## **TRINAMIC FEATURES – CLOSED LOOP MODE** 

The TMCM-1311 is mainly designed to run 2-phase stepper motors in closed loop mode. It offers an automatic motor load adaption in positioning mode, velocity mode, and torque mode, which is based on encoder feedback and closed loop control software for analysis, error detection and error correction. 

The closed loop mode operation combines the advantages of a stepper driver system with the benefits of a servo drive. Thus, the TMCM-1311 is able to satisfy ambitious requirements in reliability and precision and can be used in several industrial demanding applications.

## **THE TRINAMIC CLOSED LOOP MODE OPERATION** 

- prevents the motor from stall and step loss caused by too high load or high velocity. 

- adapts the current amplitude to each motor load which is within the ranges predetermined by motor and controller/driver board characteristics. 

- achieves a higher torque output than in open loop mode. 

- guarantees a precise and fast positioning. 

- enables velocity and positioning error compensation. 

Using the TMCM-1311, energy will be saved and the motor will be kept cool.

## **3.2.8 CAN / RS485 Connector** 

The TMCM-1311 offers one 9-pin male D-SUB connector for CAN and RS485 communication. An on-board bi-stable relay allows switching between CAN and RS485 connector pin-assignment in software. This bistable relay remembers its state even when un-powered. Hence, the configuration of the pin-assignment for either CAN or RS485 has to be done only once. 

## **3.2.8.1 CAN Connector** 

If selected, a CAN 2.0B interface is available via the on-board 9-pin male D-SUB connector. Only three pins of the connector are used. The pin assignment of these three pins is in accordance with the _CiA Draft Recommendation Part 1: Cabling and connector pin assignment_ .

## **3.3 Power Supply** 

For proper operation care has to be taken with regard to power supply concept and design. The TMCM1311 includes about 40µF of supply filter capacitors. These are ceramic capacitors which have been selected for high reliability and long life time. Further, the module includes a 48V suppressor diode and additional varistor for over-voltage protection. 

## **CAUTION!** 

## _**Add external power supply capacitors!**_ 

The module contains a number of capacitors for power supply filtering. Nevertheless, depending on operation and selected motors the resulting capacity might be not large enough for proper supply buffering. Note: upper supply voltage limit must not be exceeded – not even for a short period of time! In this context it should be taken into account that the module will transfer energy from the motor back into the supply rail when the motor is working as generator e.g. during deceleration or brake conditions. In case the power supply capacitors are not sufficient for limiting power supply rising, additional measures have to be considered (e.g. suppressor diodes, brake resistor). Refer to chapter 3.3.1 for further information about adding electrolytic capacitors. 

_**Do not connect or disconnect motor during operation!**_ 

Motor cable and motor inductivity might lead to voltage spikes when the motor is disconnected / connected while energized. These voltage spikes might exceed voltage limits of the driver MOSFETs and might permanently damage them. Therefore, always disconnect power supply before connecting / disconnecting the motor. 

## _**Keep the power supply voltage below the upper limit of 52.5V!**_ 

Otherwise the driver electronics will seriously be damaged! Especially, when the selected operating voltage is near the upper limit a regulated power supply is highly recommended. 

## _**There is no reverse polarity protection!**_ 

The module will short any reversed supply voltage due to internal diodes of the driver transistors. 

## **3.3.1 Adding an Electrolytic Capacitor** 

TRINAMIC recommends connecting an electrolytic capacitor of significant size to the power supply lines next to the TMCM-1311. As rule of thumb, around 1000µF of capacity should be added for 1A of module power supply input current. 

The additional electrolytic capacitor 

- serves for power stabilization (buffer) and filtering. 

- reduces voltage spikes, which can occur in consequence of the combination of high inductance power supply wires and ceramic capacitors. 

**==> picture [473 x 207] intentionally omitted <==**

## **3.4 Communication** 

## **3.4.1 RS485** 

For remote control and communication with a host system the TMCM-1311 provides a two wire RS485 bus interface. The pins are shared with the CAN interface. Therefore, make sure the RS485 interface has been activated in software. 

To select a modules’ address, the TMCM-1311 is equipped with dip switches with digits from 1 to 4. Anyhow, the switches use the binary digit system. Thus, node addresses from 1 to 15 can be set. 

## **THERE ARE TWO POSSIBILITIES FOR THE ADDRESS SETTING** 

- _All DIP switches off_ : RS485 address is taken from the on-board non-volatile memory (EEPROM). Factory default value for the module address is 1. 

- _At least one DIP switch on_ : the 4 DIP switches define the RS485 address. The address is specified as binary 4bit value – DIP switches 1… 4 specify bit 1… 4 of the address 

**Figure 3.3 Dip switch for address selection** 

_Note_ 

- Per default, all dip switches are off and the module address taken from the EEPROM is 1. Per default, the host address is 2. 

- Do not use equal addresses for the host and the TMCM-1311! 

For proper operation, the following considerations 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. 

**==> picture [370 x 114] intentionally omitted <==**

**Figure 3.4 RS485 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-1311 does not integrate any termination resistor. Therefore, 120 Ω termination resistors at both ends of the bus have to be added externally. 

www.trinamic.com 

TMCM-1311 V1.2 Hardware Manual (Rev. 1.12 / 2013-JUL-05) 

15 

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 TMCM-1311 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 as 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 additional resistors (e.g. USB-2-485).

## **3.4.2 CAN** 

For remote control and communication with a host system the TMCM-1311 provides a CAN bus interface. 

To select a modules’ address, the TMCM-1311 is equipped with dip switches with digits from 1 to 4. Anyhow, the switches use the binary digit system. Thus, node addresses from 1 to 15 can be set. 

## **THERE ARE TWO POSSIBILITIES FOR THE ADDRESS SETTING**

- _At least one DIP switch on_ : the 4 DIP switches define the CAN address. The address is specified as binary 4bit value – DIP switches 1… 4 specify bit 1… 4 of the address 

**Figure 3.6 Dip switch for address selection** 

_Note_ 

- Per default, all dip switches are off and the module address taken from the EEPROM is 1. Per default, the host address is 2. 

- Do not use equal addresses for the host and the TMCM-1311! 

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.

## **Figure 3.7 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-1311 does not integrate any termination resistor. Therefore, 120 Ω termination resistors at both ends of the bus have to be added externally. 

3. _NUMBER OF NODES_ 

The bus transceiver used on the TMCM-1311 units (TJA1050T) supports at least 110 nodes under optimum conditions. In practice, the achievable number of nodes per CAN bus highly depends on the bus length (longer bus -> less nodes) and on the communication speed (higher speed -> less nodes).

## **3.4.3 USB** 

For remote control and communication with a host system the TMCM-1311 provides a USB 2.0 full-speed (12Mbit/s) interface. As soon as the USB-host is connected the module accepts commands via the USB interface. The TMCM-1311 supports USB _self powered operation_ with external power supply via the power supply connector and USB _bus powered operation_ without this external power supply. 

## **USB BUS POWERED OPERATION** 

During USB bus powered operation only the core digital circuit parts - microcontroller and EEPROM - are operational. Motor movements are not possible. This mode has been implemented in order to enable configuration, parameter setting, read-out, firmware updates, etc. by connecting an USB cable between the module and an USB-host. 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. This depends on the voltage level of this supply.

## **3.5 Inputs and Outputs** 

## **3.5.1 Encoder Input** 

The dedicated encoder connector offers support for the connection of an incremental encoder with a/b signals and optional n/index-channel. Encoders with +5V TTL, open-collector, or differential output signals can be connected directly. A +5V output - available at one connector pin - can be used for the encoder circuit supply. The on-board +5V switching voltage regulator has been designed in order to provide a maximum of 100mA for external circuits (shared with external encoder and reference switch circuit).

## **3.5.3 General Purpose Inputs** 

The TMCM-1311 has two I/O connectors with 8 inputs altogether including two dedicated analog inputs. All inputs offer the same basic input protection circuit, but digital and analog inputs have different input voltages: the digital inputs have been designed for +5V and +24V signal levels. The analog inputs have different input voltage dividers to support a full scale input voltage range of 0… +10V.

## **3.5.4 General Purpose Outputs** 

The TMCM-1311 offers two I/O connectors with 8 outputs altogether. All outputs are open-drain outputs and a freewheeling diode (to VDIGTAL) is already integrated. Six outputs are designed for currents up to 100mA and two outputs offer more powerful MOSFET driver transistors supporting currents up to 1A. 

If the VCC connection of the I/O connectors (connected internally to VDIGITAL) is used for the _supply of substantial current_ to any external circuit, make sure to connect VDIGTIAL to VDRIVER of the power supply connector.

## **6 Functional Description** 

The TMCM-1311 is a highly integrated single axis closed loop controller / driver module which can be controlled via USB, RS485, or CAN. Communication traffic is kept low since all time critical operations (e.g. ramp calculations) are performed on board. The preferred nominal supply voltage of the unit can be chosen out of 24V, 12V, and 48V DC. The module is designed for both, standalone operation and direct mode. Full remote control of the device with feedback is possible. The firmware of the module can be updated via the USB interface. 

In Figure 6.1 the main parts of the TMCM-1311 are shown: 

- the microprocessor, which runs the TMCL operating system (connected to TMCL memory) 

- the power driver with stallGuard2 and its energy efficient coolStep feature 

- the MOSFET driver stage 

- Encoder interface 

- USB, CAN and RS485 transceivers 

- On-board switching and linear voltage regulators for supply of on-board digital circuits
