Frequency Setting By Input Signals; Operation By Multi-Speed Operation (Pr. 4 To Pr. 6, Pr. 24 To Pr. 27) - Mitsubishi Electric 700 Series Instruction Manual

5.7

Frequency setting by input signals

Purpose
Make frequency setting by
combination of input signals
Infinitely variable speed setting by
input signals
5.7.1

Operation by multi-speed operation (Pr. 4 to Pr. 6, Pr. 24 to Pr. 27)

Use these parameters to change the speed to pre-set speeds using the RH, RM and RL signals. Speeds can be pre-set
using parameters.
A pre-set speed can be selected by simply turning ON/OFF the RH, RM and RL signals.

The above parameters allow their settings to be changed during operation in any operation mode even if "0" (initial value) is set in Pr. 77 Parameter write selection.
∗ These parameters can be set when Pr. 160 User group read selection = "0". (Refer to page 167)

REMARKS
For multi-speed setting, if two or three speeds are simultaneously selected, priority is given to the set frequency of the lower signal.
For example, when the RH and RM signals turn ON, the RM signal (Pr. 5) has a higher priority.
