4.2.4 Multi-speed operation
(Pr. 4, Pr. 5, Pr. 6, Pr. 24 to Pr. 27, Pr. 232 to Pr. 239)
Pr. 4 "multi-speed setting (high speed)"
Pr. 5 "multi-speed setting (middle speed)"
Pr. 6 "multi-speed setting (low speed)"
Pr. 24 to Pr. 27 "multi-speed setting
(speeds 4 to 7)"
Pr. 232 to Pr. 239 "multi-speed setting
(speeds 8 to 15)"
Used to switch between the predetermined running
speeds.
"
Any speed can be selected by merely switching
on/off the corresponding contact signals (RH, RM, RL, REX signals).
"
By using these functions with Pr. 1 "maximum
frequency" and Pr. 2 "minimum frequency", up to 17 speeds can be set.
"
Valid in the external operation mode or combined mode (Pr. 79 = 4).

<Setting>
!
Set the running frequencies in the corresponding parameters.
!
Each speed (frequency) can be set as desired between 0 and 400Hz during inverter operation.
After the required multi-speed setting parameter has been read, the setting can be
changed by pressing the
/ key. In this case, when you release the /
key, press the
SET
key (
WRITE
key when using the parameter unit (FR-PU04)) to store
the set frequency.
!
Use any of Pr. 180 to Pr. 183 to assign the terminal used to input the REX signal.
Pr. 1 "maximum frequency"
Pr. 2 "minimum frequency"
Pr. 29 "acceleration/deceleration
pattern"
Pr. 79 "operation mode
selection"
Pr. 180 to Pr. 183 (input terminal
function selection)
