Serial Interfaces
7.1
Panel-Port
The Panel Port is normally used for connection of the
control panel. The default settings of this interface are
as follows:
Signal level:
+12V / 0V
Data format:
UART
Message format:
Modbus-Protocoll
Transmission method:
half-duplex
Baudrate:
9.600 Baud
Number of Data bits:
8
Number of Stop bits:
2
Parity-Bit:
none
Alternatively, this interface may be used for purpose
of external drive control, e.g. for connection to RS232-
COM-Ports of PC's or to RS485 busses. A specific
adapter ("RS232/RS485-Adapter") is available as an
option which converts the internal interface signals
according to the require-
ments of the selected RS
232 or RS 485 interface.
This adapter is plugged into
the drive, instead of the con-
trol panel, and is ready for
operation.
Either the con-
trol panel or the special
adapter can be used, not
both together.
The adapter provides screw
connectors for the RS 485-
Bus and a 9-pole SUB-D
connector for the RS232.
Either the RS 485 or RS232
can be used, not both to-
gether.

Settings of Panel-Port
Status word allocation
4 bits of the status word (data set 2.1) can be param-
eterized. The signals are selected in the parameters
MSW bit 11 Ass (6.22), MSW bit 12 Ass (6.23), MSW
bit 13 Ass (6.24) and MSW bit 14 Ass (6.25).
Data set allocation
The data sets 2.2 and 2.3 transmit two actual values.
The actual values are selected in the parameters data
set 2.2 Ass (6.20) and data set 2.3 Ass (6.21).
Default value for
data set 2.2 is Speed Act
data set 2.3 is Arm Cur Act
For special purposes data set 3 can transmit directly
five digital values and two analogue values which are
fix assigned to the outputs.
Assignment:
Data set 3.1 bit 0 = DO1
digital value
Data set 3.1 bit 1 = DO2
digital value
Data set 3.1 bit 2 = DO3
digital value
Data set 3.1 bit 3 = DO4
digital value
Data set 3.1 bit 4 = DO5
digital value
Data set 3.2
= AO1/2 analogue value
Data set 3.3
= AO1/2 analogue value
In the following sections, the three available serial
interfaces are described in detail.
Switch Off and On electronics supply to initialize the Panel-Port for drive control
via PLC.
If these parameter settings done via panel after electronics supply On, panel
display will show 'Comm Loss' due to the panel communication is disabled now.
For resetting parameters PC Tool Drive Window Light is needed!
