Frequency Setting By External Terminals; (Pr. 4 To Pr. 6, Pr. 24 To Pr. 27, Pr. 232 To Pr. 239); Multi-Speed Setting Operation - Mitsubishi Electric FR-F740 EC Instruction Manual

Parameter
6.5

Frequency setting by external terminals

Purpose
Make frequency setting by combina-
tion of terminals
Perform jog operation
Added compensation for multi-
speed setting and remote setting
Infinitely variable speed setting by
terminals
6.5.1

Multi-speed setting operation

(Pr. 4 to Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)

Can be used to change the preset speed in the parameter with the contact signals.
Any speed can be selected by merely turning on-off the contact signals (RH, RM, RL, REX
signals).
