    Unit Profile Scaling of process data Unit Profile Scaling of process data The process data are always transmitted in hexadecimal form to make for simple calcu- lation in the ongoing system process. Parameters with identical units of measurement receive the same scaling so that the higher-level automation device can directly com- pare the set and actual values in the application program.

  • Page 33: Definition Of The Control Word

    Unit Profile Definition of the control word Definition of the control word The control word is 16 bits wide. Each bit has been assigned an inverter function. The low byte consists of eight fixed function bites that are always valid. The assignment of the more significant eight control bits varies for the different control words.
  • Page 34 Unit Profile Connection of control commands As soon as one of the three processing blocks triggers a control command of higher pri- ority (such as RAPID STOP or CONTRL.INHIBIT), it will become effective. The binary inputs will generally remain active even if the inverter is controlled via the pro- cess data (P101 control source = RS-485 / SBus).

  • Page 41 Unit Profile Status word definition Fault/warning The inverter reports a possible fault or warning in bit 5 of the status word. A fault gener- ally causes the inverter to cease operation, while a warning may only be temporary with- out influencing the inverter behavior. That is why you should also evaluate status bit 1: Ready for operation to determine the exact reason for a fault.
  • Page 42 Unit Profile Status word definition Status word 1 Status word 1 contains the status information in the basic status block and the unit sta- tus or the error number in the more significant status byte. Depending on the fault bit, the unit status is displayed in case of fault bit = 0 or in case of problems (fault bit = 1), the error number.
