SAC-RL100-M11T Semiconductor encoder

The thyristor diagnosis procedure is successfully finished if the panel displays the message None. That means no defective thyristor(s) were detected. • Main contactor is switched Off. If the diagnosis procedure failed the fault message Hardware Fault (F02) is displayed. Detailed information for the failure reason can be read from parameter Diagnosis (7.03). More explanations to the diagnosis messages are available in the chapter Troubleshooting. Pressing the LOC button on the panel again the control is switched back to the input/output terminals. The LOC message in the panel status row disappears.4.5.10 Internal Scaling You can display all parameters of the DCS400 in their physical quantities by means of operating panel or the PC tool, in the way they are specified in the column "Unit" at the parameter list: A, V, rpm, Hz, %, s, ms, text, integer, mH, mOhm, %/ msec, °C, kW, hex. In case of serial drive control (reference/actual value transmission) with PLC (field bus coupling, RS232 port, panel port) the internal scaling of these values shall be considered. There is no transmission of physical quantities but values are transmitted in binary representation.

Example

 The maximum speed reference of a drive of 3000 rpm is transmitted in a 16-bit telegram word. In this case 3000 rpm are equal to the maximum value of 20.000 decimal i.e. the resolution of the speed is in steps of 1/20,000. This value 20,000 is transmitted on the bus as a binary value in a 16-bit combination of "0" and "1". Each bit has a decimal valency. Hence 20,000 shall be distributed over these 16 bits in such a way that the decimal sum of set "1's" is again 20,000.

This internal scaling does not apply to the transmission of parameters via PLC. In this kind of transmission, decimal values are simply transmitted in binary form i.e. the values of the parameter list are represented in decimal form and without a decimal point in a 16- bit word. Decimal values without decimal point are transmitted in the same form as they are represented in the parameter list. In this case, e.g. the parameter Base Speed (1.05) will be set to 3000 if the nominal speed is intended to be 3000 rpm. Decimal values with decimal point are simply transmitted as a number without decimal point but with all decimal digits. In this case, e.g. the parameter Field Cur Nom (1.03) will be set to 650 if the nominal field current is intended to be 6.50 A. Parameters with other engineering units shall be treated in the same way.
