This is also the interface to allow the optionalPROFIBUS Module or Clear Text Operator Panel to beconnected. The drive can be connected directly to a PC byusing the RS232 interface on the Clear Text Operator Panel.5.3 Serial RS 485 InterfaceThe RS 485 interface of the MICROMASTER andMIDIMASTER operates with the USS protocol, can benetworked with 31 nodes through a bus and permits amaximum data transmission rate of 19.2 kbit/s.The RS 485 interface is accessible via a SUB-D socketconnector (see Table 1 for Pin Assignment) and, on the6SE32 drives, control terminal strip.• Frequency inverter start-up.• Operator control.54321• Motor On/off, increase/decrease motor frequencysetpoint.9876• Selection of clockwise/counter-clockwise direction ofrotation, inching frequency via the jog key.• Starting and stopping with a preset frequency.• Displaying motor frequency setpoints and actual values.• Displaying and changing parameters.• Displaying frequency inverter status.• Displaying alarm messages.• Displaying and resetting fault messages.The function keys can be individually inhibited.
