Input From Computer To Inverter - Mitsubishi Electric Fr-A5Nr Instruction Manual

4.4 Input from computer to inverter

(1) Operation commands
The following commands can be given:
FREQROL-A500(L)/FR-F500(L) Series
bit
Terminal name
0 AU
1 STF
2 STR
3 RL
4 RM
5 RH
6 RT
7 MRS
The terminal signals marked * are factory-setting. They can be changed using input terminal function
selection (Pr. 180 to). Input terminal function selection differ in function between inverters. For details,
refer to the Inverter Instruction Manual.
(2) Output frequency (Running speed)
Within the output range, the output frequency can be set for the FR-A500(L)/F500(L) series, and the run-
ning speed for the FR-V500 series.
REMARKS
• For the FR-A500(L)/F500(L) series, operation speed setting can be made by using Pr. 37 "speed display".
• For the FR-V500 series, the operation speed can be set in 0.1r/min increments when command code FF=1.
• The setting range of the set frequency differs according to inverters. Refer to the Inverter Instruction Manual for details.
(3) Inverter reset
The inverter can be reset from the computer.
