Operation by multi-speed setting

Use these parameters to change among pre-set operation speeds with the terminals. The speeds are pre-set with
parameters.
Any speed can be selected by simply turning ON/OFF the contact signals (RH, RM, RL, and REX signals).

Multi-speed setting (Pr.4 to Pr.6)
• The inverter operates at frequencies set in Pr.4 when RH signal is ON, Pr.5 when RM signal is ON and Pr.6 when RL signal
is ON.

NOTE
• In the initial setting, when two or more of multi-speed settings are simultaneously selected, priority is given to the set
frequency of the lower signal.
For example, when RH and RM signals turn ON, RM signal (Pr.5) has a higher priority.
• The RH, RM and RL signals are assigned to the terminals RH, RM and RL in the initial status.
Set "0 (RL)", "1 (RM)", and "2 (RH)" in any of Pr.178 to Pr.189 (Input terminal function selection) to assign the signals to
other terminals.
