109
(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.
Note: 1. The V/F 5-point flexible characteristic functions for V/F control only.
2. These functions are activated only when Pr. 60 = 0.
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 = "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.

Pr. 117 "station number"
Pr. 118 "communication speed"

LF presence/absence selection"
Used to perform required settings for RS-485 communication between the inverter and personal computer.
Using the inverter setup software (FR-SW0-SETUP-WE (or -WJ for Japanese version)), parameter setting,
monitoring, etc. can be done efficiently.
