4.2.36 Computer link operation (Pr. 117 to Pr. 124, Pr. 342)

Pr. 117 "communication station number"
Pr. 118 "communication speed"
Pr. 119 "stop bit length"
Pr. 120 "parity check presence/absence"
Pr. 121 "number of communication retries"
Pr. 122 "communication check time interval"
Pr. 123 "waiting time setting"
Pr. 124 "CR • LF presence/absence selection"
2
Pr. 342 "E PROM write selection"
Used to perform required settings for RS-485 communication between the inverter and
personal computer.
Using the inverter setup software (FR-SW"-SETUP-WE (or -WJ for Japanese
version)), parameter setting, monitoring, etc. can be done efficiently.
! ! ! ! The motor can be run from the PU connector of the inverter using RS-485
communication.
