  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 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)
