 Multi-speed setting (Pr.4 to Pr.6)
• The inverter operates at frequencies set in
the RL signal is ON.
Forward rotation start
Reverse rotation start
Middle speed
Switch
NOTE
• In the initial setting, if two or more speed switches (signals) are simultaneously turned ON, priority is given to the switch (signal)
for the lower speed. For example, when both RH and RM signals turn ON, the RM signal (Pr.5) has the 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.182 (Input terminal function selection) to assign the signals to other terminals.
