PARAMETERS
(2) Set the desired frequencies and voltages in Pr. 100 to Pr. 109.
•The setting must satisfy the following relationship: F1≠F2≠F3≠F4≠F5≠Pr. 3 "base frequency".
If the set frequencies are the same, a write error occurs.
If any frequency setting is "9999", its point is ignored.
4.2.41 Computer link operation (Pr. 117 to Pr. 124, Pr. 342)
Pr. 117 "communication station number"
Pr. 118 "communication speed"
Pr. 119 "stop bit length/data 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. 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.
zThe motor can be run from the PU connector of the inverter using RS-485 communication.
Communication specifications
Note: 1. The V/F 5-point flexible characteristic functions for V/F control only. It does not function for
advanced magnetic flux vector control.
2. These functions are activated only when "0" is set in Pr. 60.
3. The frequency voltage setting should be equal to or less than the Pr. 3 and Pr. 19 settings.
4. Pr. 19 must be set. (When Pr. 19 = "8888" or "9999", Pr. 71 cannot be set to "2" (5-point flexible
V/F characteristic).)
5. If "2" is set in Pr. 71, Pr. 47 and Pr. 113 do not function.
6. When "2" is set in Pr. 71, the electronic overcurrent protection is calculated for a standard motor.
