PARAMETERS
117
4.2.36 Computer link operation (Pr. 117 to Pr. 124, Pr. 338 to Pr. 340, Pr. 342)
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"
Pr. 338 "operation command right"
Pr. 339 "speed command right"
Pr. 340 "link start mode selection"
Pr. 342 "E
2
PROM write selection"
Used to perform required settings for RS-485 communication between the inverter and
personal computer.
POINT
<To perform computer link operation>
!
Set "100, 101, 110 or 111" in Pr. 119 to make NET mode communication.
!
Presetting any value other than "0" in Pr. 122 enables communication between the
computer and inverter.
!
When the communication option is fitted, NET mode communication cannot be
used if "100, 101, 110 or 111" is set in Pr. 119.
!
When "1" is set in Pr. 340, the inverter is placed in the computer link operation
mode at power-on or inverter reset. (Note that it is overridden by the Pr. 79
"operation mode selection" setting.)
!
Refer to page 13 for wiring.
