3 Order codes
The TMCM-6210 unit is available with two different firmware options:
Table 3.1: TMCM-6210 order code
The TMCM-6211 unit is available as:
Table 3.2: TMCM-6211 order code
A cable loom is available, also:
Please note: there is one cable loom available for a complete family of modules in order to speed-up initial setup
of these modules. The family consists of these currently planned / available modules: TMCM-6210/6211, TMCM6212/6213, TMCM-3212/3213, TMCM-3214/3215, TMCM-3312/3313 and TMCM-3314/3315. Not all cables are required
for all modules – some cable will fit or will be helpful for some modules, only. Module numbers in parenthesis
behind each cable in the table above indicate whether the particular part of the cable loom can be used with
the TMCM-6210 and / or TMCM-6211.
The dimensions of the TMCM-6210 and TMCM-6211 controller/driver board are approx. 215mm x 100mm x 21mm.
Maximum component height (height above PCB level) without mating connectors is around 17mm above PCB
level and 2mm below PCB level. There are 12 mounting holes for M3 screws (3.2mm diameter) altogether for
mounting the PCB.
Figure 4.1 Dimension of TMCM-6210 / TMCM-6211 and position of mounting holes
Please note: TMCM-6210 and TMCM-6211 share the same PCB with different assembly options regarding the
interface section. Dimensions, mounting holes and board mounting considerations (see chapter below) are the
same for both boards.
The TMCM-6210 / TMCM-6211 offer 12 metal plated mounting holes. One hole (lower right) is connected to onboard system ground (connected to power supply input ground) via 1M (500VDC) || 1nF (1kV). The same
combination or resistor and capacitor is used for connecting the RJ45 shield ground (connector enclosure) to
power supply input ground (see figure 4.1).
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!
The TMCM-6210 and TMCM-6211 are two members of a new family of modules with a modular architecture
composed of so called “bricks”.
The TMCM-6210 and TMCM-6211 consist of one interface brick, three dual-axes stepper motor controller / driver
bricks and one supply brick. With the TMCM-6210 the interface brick offers CAN and RS485 interfaces while with
the TMCM-6211 the EtherCAT™ option is assembled instead. All other bricks are the same for both modules.
Figure 5.1 different bricks used for the TMCM-6210 / TMCM-6211
5.1 TMCM-6210 Interface Brick
The interface brick of the TMCM-6210 offers RS485, CAN and USB interfaces for communication, four general
purpose analog inputs (which can be used as digital inputs as well) and four open-drain outputs.
Table 5.1 TMCM-6210 interface brick: connectors and mating connectors
5.1.1 RS485 connector
There are two RS485 connectors on the board with the same pin assignment – pins directly connected to each
other. The second connector may be used for attaching a bus termination resistor to the RS485 bus (there is no
termination resistor on-board) or for further distribution of the RS485 bus signals to other RS485 communication
nodes while maintaining a proper bus structure.
A three pin Molex MicroFit™ connector (Molex part no. 436500315) is used for RS485 connection. Mating connector
housing e.g. Molex 43645-0300, contacts Molex 43030-0007. Please note that there are alternative options available
from Molex for both, housing and contacts.
Table 5.1: Interface Brick: RS485 connector
5.1.2 CAN connector
There are two CAN connectors on the board with the same pin assignment – pins directly connected to each
other. The second one may be used for attaching a bus termination resistor to the RS485 bus (there is no
termination resistor on-board) or for further distribution of the CAN bus signals to other CAN nodes while
maintaining a proper bus structure.
A standard RJ45 plug connector is used for CAN communication. Standard CAT cables (e.g. CAT 5, non-crossing)
might be used for connection. Pin assignment of the RJ45 is based on the CiA 303-1 recommendation.

5.2 TMCM-6211 Interface Brick
The interface brick of the TMCM-6210 offers EtherCAT™ and USB interfaces for communication, four general
purpose analog inputs (which can be used as digital inputs as well) and four open-drain outputs.
Table 5.5: TMCM-6211 interface brick: connectors and mating connectors
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-6211 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.

not rise beyond the upper limit of +27V! 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.
5.6 RS485
For remote control and communication with a host system the TMCM-6210 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-6210 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.
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-6210 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-6110 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-6210 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:
Add resistor (Bias) network on one side of the bus, only (120R termination resistor still at both ends):
Figure 4.4: Bus lines with resistor (Bias) network on one side, only
Or add resistor (Bias) network at bothends of the bus (like Profibus™ termination):
Figure 4.5: Bus lines with resistor (Bias) network at both ends
Certain RS485 interface converters available for PCs already include these additional resistors (e.g. USB-2485 with bias network at one end of the bus).
5.7 CAN
For remote control and communication with a host system the TMCM-6210 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-6210 offers two connectors (RJ45) which are connected
directly to each other and the on-board CAN transceiver. Using both connectors for passing through the
bus will help with keeping a proper bus topology.
Figure 5.6: CAN bus structure
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-6210 does not integrate any
termination resistor. Therefore, 120 Ohm termination resistors at both ends of the bus have to be added
externally.
As part of the cable loom for the TMCM-6210 (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-6210. A
standard e.g. CAT5 ethernet cable might be used to connect the RJ45 connector on the TMCM-6210 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.
The TMCM-6210 and TMCM-6211 offer 4 open-drain (N-channel MOSFET) general purpose outputs available at the
output connector of the interface brick part. The internal connection of the N-channel MOSFETs together with a
flyback / freewheeling diode can be seen in figure 5.8. When activating the MOSFET the related output will be
pulled low (sometimes called npn-style switch). Please note the internal fuse limiting the current that can be
drawn from the output connector.
Figure 5.8: General purpose output – internal circuit (simplified)
In TMCL axis parameter 6 (motor run current) and 7 (motor standby current) can be used
for motor current setting:
SAP 6, 0, <value> // set run current
SAP 7, 0, <value> // set standby current
For <value> numbers between 0 (minimum) and 255 (maximum) are supported. Motor
current is scaled linearly up-to 0.7A RMS / 1A peak.
(read-out value with GAP instead of SAP. Please see separate TMCM-6210 / TMCM-6211

The TMCM-6210 is a highly integrated controller/driver module for 6 stepper motor axes which can be controlled
via several serial interfaces (CAN, RS485 and USB – depending on firmware). Communication traffic is kept low
since all time critical operations (e.g. ramp calculations) are performed on board. The nominal supply voltage of
the unit is 12V or 24V DC. The module is designed for both, standalone operation and direct mode. Full remote
control of device with feedback is possible. The firmware of the module can be updated via one of the serial
interfaces (depending on module and firmware type).
In Figure 10.1 the main parts of the TMCM-6210 are shown:
- Microcontroller, responsible for overall control – executes the firmware (either TMCL or CANopen incl. the
communication stack)
- 3 dual-axes motion controller and driver with calculation of ramps (linear and sixPoint™) and speed
profiles internally in hardware
- interface for an external (e.g. optical) incremental A/B/N encoder (differential RS422 signals) for each axis
- interface for HOME / REFL / REFR reference switches for each axis (either encoder interface or reference
switches can be selected in software)
- 4 general purpose analog / digital inputs
- 4 general purpose digital (open-drain) outputs
- Three serial communication interfaces: CAN, RS485 and USB (Micro-USB-connector). While CAN and RS485
are intended for in-system control and operation (for CANopen firmware just CAN) the USB interface may
be primarily used for parameter settings and firmware updates.
The TMCM-6211 is a highly integrated controller/driver module for 6 stepper motor axes which offers an EtherCAT™
interface in addition to USB for communication. The nominal supply voltage of the unit is 12V or 24V DC. Full
remote control of the device with feedback is possible using the CANopen over EtherCAT™ (CoE) firmware. The
firmware of the module can be updated via one of the serial interfaces.
In Figure 10.1 the main parts of the TMCM-6211 are shown:
- Microcontroller, responsible for overall control – executes the firmware (CANopen over EtherCAT, CoE)
- 3 dual-axes motion controller and driver with calculation of ramps (linear and sixPoint™) and speed
profiles internally in hardware
- interface for an external (e.g. optical) incremental A/B/N encoder (differential RS422 signals) for each axis
- interface for HOME / REFL / REFR reference switches for each axis (either encoder interface or reference
switches can be selected in software)
- 4 general purpose analog / digital inputs
- 4 general purpose digital (open-drain) outputs
- EtherCAT™ and USB interfaces for communication. The EtherCAT™ interface is intended for in-system
control and operation (using CoE firmware), while USB may be used for parameter setting and firmware
updates
