While using the multi-speed capability, you can monitor the present frequency with
monitor function D001 during each segment of a multi-speed operation.
NOTE: When using the Multi-speed Select settings CF1 to CF4, do not display parame-
ter F001 or change the value of F001 while the inverter is in Run Mode (motor running).
If it is necessary to check the value of F001 during Run Mode, please monitor D001
instead of F001.
There are two ways to program the speeds into the registers A020 to A035:
1. Standard keypad programming:
a. Select each parameter A020 to A035.
b. Press the key to view the parameter value.
c. Use the and keys to edit the value.
d. Use the key to save the data to memory.

Valid for inputs:
C001, C002, C003, C004,
C005, C006
Required settings:
F001, A001 = 02,
A020 to A035
Notes:
•
When programming the multi-speed settings, be
sure to press the Store key each time and then set
the next multi-speed setting. Note that when the key
is not pressed, no data will be set.
•
When a multi-speed setting more than 50Hz(60Hz)
is to be set, it is necessary to program the maximum
frequency A004 high enough to allow that speed.
