Parameter 202
Output frequency high limit, f
MAX
is to
be changed to 100 Hz. This value must be remember
after a power failure, so it is written in EEPROM.
PKE =
E0CA Hex - Write to parameter 202
Output frequency high limit, f

PWE
HIGH
= 0000 Hex

The reply from the slave to the master will be:
10CA H 0000 H 0000 H 03E8 H
Example - Choice of a data value:
kW
[20] is to be selected in parameter 415
Process

. This value must be remembered after a power
failure, so it is written in EEPROM.
PKE =

is 10 seconds, the reply from the slave to the master
will be as follows:
