TMCM-1321

Stepper Motor Closed-Loop Controller [&] Driver 0.7A/24V with RS485, 28×28

The TMCM-1321 is an easy to use, single axis controller/driver for 2-phase bipolar stepper motors with separate home and stop switch inputs. The built-in magnetic encoder can be used when a suitable magnet is attached to the motor axis, enabling also closed-loop operation. As an alternative, an optical encoder can be connected via digital ABN inputs. Different ramp shapes can be selected. Dynamic current control, and quiet, smooth and efficient operation are combined with StallGuard™ and CoolStep™ features.

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.
