Also refer to the documentation: "Universal SerialInterface Protocol Specification“:Order No. E20125-D0001-S302-A1 (German)Order No. E20125-D0001-S302-A1-7600 (English)2. If the PROFIBUS Module is connected to the SUB-Dsocket on the front panel, then the internal RS 485connections of the 6SE32 drive (terminals 23 and 24) maynot be used.3. If the Clear Text Display is connected to the SUB-Dsocket on the front panel, then the internal RS485connections on the 6SE32 drive (terminals 23 and 24)must not be connected to a PC, PLC or any other serialbus master.4. It is not possible to connect simultaneously thePROFIBUS Module and the Clear Text Display to thedrive.5.4 Control Terminal StripsAll of the functions required to operate and monitorMICROMASTER and MIDIMASTER are accessible via controlterminal strips.• Control commands, e.g. on/off, clockwise/counterclockwise,inching.• Analog setpoint inputs.• Digital set-point inputs, e.g. fixed frequency.5.5 Clear Text Display(Optional)5.5.1 Use of the Clear Text DisplayThe optional Clear Text Display is intended to enhance theease of use of the MICROMASTER, MICROMASTER Vectorand MIDIMASTER Vector. It is also intended for use with theCOMBIMASTER. The user is offered a text-driven format forcommissioning, parameterising, configuring and operating theinverter. The following features are included:• Illuminated high resolution LCD screen with adjustablecontrast.• 7 languages.• Central device for up to 31 inverters which are networkedtogether via USS.• Up to 10 parameter sets can be stored in non-volatilememory for uploading and downloading between the cleartext operator panel and the drive.• Help texts for diagnosing faults.• Isolated RS232 interface for connecting to a PC.The Clear Text Panel is a push fit to the front of the drive (noscrews necessary) and is removed by pulling the clipunderneath the unit.The unit may be connected to the drive via a cable and usedas a hand-held terminal. The unit can also be fitted to acabinet door and thus used as a low cost man machineinterface for one or more drives in a cabinet.• Digital outputs, e.g. operation, alarm.• Analog outputs eg. frequency setpoint, output current.The response times of the inputs are as follows:Digital input:25 ms, depending on thedebounce time (P056)Analog input: 15 ms for step signals (> 0.5 V)RS 485 interface:25 msFor further information on using the control terminals, seesection 3.4.5/2 Siemens DA 64 – 1998/99 (04/99)
