TRINAMICS UNIQUE FEATURES – EASY TO USE WITH TMCL
stallGuard2™
stallGuard2 is a high-precision sensorless load measurement using the back EMF on the
coils. It can be used for stall detection as well as other uses at loads below those which
stall the motor. The stallGuard2 measurement value changes linearly over a wide range
of load, velocity, and current settings. At maximum motor load, the value goes to zero or
near to zero. This is the most energy-efficient point of operation for the motor.

coolStep™
coolStep is a load-adaptive automatic current scaling based on the load measurement via
stallGuard2 adapting the required current to the load. Energy consumption can be
reduced by as much as 75%. coolStep allows substantial energy savings, especially for
motors which see varying loads or operate at a high duty cycle. Because a stepper motor
application needs to work with a torque reserve of 30% to 50%, even a constant-load
application allows significant energy savings because coolStep automatically enables
torque reserve when required. Reducing power consumption keeps the system cooler,
increases motor life, and allows reducing cost.

Table 4.1 Connector for power supply and interfaces
4.3.1.1 Power Supply
For proper operation care has to be taken with regard to power supply concept and design. Due to space
restrictions the TMCM-1140 includes about 40µF/35V of supply filter capacitors. These are ceramic
capacitors which have been selected for high reliability and long life time. The module includes a 28V
suppressor diode for over-voltage protection. There is no reverse polarity protection. The module will
short any reversed supply voltage due to the suppressor diode (uni-directional version) and the internal
diodes of the driver transistors.
It is important that the power supply voltage is kept below the upper limit of 28V (please see also
chapter 6, operating values). Otherwise the driver electronics might be seriously damaged! Especially,
when the selected operating voltage is near the upper limit a regulated power supply is highly
recommended.
It is recommended to connect an electrolytic capacitor of significant size (e.g. 470µF/35V) to the power
supply lines next to the PD42-1140!
In addition to power stabilization (buffer) and filtering this added capacitor will also reduce any voltage
spikes which might otherwise occur from a combination of high inductance power supply wires and the
ceramic capacitors. In addition it will limit slew-rate of power supply voltage at the module. The low ESR
of ceramic-only filter capacitors may cause stability problems with some switching power supplies.

4.3.1.2 RS485
For remote control and communication with a host system the TMCM-1140 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.

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-1140
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 transceiver used on the PD-1140 units (SN65HVD3082ED) has just 1/8th of the
standard bus load and allows a maximum of 256 units to be connected to a single RS485 bus.
4.
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. In contrast to the
termination resistors this network is normally required just once per bus. Certain RS485 interface
converters available for PCs already include these additional resistors (e.g. USB-2-485).

4.3.1.3 CAN
For remote control and communication with a host system the TMCM-1140 provides a CAN bus interface.
Please note that the CAN interface is not available in case USB is connected. 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.

communication speeds, the bus should be properly terminated at both ends. The TMCM-1140
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 bus transceiver used on the TMCM-1140 units (TJA1050T) supports at least 110 nodes under
optimum conditions. Practically achievable number of nodes per CAN bus highly depends on bus
length (longer bus -> less nodes) and communication speed (higher speed -> less nodes).

For all digital inputs (IN_1, IN_2, IN_3) a 2k2 pull-up resistor to +5V can be activated. Then these
inputs have a default (unconnected) logic level of 1 and an external switch to GND can be
connected. This might be especially interesting in case these inputs are used as STOP_L /
STOP_R and HOME switch inputs (alternate function 1) or as encoder input for an external
incremental A/B/N encoder with open-collector outputs (pull-ups are not necessary for encoder
with push-pull outputs).

The eight pin connector of the TMCM-1140 offers two general purpose outputs OUT_0 and OUT_1. OUT_0
is an open-drain output capable of switching up to 1A. The output of the N-channel MOSFET transistors is
connected to a freewheeling diode for protection against voltage spikes especially from inductive loads
(relais etc.) above supply voltage (see figure below).
Note:
OUT_0 offers a freewheeling diode connected to VDD supply voltage. Therefore, this output should never

4.3.4 Mini-USB Connector
A 5pin mini-USB connector is available on-board for serial communication (as alternative to the CAN and
RS485 interface). This module supports USB 2.0 Full-Speed (12Mbit/s) connections.
CAN interface will be de-activated as soon as USB is connected due to internal sharing of hardware
resources.

Table 4.6 Connector for USB
For remote control and communication with a host system the TMCM-1140 provides a USB 2.0 full-speed
(12Mbit/s) interface (mini-USB connector). As soon as a USB-Host is connected the module will accept
commands via USB.
USB BUS POWERED OPERATION MODE
The TMCM-1140 supports both, USB self powered operation (when an external power is supplied via the
power supply connector) and USB bus powered operation, (no external power supply via power supply
connector).
On-board digital core logic will be powered via USB in case no other supply is connected (USB bus
powered operation). The digital core logic comprehends the microcontroller itself and also the EEPROM.
The USB bus powered operation mode has been implemented to enable configuration, parameter
settings, read-outs, firmware updates, etc. by just connecting an USB cable between module and host PC.
No additional cabling or external devices (e.g. power supply) are required.
Please note that the module might draw current from the USB +5V bus supply even in USB self powered
operation depending on the voltage level of this supply.
Motor movements are not possible in this operation mode. Therefore, connect the power connector and
change to USB self powered operation mode.

Reset to Factory Defaults
It is possible to reset the PD-1140 to factory default settings without establishing a communication link.
This might be helpful in case communication parameters of the preferred interface have been set to
unknown values or got accidentally lost.
For this procedure two pads on the bottom side of the board have to be shortened.
Please perform the following steps:

Power supply off and USB cable disconnected
Short two pads as marked in Figure 5.1
Power up board (power via USB is sufficient for this purpose)
Wait until the on-board red and green LEDs start flashing fast (this might take a while)
Power-off board (disconnect USB cable)
Remove short between pads
After switching on power-supply / connecting USB cable all permanent settings have been
restored to factory defaults
Short these two pads

On-Board LEDs
The board offers two LEDs in order to indicate board status. The function of both LEDs is dependent on
the firmware version. With standard TMCL firmware the green LED should be flashing slowly during
operation and the red LED should be off.
When there is no valid firmware programmed into the board or during firmware update the red and
green LEDs are permanently on.
