KG TMCM-3314, TMCM-3315 Hardware Manual (V1.11 / 2019-JUL-23) 6 ## **4 Mechanical and Electrical Interfacing** ## **4.1 Dimensions and Mounting Holes** The dimensions of the TMCM-3314 and TMCM-3315 controller/driver board are approx. 280mm 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-3314 / TMCM-3315 and position of mounting holes** Please note: TMCM-3314 and TMCM-3315 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. Copyright © 2016-2019, TRINAMIC Motion Control GmbH & Co. KG TMCM-3314, TMCM-3315 Hardware Manual (V1.11 / 2019-JUL-23) 7 ## **4.2 Board mounting considerations** The TMCM-3314 / TMCM-3315 offer 12 metal plated mounting holes. One hole (close to power supply connector) is connected to on-board system ground (connected to power supply input ground) via 1M (500VDC) || 1nF (1kV). The same combination of resistor and capacitor is used for connecting the RJ45 shield ground (connector enclosure) to power supply input ground (see figure 4.2). **Figure 4.2 TMCM-3314 / TMCM-3315 mounting hole connections** 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! Copyright © 2016-2019, TRINAMIC Motion Control GmbH & Co.

A two pin Molex MicroFit™ connector (Molex part no. 43650-0215) is used for connecting an external brake resistor. The brake resistor output will be switched on at about 52V power supply voltage.

An external power resistor should<br>be connected between Pin 1 and Pin 2 of this connector.| **Table 5.16: Power supply brick: Resistor connector** ## **5.5 Power supply** For proper operation care has to be taken with regard to power supply concept and design. The TMCM-3314 / TMCM-3315 includes about 6000µF/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-3314 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-3314 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. Copyright © 2016-2019, TRINAMIC Motion Control GmbH & Co.

The TMCM-3314 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-3314 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-3314 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): **==> picture [379 x 138] intentionally omitted <==** **----- Start of picture text -----**<br> Slave Slave<br>node node +5V<br>n - 1 n<br>pull-up (680R)<br>termination RS485+ / RS485A termination<br>resistor resistor<br>(220R) RS485- / RS485B (120R)<br>pull-down (680R)<br>GND<br>**----- End of picture text -----**<br> **Figure 4.4: Bus lines with resistor (Bias) network on one side, only** Or add resistor (Bias) network at **both** ends of the bus (like Profibus™ termination): Copyright © 2016-2019, TRINAMIC Motion Control GmbH & Co.

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-3314 offers two connectors (RJ45) which are connected directly to each other and the on-board CAN transceiver.

KG TMCM-3314, TMCM-3315 Hardware Manual (V1.11 / 2019-JUL-23) 27 ## **10 TMCM-3314 Functional Description** The TMCM-3314 is a highly integrated controller/driver module for 3 stepper motor axes with (optional) closedloop operation. The unit may 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 24V or 48V 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-3314 are shown: - Microcontroller, responsible for overall control – executes the firmware (either TMCL or CANopen incl. the communication stack) - 3 motion controller and driver (based on the TMC4361 motion controller and the TMC5160 stepper driver Ics) with additional higher-power MOSFET stepper motor driver stage. With the integrated motion controller (TMC4361) calculation of ramps (linear / S-ramp), speed profiles and optional closed-loop operation with external encoder is done internally in hardware - interface for an external (e.g. optical) incremental A/B/N encoder (differential RS422 signals) for each axis (High-resolution encoder required for optional closed-loop operation) - interface for HOME / REFL / REFR reference switches for each axis - 4 general purpose analog / digital inputs - 4 general purpose digital (open-drain) outputs - Three serial communication interfaces: CAN, RS485 and USB (Micro-USB-connector) **Figure 10.1 Main parts of the TMCM-3314** Copyright © 2016-2019, TRINAMIC Motion Control GmbH & Co.
