Oper

and Monitor

ing

While using the multi-speed capability, you can monitor the current frequency with 
monitor function D_01 during each segment of a multi-speed operation.
There are two ways to program the speeds into the registers A_20 to A_35:

1. Standard keypad programming:

a. Select each parameter A_20 to A_35.

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.

2. Programming using the CF switches. Set the speed by following these steps:

a. Turn the Run command OFF (Stop Mode).

b. Turn each switch ON and set it to Multi-speed. Display the value of F_01 on the 

digital operator.

c. Set the desired output frequency by pressing the 

 and 

 keys.

d. Press the 

 key once to store the set frequency. When this occurs, F_01 

indicates the output frequency of Multi-speed n.

e. Press the 

 key once to confirm that the indication is the same as the set 

frequency.

f. Repeat operations in 2. a) to 2. e) to set the frequency of other Multi-speeds. It 

can be set also by parameters A_20 to A_35 in the first procedure 1. a) to 1. d).

C_01, C_02, C_03, C_04, 
C_05

F_01, A_01 = 02,
A_20 to A_35

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 A_04 high enough to allow that speed.
