Part number:

If your PC/PG only has USB interfaces instead of the RS232 interface, you can use standard USB<->RS232 converters. Please make sure that you use up-to-date drivers from the respective manufacturers, particularly also for 64-Bit-Systems.

Note
The UC232A converters from Aten were tested.
If data transfer rate problems occur, then the min. baud rate should be set to 38400.


Settings
Drive Monitor Interface COM1 - COM4 A COM port number can be selected between 1-4 (dependent on the PC setting).
Baud rate 9600 or higher A higher baud rate might give the better access; e.g. 38400 Baud
Bus operation RS485 Automatic mode Online operation is not possible without this setting
 
STARTER Access point DEVICE(STARTER, SCOUT) --> PC COM-Port (USS)  
Interface Parameter Assignment Used PC COM-Port (USS)  
Interface COM1 - COM7 A COM port number can be selected between 1-7 (dependent on the PC setting).
Baud rate 9600 or higher A higher baud rate might give the better access; e.g. 38400 Baud

MICROMASTER 4 (MM4): What different connection arrangements are possible with the optional Operator Panel and communication Options for the MM4 inverter?Go to beginning
Part number:

The MM4 has two separate serial interface ports, which operate independently. An RS485 port is available through terminals 14 and 15 (MM420) or terminals 29 and 30 (MM430 and MM440), and an RS232 port is available on the interface connector. This allows various options and arrangements to be connected:


1. Fitting an AOP or BOP directly to the MM420:

In this case the AOP or BOP use the RS232 interface built into the interface connector. This allows the RS485 interface, at terminals 14 and 15 (MM420) or terminals 29 and 30 (MM430 and MM440), to be used for other communications if required.


2. Using the BOP/AOP single mounting kit (6SE6400-0PM00-0AA0):
 


 

This kit simply extends the existing RS232 interface, bringing connections and power from the interface connector to terminals, which can then be wired to the AOP or BOP mounted in the door. Tests indicate that, although RS232 should be limited to 5m of cable, up to 20m of cable can operate satisfactorily, but this is not guaranteed. Again, the RS485 interface is available for other uses.


3. Using the AOP mounting kit (6SE6400-0MD00-0AA0):
 


 

In this installation, the AOP connects to the RS485 interface on the MM4 and also takes 24V power from the unit. If further inverters are connected, they can be “daisy chained” using the RS485 terminals on each inverter. The AOP can then communicate with all inverters using the RS485. RS485 connections can operate over long distance, typically several hundred meters, but the connection from the AOP to the inverter includes the supply, so this should be limited to 10m.
An isolated RS232 interface is also provided on the kit, which allows communication between the AOP and a computer for example. In this case, the PC communicates with the AOP, which then communicates with the drives.
The DIP switch on the unit allows the use of a BOP in the unit in place of the AOP when only one drive is used. To enable this function, close switch one. Note this function has not been tested. Switch 2 has no function, and should not be used.
An additional AOP or BOP can be optionally fitted to any inverter as this uses the RS232 interface.


4. PC to MM4 Connection Kit (6SE6400-1PC00-0AA0):

This kit enables a PC to communicate using the RS232 interface via a simple adaptor and RS232 cable. The adaptor incorporates optical isolation. The RS485 terminals are available for other uses.


5. Communications Options – PROFIBUS (6SE6400-1PB00-0AA0):

When the PROFIBUS module is fitted to the inverter, the RS485 interface is not available. The RS232 interface may be used for BOP, AOP connections etc.

MICROMASTER 430: Is it possible to use the AOP with a MM430?Go to beginning
Part number:

For operation with the MM430, the AOP has neither been system-tested nor released1!
BOP-2 (6SE6400-0BE00-0AA0) is exclusively released for operation with the MM430.

Although it is possible to download data from an MM430 using an AOP - dependent on the firmware and software release - however, the data would not be complete.

The BOP-2 (6SE6400-0BE00-0AA0) and the STARTER software are available for operator control and parameterization.

We recommend that a PC is used to save and transfer parameter sets.

To do this, the appropriate software must be installed (STARTER) and a PC-drive inverter connecting kit (6SE6400-1PC00-0AA0)2.

Notes:

1       This is also valid for all other operator panels. You can find information on this in Catalog
         DA 51.2 / Page 0/8.

2      As an alternative, to establish a connection to the PC, an RS485 – RS232 converter can also be
        use (e.g. the PC drive inverter connecting kit of the MM410, 6SE6400-0PL00-0AA0, the
        RS485 connecting cable are not included in the scope of supply of the converter.
