1 Features

The TMCM-1270 is a single axis controller/driver module for 2-phase bipolar stepper motors with state

of the art feature set. It is highly integrated, oﬀers a convenient handling and can be used in many

decentralized applications. The module has been designed for coil currents up to 1A RMS and 24V DC

supply voltage. Three digital inputs can be conﬁgured as home and endstop switches or incremental

encoder inputs. With its high energy eﬃciency from TRINAMIC’s coolStep

™

technology cost for power

consumption is kept down. The TMCL ﬁrmware allows for both standalone and direct mode operation.

Main characteristics

• Motion controller & stepper motor driver:

– Hardware motion proﬁle calculation in real-time

– On the ﬂy alteration of motion parameters (e.g. position, velocity, acceleration)

–

High performance microcontroller for overall system control and communication protocol

handling

– Up to 256 microsteps per full step

– High-eﬃcient operation, low power dissipation

– Dynamic current control

– Integrated protection

– stallGuard2™ feature for stall detection

– coolStep™ feature for reduced power consumption and heat dissipation
