Programming
Example - Write a parameter value:
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
MAX
IND =
0000 Hex
PWE
HIGH
=
0000 Hex
PWE
LOW
03E8 Hex - Data value 1000,
corresponding to 100 Hz, see
Conversion
.
The reply from the slave to the master will be:
Example - Choice of a data value:
kW [20] is to be selected in parameter 415
Process
units
. This value must be remembered after a
power failure, so it is written in EEPROM.
PKE =
E19F Hex - Write to parameter 415
Process units
IND =
0000 Hex
PWE
HIGH
=
0000 Hex
PWE
LOW
0014 Hex - Choose data choice
kW
[20]
Svaret fra slaven til masteren vil være:
Example - Read a parameter value:
The value in parameter 206
Ramp-up time
is required.
The master sends the following inquiry:
PKE =
10CE Hex - read parameter 206
Ramp-up time
IND =
0000 Hex
PWE
HIGH
=
0000 Hex
PWE
LOW
0000 Hex
If the parameter value in parameter 206
Ramp-up
time
is 10 seconds, the reply from the slave to
the master will be as follows:
