Operations
and Monitoring
4–11
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).
Valid for inputs:
C_01, C_02, C_03, C_04,
C_05
Required settings: F_01, A_01 = 02,
A_20 to A_35
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 A_04 high enough to allow that speed.
