Computer Link Operation (Pr. 117 To Pr. 124) - Mitsubishi Electric FR-F500 Instruction Manual

(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. 19 "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. The V/F 5-point flexible characteristic does not function when Pr. 60 is selected.
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.

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

Pr. 117 "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"
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.
The motor can be run from the PU connector of the inverter using RS-485 communication.
