How to Program
Some adjustable frequency drives have parameters
in w h ich you can write a text. To write a text
via the PWE block, set the parameter command
(AK) to "F" Hex. For a write command, the
text must have the shown format:
Data types supported by adjustable frequency drive:
Unsigned means that there is no operational
sign in the te leg ram.
Data types Description
3Integer16
4Integer32
5Unsigned8
6Unsigned16
7Unsigned32
9Textstring
10 Byte string
13 Time difference
33 Reserved
35 Bit sequence
Example - Write a parameter value:
Change par. 4-14 Motor Speed High Limit
to 100 Hz. After a mains failure, recall the
value to write it in EEPROM.
PKE = E19E Hex - Write for par. 4-14
Motor Speed High Limit
IND = 0000 Hex
PWE
HIGH
= 0 000 Hex
PWE
LOW
= 03E8 Hex - Data value 1000,
corresponding to 100 Hz, see conversion.
