Terminals at the front of the ontroller b oard 6.13T
6.13.6 Inremental eno der emulation (optional extender b oard)
The incremental encoder emulation is based on a PCB option, which allocates the only extension slot of the
b maXX® BM3400 device.
The front-sided sub-D-connector (X27), which is assembled at a device with an integrated incremental en-
coder emulation to the right of the RS232-connector (X23), has the following pin assignment:

Pin no. Assignment
1 GND encoder supply
2 +5V encoder supply
3 RS422 track + ZERO
4 RS422 track - ZERO
5 RS422 track + B
6 Not assigned
7 RS422 track - A
8 RS422 track + A
9 RS422 track - B
6.13.6.1 Conneting able for inremental eno der emulation
The connecting cables you must produce yourself.
1. Use the following materials:
• Cable: LiYCY 5 x (2 x 0.14) + 2 x 0.5 mm Cu-braid.
• Sub-D socket 9 contacts, (connection incremental encoder emulation)
• Plug-in connector or other conncection accordant to encoder input of the target device
2. Connect
• the cable shield plane with the housing of the sub-D-socket
• the socket (9 contacts) with the cable according to the specifiations in paragraph «Incremental
encoder emulation (optional extender board)» on page 103. Thereby consider, that the twisted in
pairs lines are used for track signals belonging together(+ZERO and -ZERO, +A and -A as well as
+B and -B).
3. Connect the other end of the ca ble with the suitable c onnection or plug-in connector, which fits to the
target device. If b maXX® BM3400 shall be the target device, the assignment is found under «Square
wave incremental encoder (X24, X25, coding E)» from page 95.
For the signals „+5V sense line“ and „GND sense line“ within the 9 contacts of the sub-D-plug there are
no free pins. In order to adjust the voltage dr op via long encoder connecting cables, „+5V sense line“
must be connected to pin 2 and „GND sense line“ to pin 1 of the 9-pole sub-D-socket.
