PARAMETERS
4.2.4 Multi-speed operation
(Pr. 4 to 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 = 3 or 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 key ( key when using the parameter unit (FR-PU04-MGI)) to store
the set frequency.
• Use any of Pr. 180 to Pr. 183 to assign the terminal used to input the REX signal.
