The single axis TMCM-1180 features the unique coolStep™ technology

The TMCM-1180 is an intelligent stepper motor, single axis controller/driver module using the new outstanding coolStep™ technology for sensorless load dependent current control. This allows for the first time an energy efficient operation of an open-loop stepper motor system. With the advanced stallGuard2™ feature the load of the motor can be detected with high resolution.

TCMC-1180The module is designed to be mounted directly on an 86mm flange (NEMA34) QMot stepper motor. It converts the motor into a compact mechatronic device with bus oriented or stand-alone control. The motor, switches, power and the multi purpose I/Os can be connected with small pluggable connectors.

The TMCM-1180 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.

The TMCM-1180 can be controlled using a serial interface and communication traffic is kept very low since all time critical operations, e.g. ramp calculation are performed onboard. The TMCL™ programme can be stored in the on board EEPROM for stand-alone operation and the firmware of the module updated via the serial interface. (As an option there is CANopen firmware available)

The drive runs up to 5.5A coil current RMS with 24 to 48V DC (nominal) supply voltage able to support two-phase bipolar stepper motors. The interfaces available are USB, CAN, RS-232 or RS-485 serial interface and step/direction/enable inputs (with optical coupling)

Other features include up to 256 times microstepping (51200 steps/rev), with a 1,8° stepping motor and a memory for 2048 TMCL™ commands. In addition there is automatic ramp generation in hardware and on the fly alteration of motion parameters (e.g. position, velocity, acceleration) 

Still further features include the stallGuard2™ sensorless high resolution motor load detection, spreadCycle™ chopper for improved smoothness and high speed operation, microPlyer™ internal microstep multiplier  (16 to 256 µSteps) for lower frequency on step input and integrated absolute sensOstep™ encoder chip (max. 256 count per rev)
