TRINAMIC Motion Control, now part of Maxim Integrated, has released the TMCM-1636, a single-axis servo controller, developed for drives up to 1,000 W and 60 A RMS. It’s suited for robotics, lab and factory automation, manufacturing, and patient handling equipment such as motorized beds and chairs.
The new module achieves high-current loop frequencies that minimize current ripple and enables the development of powerful drives with extremely high dynamics. It embeds two Trinamic motion control building blocks:
- The TMC4671 integrated servo controller with field-oriented control (FOC) for 3-phase PMSM / BLDC, 2-phase stepper motors, and dc motors
- The TMC6100 3-half-bridge gate driver for high voltage BLDC, PMSM, and servo motors
The module communicates through a CAN interface with either TMCL or CANopen protocols. The TMCL version has enough memory for up to 1,024 commands for standalone operation. This module can be programmed using the easy and intuitive TMCL-IDE, Trinamic’s free programming environment, to quickly set up and tune designs to reduce development time.
“Field oriented control, or vector control is a proven, efficient way to drive motors at optimal torque and velocity,” said Trinamic founder Michael Randt. “While it used to be a demanding task to implement FOC, many engineers use dedicated servo controller ICs. The TMCM-1636 further decreases development time and cost by offering a highly dynamic solution for powerful servo drives with the TMC4671’s integrated FOC.”
With the onboard TMC4671, the TMCM-1636 also offers a wide range of feedback systems, including two times ABN incremental encoder, analog encoder, digital HALL sensors, and SPI-based or RS422-based absolute encoders, depending on the firmware option. The module also supports +5 Vdc supply for external sensors. Further custom firmware options enable specific absolute encoder types interfacing via SPI or RS422.
The stacked board features an aluminum bottom plate with a total of seven M4 screw terminals for effective cooling. On top, it features one I/O and interface connector and one brake control output connector, allowing for compact designs with clean wiring. An integrated overvoltage protection output provides additional safety to your device.
The TMCM-1636 is now available in 24-V and 48-V versions with either CANopen or TMCL firmware with a choice of driver stages and customizable firmware and software.
