Master DrivesCBD05/20/995 Start-up5.2 Process data combination5.2.1 Setpoint channel (master to drive)♦ The first word (associated combination value: 3001) of the received process data is always assigned to controlword 1 (STW1). The significance of the control word bit is provided in the converter Instruction Manual, Section 4.3“Start-up aids”.♦ The second word is always assigned to the main setpoint (HSW).If the main setpoint is transferred as 32-bit process data, then it also occupies word 3. In this case, the mostsignificant part is transferred in word 2 and the least significant part of the main setpoint, in word 3.♦ If a control word 2 (STW2) is transferred, then STW2 is always assigned the fourth word (associated combinationvalue = 3004). The significance of the control word bit can be taken from the converter Instruction Manual, Section“Start-up aids”.♦ The combination value is always 4 digits. For the combination values, associated with the process data (PZD1 toPZD16), please refer to Fig. 4.4.Data entry at the PMU is realized as a 4-digit number (e. g. 3001). For parameterization via DeviceNet bus, thecombination value is entered via the bus, as well as via the PMU (e. g. combination value 3001 is transferred as3001 hex; refer to the following example in Fig. 5.8).Example for the setpoint channel:PZD combination for control word 1 bits (STW1),main setpoint (HSW) and control word 2 bits (STW2).At the converter via PMUP554.1 = 3001SignificanceControl word 1 bit 0 (Source ON/OFF1) via dual port RAM interface (word 1)P555.1 = 3001Control word 1 bit 1 (Source ON/OFF2) via dual port RAM interface (word 1)P443.1 = 300216 bit main setpoint (Source main setpoint) via dual port RAM interface (word 2)P588.1 = 3004Control word 2, bit 28 (Source of message “external warning 1”) via dual port RAMinterface (word 4)42 Siemens AG 477 759 4070 76 J AA-74SIMOVERTMASTERDRIVES Betriebsanleitung/OperatingInstructions
