The easy to use three-axes plug-in TMCM-3230 module extends Trinamic’s OEM line.

The evolution of technology is transforming all industries, including motion control. Following components that become increasingly faster, cheaper, more powerful and much smaller, TRINAMIC Motion Control announces the TMCM-3230. A highly miniaturized, technologically leading-edge stepper driver unit, it can be easily plugged into a customized baseboard offering a single 68-pin connector.
A demand for compact, decentralized devices instead of huge machines is driving this general trend towards miniaturization. “For many manufacturers, small and decentralized devices enable leaner processes and reduce storage and logistics cost,” explains Trinamic’s CEO Michael Randt. This trend is visible in all kinds of applications such as microbiology instrumentation, lab automation, scientific test equipment and micro precision systems – which is why Trinamic developed the credit card sized plug-in module TMCM-3230.
Measuring only 80mm x 50mm, the cost-efficient TMCM-3230 embeds advanced motor control functions, motion control and PLC features like all other TMCM modules. Host communication is possible using the serial UART interface (with a standard RS232 or RS485 level shifter) or using the optional CANopen (CAN controller is already integrated on the board). Together with the free and easy to use TMCML-IDE, the module allows for easy implementation of a standalone program flow and remote-controlled operation.
Designed for an operating voltage of +12V to +24V DC nominal at 1A RMS phase current, the new module offers leading-edge current control technologies based on Trinamic’s latest stepper motor driver generation. A high-resolution microstepping with up to 256 equidistant microsteps per full-step generates a total resolution of 51.200 steps per rotation, resulting in vibration-free positioning. With Trinamic’s stealthChop™ current control for silent positioning at low speed and spreadCycle™ for highest performance at high speed, the module provides superior performance wherever small stepper motors are used.
An integrated sixPoint™ ramp generator per axis allows for precise and rapid positioning – even in environments where parameters and target positions must be changed during motion. The module has L+R reference switch inputs for every axis and comes with stallGuard2™ for sensorless homing.
The fully integrated hardware motion controller TMCM-3230 is immediately available through distribution at a single unit recommended resale price of USD 124.
