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 = 0000 Hex
HIGH
PWE = 03E8 Hex - Data value 1000,
LOW
corresponding to 100 Hz, see conversion.
The response from the slave to the master will be:
* default setting ( ) display text
