All other mounting holes are electrically isolated. Please note that not all holes have to be used for mounting
the pcb. At least the mounting holes in all four corners and two in the middle (6 altogether) should be used to
ensure adequate support of the pcb when inserting / removing connectors in order to avoid significant bending
of the pcb.
In any case: please remove / attach mating connectors carefully – supporting the pcb if necessary!

5.1.3 USB connector
The TMCM-3312 / TMCM-3313 offers a Micro USB connector (Type B, device interface) for communication. The USB
interface supports USB high speed communication (12Mbit/s). With USB attached the digital logic part of the
TMCM-3312 / TMCM-3313 will be supplied via USB (USB powered mode) if there is no main supply available. This
mode may be used for firmware-updates, TMCL-program download or parameter settings etc. (requires USB
connection, only). Please note that in USB stand-alone mode (main board supply available) the board might still
draw current from the USB supply – depending on the voltage level of the USB +5V and the on-board generated
+5V.
5.1.4 Inputs
The TMCM-3312 / TMCM-3313 offer four analog inputs (nom. 0..10V range) which may be used as digital inputs,
also (+24V tolerant).
The four inputs are available via one 10 pin Molex MicroFit™ connector (Molex part no. 430451012). Mating
connector housing e.g. Molex 43025-1000, contacts Molex 43030-0007. Please note that there are alternative options
available from Molex for both, mating housing and contacts.

5.2.1 EtherCAT™ connector
There are two EtherCAT™ connectors on the board – one for LINK IN (towards / coming from EtherCAT™ master)
and one for LINK OUT (for connecting further slaves) connection.
A standard RJ45 plug connector (as used for 10/100Mbit/s Ethernet) is used for EtherCAT™ communication.
Standard CAT cables suitable for 100Mbit/s Ethernet (e.g. CAT 5 / 5e etc.) might be used for connection. The PHYs
used on the TMCM-3313 support auto MDI-X – therefore, TX and RX signals on the connector might be exchanged
– e.g. cables with straight-through pin-assignment can be used.

interface supports USB high speed communication (12Mbit/s). With USB attached the digital logic part of the
TMCM-3312 / TMCM-3313 will be supplied via USB (USB powered mode) if there is no main supply available. This
mode may be used for firmware-updates, TMCL-program download or parameter settings etc. (requires USB
connection, only). Please note that in USB stand-alone mode (main board supply available) the board might still
draw current from the USB supply – depending on the voltage level of the USB +5V and the on-board generated
+5V.
5.2.3 Inputs
The TMCM-3312 / TMCM-3313 offer four analog inputs (nom. 0..10V range) which may be used as digital inputs,
also (+24V tolerant).
The four inputs are available via one 10 pin Molex MicroFit™ connector (Molex part no. 430451012). Mating
connector housing e.g. Molex 43025-1000, contacts Molex 43030-0007. Please note that there are alternative options
available from Molex for both, mating housing and contacts.

5.5 Power supply
For proper operation care has to be taken with regard to power supply concept and design. The TMCM-3312 /
TMCM-3313 includes about 4000µF/63V of supply filter capacitors. In addition, the module includes a 48V
suppressor diode for over-voltage protection. Nevertheless, it is important to make sure that supply voltage will
not rise beyond the upper limit of +53V! Please note: during motor deceleration the driver stage might feedback
energy from the motor into the supply rail and supply voltage might increase. In order to limit the supply voltage
a brake chopper circuit has been included on the board. When activated in software and together with an external
power resistor this circuit will limit the supply voltage.
CAUTION
Always keep the power supply voltage (+48V) below the upper limit of 53V!
Otherwise the on-board electronics might be seriously damaged. Especially, when the selected operating
voltage is near the upper limit a regulated power supply is highly recommended. In addition, the on-board
brake chopper may be used together with an external power resistor connected to the Resistor connector in
order to limit supply voltage.
Always keep the digital logic power supply voltage (+48V_LOGIC) below the upper limit of 53V!
Otherwise the on-board electronics might be seriously damaged. Especially, when the selected operating
voltage is near the upper limit a regulated power supply is highly recommended.
Always keep the logic power supply voltage (+48V_LOGIC) above or equal to the main power supply (on
the Power supply connector)!
Otherwise the on-board electronics (diode connection between +48V main power supply input and +48V logic
supply input) might be seriously damaged.
There is limited reverse polarity protection, only!
The module will short any reversed supply voltage.
5.6 RS485
For remote control and communication with a host system the TMCM-3312 provides a two wire RS485 bus
interface. For proper operation the following items should be taken into account when setting up an RS485
network:
1.
BUS STRUCTURE:
The network topology should follow a bus structure as closely as possible. That is, the connection
between each node and the bus itself should be as short as possible. Basically, it should be short
compared to the length of the bus. The TMCM-3312 offers two connectors which are connected directly
to each other and the on-board RS485 transceiver. Using both connectors for passing through the bus
will help with keeping a proper bus topology.

2.
BUS TERMINATION:
Especially for longer busses and/or multiple nodes connected to the bus and/or high communication
speeds, the bus should be properly terminated at both ends. The TMCM-3312 does not integrate any
termination resistor. Therefore, 120 Ohm termination resistors at both ends of the bus have to be added
externally.
3.
NUMBER OF NODES:
The RS485 electrical interface standard (EIA-485) allows up to 32 nodes to be connected to a single bus.
The bus transceivers used on the TMCM-3312 units (SN65HVD1781D) have a significantly reduced bus load
and allow a maximum of 255 units to be connected to a single RS485 bus using TMCL firmware. Please
note: usually it cannot be expected to get reliable communication with the maximum number of nodes
connected to one bus and maximum supported communication speed at the same time. Instead, a
compromise has to be found between bus cable length, communication speed and number of nodes.
4.
COMMUNICATION SPEED:
The maximum RS485 communication speed supported by the TMCM-3312 hardware is 1Mbit/s. Factory
default is 9600 bit/s. Please see separate firmware manuals for information regarding other possible
communication speeds below the upper limit in hardware.
5.
NO FLOATING BUS LINES:
Avoid floating bus lines while neither the host/master nor one of the slaves along the bus line is
transmitting data (all bus nodes switched to receive mode). Floating bus lines may lead to communication
errors. In order to ensure valid signals on the bus it is recommended to use a resistor network connecting
both bus lines to well defined logic levels.
There are actually two options which can be recommended:

5.7 CAN
For remote control and communication with a host system the TMCM-3312 provides a CAN bus interface. For
proper operation the following items should be taken into account when setting up a CAN network:
1.
BUS STRUCTURE:
The network topology should follow a bus structure as closely as possible. That is, the connection
between each node and the bus itself should be as short as possible. Basically, it should be short
compared to the length of the bus. The TMCM-3312 offers two connectors (RJ45) which are connected
directly to each other and the on-board CAN transceiver. Using both connectors for passing through the

5.7.1 CAN adapter
As part of the cable loom for the TMCM-3312 (G4-CABLE) an adapter pcb is vailable (RJ45-2-DSUB_G4_V10) for
making CAN bus connection via standard D-SUB connectors instead of the RJ45 available on the TMCM-3312. A
standard e.g. CAT5 ethernet cable might be used to connect the RJ45 connector on the TMCM-3312 with the RJ45
connector on the adapter pcb. The D-SUB connector on the adapter pcb might then be used to connect further
slaves or the master with CAN D-SUB connectors. Please make sure to maintain a proper bus structure while
using the adapter pcb.
