2.4.3 Multi-speed operation [Pr. 4 to 6, 24 to 27, 232 to 239]
Can be used to change the preset speed in the parameter
with the contact terminals.
Each speed can be selected by merely turning ON or OFF
the contact signals (RH, RM, RL, REX signals).
Refer to page 48 for the detail of input signal combinations.

(1) 3-speed setting [Pr. 4 to 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.
In the initial setting, if two or three signals 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.

Valid in the External operation mode [Pr. 79 = 0, 2] or PU/
external combined operation mode [Pr. 79 = 3, 4].
Multi-speed parameters can also be set in the PU or

(2) Multi-speed setting for 4 or more speeds
[Pr. 24 to 27, 232 to 239]
Frequency from 4 speed to 15 speed can be set
according to the combination of the RH, RM, RL and
REX signals. Set the running frequencies in [Pr. 24 to
27, 232 to 239] (In the initial value setting, speed 4 to
speed 15 are unavailable).
For the terminal used for REX signal input, set 8 in
any of [Pr. 178 to 189 input terminal function selection]
to assign the function.
