5.4 Group 3: Kimeneti Funkciók Paraméterezése

3 - 00 Analóg kimeneti Jel Factory Setting: d 0

Settings d 0 Analog frequency meter (0 to Maximum Output Frequency).

d 1 Analog current meter (0 to 250% of the rated AC drive

current).

! This parameter selects either Output Frequency or current to be displayed using the 0

to10V AFM output.

3 - 01 Analóg kimenet érték erősítése Factory Setting: d100

Settings d 1 to d 200% Unit: 1%

The parameter can be set during operation.

! The parameter sets the voltage range of the analog output signal at terminals AFM, that

corresponds with either the output frequency or the output current of the VFD.

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%.
