4.2.29 Computer link operation (Pr. 117 to Pr. 124)

Pr. 117 "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"
Used to perform required settings for RS-485 communication between the inverter and
personal computer.
! The motor can be run from the PU connector of the inverter using RS-485
communication.
