9.5. Examples

9.5.1. Writing a parameter value
Change par. 4-14
Write the data in EEPROM.
PKE = E19E Hex - Write single word in par.
Motor Speed High Limit [Hz]
4-14
IND = 0000 Hex
PWEHIGH = 0000 Hex
PWELOW = 03E8 Hex - Data value 1000, cor-
responding to 100 Hz, see Conversion.
Note: Parameter 4-14 is a single word, and the
parameter command for write in EEPROM is
"E". Parameter number 414 is 19E in hexa-
decimal.
The response from the slave to the master will
be:
9.5.2. Reading a parameter value
Read the value in par. 3-41
PKE = 1155 Hex - Read parameter value in
par. 3-41
IND = 0000 Hex
PWEHIGH = 0000 Hex
PWELOW = 0000 Hex
If the value in par. 3-41
s, the response from the slave to the master
will be:
Motor Speed High Limit [Hz]
Ramp 1 Up Time.

Ramp 1 Up Time
NB!
3E8 Hex corresponds to 1000 decimal. The conversion index for par. 3-41 is -2, i.e.
0.01.
