Operations and Monitoring

While using the multi-speed capability, you can monitor the current frequency with monitor function D01 during each segment of a multi-speed operation.

There are two ways to program the speeds into the registers A20 to A35:

1.Standard keypad programming:

a.Select each parameter A20 to A35.

b.Press the FUNC. key to view the parameter value.

c. Use the 1 and 2 keys to edit the value.

d. Use the STR 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 n. Display the data section of F01.

c. Set an optional output frequency by pressing the 1 and 2 keys.

d.Press the STR key once to store the set frequency. When this occurs, F01 indicates the output frequency of Multi-speed n.

e.Press the FUNC. key once to confirm that the indication is the same as the set frequency.

f.When you repeat operations in 2. a) to 2. e), the frequency of Multi-speed n can be set. It can be set also by parameters A20 to A35 in the first procedure 1. a) to 1. d).
