4.7 Frequency setting by external terminals

Purpose
Make frequency setting by
combination of terminals
Perform jog operation
Added compensation for multi-speed
setting and remote setting
Infinitely variable speed setting by
terminals
4.7.1

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 terminals.
Any speed can be selected by merely turning on-off the contact signals (RH, RM, RL, REX signals).
