Notes:

1. Refer to the following documentation: "Universal Serial

Interface Protocol Specifications":

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-D

connector at the equipment cover, then the internal

RS485 ports of the 6SE32 drive (terminals 23 and 24) do

not have to be used.

3. If the plain text operator panel is connected at the SUB-D

connector at the equipment cover, then it is not

permissible to connect the internal RS485 ports of the

6SE32 drive (terminals 23 and 24) to a PC, a PLC or any

other serial bus master.

4. It is not possible to simultaneously connect the PROFIBUS

module and the plain text operator panel to the drive

inverter.

4.4 Control terminal strips

All of the functions required to control and monitor the

MICROMASTER and the MIDIMASTER are accessible via

control terminal strips.

· Control commands, e.g. on/off, clockwise/counter-

clockwise, jogging

· Analog setpoint inputs

· Digital setpoint inputs, e.g. fixed frequency

· Digital outputs, e.g. operation, alarm

· Analog outputs, e.g. frequency setpoint, output current

The response times of the inputs are as follows:

Digital input: 25 ms, depending on the de-

bounce time (P056)

Analog input: 15 ms for stepping signals (> 0.5

RS485 interface: 25 ms

Refer to Section 3.4 for additional information on using the

control terminals.

4.5 Plain text operator panel (optional)

4.5.1 Using the plain text operator panel

The optional plain text operator panel is intended to

additionally enhance the user friendliness of the

MICROMASTER, MICROMASTER Vector and

MIDIMASTER Vector. Furthermore, it has been designed for

use with COMBIMASTER. This provides the operator with a

plain text basis for commissioning, parameterizing,

configuring and operating the drive inverter. The following

functions are provided:

· Back lit LCD display with a high resolution and contrast

control.

· 7 languages

· Up to 31 drive inverters can be centrally controlled, which

are networked via USS.

· Up to 10 parameter sets can be saved in the non-volatile

memory for uploading and downloading data between the

plain text operator panel and drive.

· Help texts for diagnostics (troubleshooting).

· Insulated RS232 interface to connect to a PC.

The plain text operator panel fits perfectly into the front panel

of the drive (screws are not required) and can be easily

removed by lifting a bracket below the unit.

The plain text operator panel can be connected to the drive

using a cable which means that it can be used as mobile

terminal. It can also be mounted on a cabinet door thus

serving as a favorably priced "Man/machine" interface for

one or several drives in a cabinet.

Caution:

When using the plain text operator panel as interface

converter RS232/ RS485 or without drive inverter,

then an additional 6V DC power supply is always required.

The specifications are listed on Page 4/4.
