FC 300 Design GuideHow to Program" Present Output FrequencyThe value of the adjustable frequency driveíspresent output frequency is transferred as a16-bit word. The value is transferred as wholenumbers 0 - ±32767 (±200%).16384 (4000 Hex) corresponds to 100%.Output frequency has this format:0-16384 (4000 Hex) 0-100% (Par. 4-12 MotorSpeed Low Limit - par. 4-14 Motor Speed High Limit).Example - Status word and current output frequency:The adjustable frequency drive informs themaster that the current output frequency is50% of the output frequency range.Par. 4-12Motor speed low limit = 0 HzPar. 4-14Motor speed high limit = 50 HzStatus word = 0F03 Hex.Output frequency= 2000 Hex => 50% of thefrequency range, corresponding to 25 Hz." Example 1: For Controlling the Driveand Reading ParametersThis telegram reads par. 16-14 Motor Current.Telegram to the adjustable frequency drive:stx lge adr pke ind pwe, high pwe, low pcd 1 pcd 2 bcc02 0E 01 6 4E 00 00 00 00 00 00 00 00 00 00 45All numbers are in hex format.The response from the adjustable frequency drive corresponds to the command above but pwe,highand pwe,low contain the actual value of par. 16-14 multiplied by 100. If the actual output currentis 5.24 A, the value from the adjustable frequency drive is 524.* default setting ( ) display text [ ] value for use in communication via serial communication port288 MG.33.B6.22 - VLT is a registered Danfoss trademark
