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 preset the running speeds in parameters and switch between them using terminals.
zAny speed can be selected by switching on-off the contact signal (RH, RM, RL or REX signal).
zBy using these functions with Pr. 15 "jog frequency", Pr. 1 "maximum frequency" and Pr. 2 "minimum
frequency", up to 18 speeds can be set.
zValid 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 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 to store the set
frequency. When using the FR-PU04 (option), press the key.)
• Use any of Pr. 180 to Pr. 186 to assign the terminal used to input the REX signal.

Factory Setting Setting Range Remarks
4 60Hz 0 to 400Hz
5 30Hz 0 to 400Hz
6 10Hz 0 to 400Hz
24 to 27 9999 0 to 400Hz, 9999 9999: Not selected
232 to 239 9999 0 to 400Hz, 9999 9999: Not selected
Note: 1. The priorities of the frequency commands are in order of jog, multi-speed operation, No. 4 terminal and
No. 2 terminal.
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 and Pr. 232 to Pr. 239 settings have no priority between them.
5. The parameter values can be changed during operation.
6. When 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.
7. When only the REX signal on and Pr. 232 = "9999", the set frequency is changed to the value of low
speed operation command (Pr. 6).
