7.3 Description of the tiinction code
Function code 00
The display can be prograznined after mains switch—on mains using
thls function code.
Data code
00: Display ot the rotational fieid frequency
01: Display of the motor current (R.~4.S.).
By pressing the SHIFT-key, either frequency or current display can ~e
selected during operation.
Functiori code 01, 02, 03
The inverter is set to one of the three prograininable rotational
tield frequencies, by olosing the switches S3 and/or S4. As soon
as S3 and/or S4 are closed, any other set—value setting is
made inactive.

The inverter is set to a fourth, programined rotational ffield
frequency by closing switch S5. As soon as S5 is closed,
any other set-value setting, as well as switches 53 and S4 are
inactive. The frequency is set in Hz. (Factory setting is 5 Hz).
Note:
At maximum ffrequencies higher than 50 or 60Hz, the rotational
field treguencies which are set usirig tunction codes 01, 02,
03 and 04 are multiplied according to the maximum freguencies.
