Examples

Writing a parameter value
Change par. 4-14 Motor Speed High Limit [Hz] to 100 Hz.
Write the data in EEPROM.
PKE = E19E Hex - Write single word in par.
4-14 Motor Speed High Limit [Hz]
IND = 0000 Hex
PWEHIGH = 0000 Hex
PWELOW = 03E8 Hex - Data value 1000, corre-
sponding 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 hexadecimal.
The response from the slave to the master will be:
Reading a parameter value
Read the value in par. 3-41 Ramp 1 Up Time.
PKE = 1155 Hex - Read parameter value in par.
3-41 Ramp 1 Up Time
IND = 0000 Hex
PWEHIGH = 0000 Hex
PWELOW = 0000 Hex
If the value in par. 3-41 Ramp 1 Up Time is 10 s,
the response from the slave to the master will be:
NB!
3E8 Hex corresponds to 1000 decimal. The conversion index for par. 3-41 is -2, i.e. 0.01.
