PARAMETERS
5
Frequency setting by input signals
5.7 Frequency setting by input signals
5.7.1 Operation by multi-speed operation (Pr. 4 to Pr. 6, Pr. 24 to Pr. 27)
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)
Purpose Parameter that should be Set Refer to Page
Make frequency setting by
combination of input signals
Multi-speed operation Pr. 4 to Pr. 6, Pr. 24 to Pr. 27
111
Infinitely variable speed setting by
input signals
Remote setting function Pr. 59 113
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.

9999 0 to 400Hz, 9999
Frequency from speed 4 to speed 7 can
be set according to the combination of
the RH, RM and RL signals.
9999: not selected
25 ∗ Multi-speed setting (speed 5)
9999 0 to 400Hz, 9999
26 ∗ Multi-speed setting (speed 6)
9999 0 to 400Hz, 9999
27 ∗ Multi-speed setting (speed 7)
9999 0 to 400Hz, 9999
(1) Multi-speed setting for 3 speeds (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.

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.
