11.5 Examples11.5.1 Writing a Parameter ValueChange par. 4-14Motor Speed High Limit [Hz] to 100 Hz.Write the data in EEPROM.PKE = E19E Hex - Write single word in par. 4-14Motor Speed High Limit[Hz]IND = 0000 HexPWEHIGH = 0000 HexPWELOW = 03E8 Hex - Data value 1000, corresponding to 100 Hz, seeConversion.The telegram will look like this:Note: par. 4-14Motor Speed High Limit [Hz] is a single word, and theparameter command for write in EEPROM is “E”. Parameter number 4-14is 19E in hexadecimal.The response from the slave to the master will be:11.5.2 Reading a Parameter ValueRead the value in par. 3-41Ramp 1 Ramp Up TimePKE = 1155 Hex - Read parameter value in par. 3-41Ramp 1 Ramp UpTimeIND = 0000 HexPWEHIGH = 0000 HexPWELOW = 0000 HexIf the value in par. 3-41Ramp 1 Ramp Up Time is 10 s, the response fromthe slave to the master will be:NB!3E8 Hex corresponds to 1000 decimal. The conversion index for par. 3-41Ramp 1 Ramp Up Time is -2, i.e. 0.01.par. 3-41Ramp 1 Ramp up Time is of the typeUnsigned 32.11 RS-485 Installation and Set-up FC 300 Design Guide238 MG.33.BC.02 - VLT® is a registered Danfoss trademark11
