9.5 Examples
9.5.1 Writing a Parameter Value
Change parameter 4-14 Motor Speed High Limit [Hz] to 100 Hz.
Write the data in EEPROM.
PKE = E19E hex - Write single word in parameter 4-14 Motor Speed High Limit [Hz]:
l IND = 0000 hex.
l PWEHIGH = 0000 hex.
l PWELOW = 03E8 hex.
Data value 1000, corresponding to 100 Hz, see the chapter 9.4.12 Conversion.
The telegram looks like the Figure 57.
