• 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.

See I/O specs on page 4–6.

Operations and Monitoring

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 parameter 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 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 inputs ON to select desired Multi-speed. Display the value of F001 on the digital operator.

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

d.Press the STR key once to store the set frequency. When this occurs, F001 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.Repeat operations in 2. a) to 2. e) to set the frequency of other Multi-speeds. It can be set also by parameters A020 to A035 in the first procedure 1. a) to 1. d).
