4.2.4 Multi-speed operation (Pr. 4 to Pr. 6, Pr. 24 to Pr.27)
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)"
Used to preset the running speeds in parameters and switch between them using terminals.
#
Any speed can be selected by switching on-off the contact signal (RH, RM, RL or REX signal).
#
By using these functions with jog frequency (Pr. 15), maximum frequency (Pr. 1) and minimum frequency
(Pr. 2), up to 10 speeds can be set.
#
Valid in the external operation mode or PU/external combined operation 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 120Hz 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 to store the set frequency.
When using the FR-PU04 (option), press the
WRITE
key.)
Note: 1. The multi-speed settings override the main speeds (across terminals 2-5, 4-5).
2. The multi-speeds can also be set in the PU or external operation mode.
3. For 3-speed setting, if two or three speeds are simultaneously selected, priority is given to the
frequency setting of the lower signal.
4. Pr. 24 to Pr. 27 settings have no priority between them.
5. The parameter values can be changed during operation.
6. When input terminal assignment is changed using Pr. 180 to Pr. 186, the other functions may be
affected. Check the functions of the corresponding terminals before making setting.
Pr. 1 "maximum frequency"
Pr. 2 "minimum frequency"
Pr. 15 "jog frequency"
Pr. 28 "multi-speed input
compensation"
Pr. 29 "acceleration/deceleration
pattern"
Pr. 79 "operation mode selection"
Pr. 180 to Pr. 186 (input terminal
function selection)
