pr.3-01 should be set by the following formula: Pr.3-01 = ((meter full scale voltage)/10) ×100%

For example: When using the meter with full scale of 5 volts, adjust Pr.3-01 to 50%.
