Examples Of The Use Of Communication Commands - Toshiba Tosvert RS485 Instruction Manual

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
(PFA011770)
(PFA00C400)
<Binary mode>
Computer → Inverter
2F 50 FA 01 17 70 01
2F 50 FA 00 C4 00 3D
- To monitor the output frequency (during 60 Hz operation)
<ASCII mode>
Computer → Inverter
(RFD00)
<Binary mode>
Computer → Inverter
2F 52 FD 00 7E
- To monitor the status of the inverter
<ASCII mode>
Computer → Inverter
(RFD01)
<Binary mode>
Computer → Inverter
2F 52 FD 01 7F
- To check the trip code (when the inverter is tripped because of )
<ASCII mode>
Computer → Inverter
(RFC90)CR
<Binary mode>
Computer → Inverter
2F 52 FC 90 0D
Inverter → Computer
(PFA011770)
CR
(PFA00C400)
CR
Inverter → Computer
2F 50 FA 01 17 70 01
2F 50 FA 00 C4 00 3D
Inverter → Computer
(RFD001770)
CR
Inverter → Computer
2F 52 FD 00 17 70 05
Inverter → Computer
(rFD010003)
CR
Inverter → Computer
2F 72 FD 01 00 03 A2
...For details on trip codes, see "Trip code monitor" in 8.2, "Monitoring
from the computer." (18H = 24d "" trip status)
Inverter → Computer
(rFC900018)CR
Inverter → Computer
2F 72 FC 90 00 18 45
...Set the operation frequency to 60 Hz.
CR
(60 / 0.01 Hz = 6000 = 1770H)
...Set to "forward run" with commands and frequency
CR
instruction from the computer enabled.
...Set the operation frequency to 60 Hz.
CR
(60÷0.01Hz=6000=1770H)
...For details on statuses, see 8.2 "Monitoring from
CR
the computer." (Stop status, FL output status, trip
status (r command))
