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>
Computer → Inverter		Inverter → Computer
2F	50 FA 01 17 70 01	2F	50 FA 01 17 70 01
2F	50 FA 00 C4 00 3D	2F	50 FA 00 C4 00 3D

-To monitor the output frequency (during 60 Hz operation) <ASCII mode>

Computer → Inverter	Inverter → Computer
(RFD00)CR	(RFD001770)CR …Set the operation frequency to 60 Hz.
	(60⎟0.01Hz=6000=1770H)
<Binary mode>
Computer → Inverter	Inverter → Computer
2F 52 FD 00 7E	2F 52 FD 00 17 70 05

-To monitor the status of the inverter <ASCII mode>

Computer → Inverter	Inverter → Computer
(RFD01)CR	(rFD010003)CR	…For details on statuses, see 8.2 “Monitoring from
		the computer.” (Stop status, FL output status, trip
		status (r command))
<Binary mode>
Computer → Inverter	Inverter → Computer
2F 52 FD 01 7F	2F 72 FD 01 00 03 A2

- To check the trip code (when the inverter is tripped because of )

	…For details on trip codes, see “Trip code monitor” in 8.2, “Monitoring
	from the computer.” (18H = 24d “” trip status)
<ASCII mode>
Computer → Inverter	Inverter → Computer
(RFC90)CR	(rFC900018)CR
<Binary mode>
Computer → Inverter	Inverter → Computer
2F 52 FC 90 0D	2F 72 FC 90 00 18 45
