4.5. Examples of the use of communication commands
Here are some examples of the use of communication commands provided for the VF-AS1 series of
inverters.
Inverter numbers and checksum used in ASCII mode are omitted from these examples.
Examples of communication
- To run the motor in forward direction with the frequency set to 60 Hz from the computer
<ASCII mode>
Computer Inverter Inverter
Computer
(PFA011770)CR (PFA011770)CR …Set the operation frequency to 60 Hz.
(60 / 0.01 Hz = 6000 = 1770H)
(PFA00C400)
CR (PFA00C400)CR …Set to “forward run” with commands and frequency
instruction from the computer enabled.
<Binary mode>
