TMCM-1140

Stepper Motor Controller & Driver, 2A/24V, USB/CAN/RS485, 37x37mm

legacy product – for new designs please choose the TMCM-1240

The TMCM-1140 is an intelligent stepper motor controller/driver module featuring the new outstanding coolStep™ technology for sensorless load dependent current control. This allows energy efficient motor operation. With the advanced stallGuard2™ feature the load of the motor can be detected with high resolution. The module is designed to be mounted directly on a 42mm flange QMot stepper motor. It converts the motor into a compact mechatronic device with serial bus oriented or standalone control.

The PC based software development environment TMCL-IDE for the Trinamic Motion Control Language (TMCL™) can be downloaded free of charge from the TRINAMIC website. Predefined high level TMCL commands guarantee a rapid development of motion control applications. Communication traffic is kept very low since all time critical operations, e.g. ramp calculation are performed onboard.

A CANopen firmware is optionally available.
