These modules from Trinamic are complete embedded motion control solutions that also retain the potential for customisation. They are ready to use and can be easily integrated into the user application and at an amazing unbeatable price/performance ratio.

The TMCM-110-42 is an intelligent stepper motor controller and driver module designed to be mounted directly on a 42mm flange motor. The module converts the motor into a compact mechatronic device with bus oriented or stand-alone control.

The motor, switches, power and the multi purpose I/O’s can be connected with small plug in connectors. It comes with the PC based software development environment TMCL-IDE for the Trinamic Motion Control Language (TMCL™). Using predefined TMCL™ high level commands like ‘move to position’ or ‘constant rotation’ a rapid and fast development of motion control applications is guaranteed. There are two inputs for reference, stop switches and one general purpose digital or analogue input and one output.

The TMCM-110-42 can be controlled via an RS-232, RS-485, I²C or CAN interface and communication traffic is kept very low since all time critical operations, e.g. ramp calculation are performed onboard. The programme can be stored in the on board EEPROM for stand-alone operation; furthermore the firmware of the module can be updated via the serial interface. With the clever stallGuard™ feature it is possible to detect motor overload or motor stall without the need for an encoder.

The main features include, up to 16 times microstepping, memory for 2048 TMCL™ commands, automatic ramp generation in hardware and on the fly alteration of motion parameters (e.g. position, velocity, acceleration). There is in addition stallGuard™ option for sensorless motor stall detection, full step frequencies up to 20kHz, dynamic current control and due to TRINAMIC driver technology no heatsink required.

The module is available on its own or together with a 42mm motor (NEMA 17) as mechatronic solution named PANdrive PD-110-42. The motor supply voltage is 7V to 34V and up to 1.1A coil current RMS (1.5A peak). Three different motor sizes are available.
