The TMCM-1311 is mainly designed to run 2-phase stepper motors in closed loop mode. It offers an automatic 
motor load adaption in positioning mode, velocity mode, and torque mode, which is based on encoder 
feedback and closed loop control software for analysis, error detection and error correction.  
 
The closed loop mode operation combines the advantages of a stepper driver system with the benefits of a 
servo drive. Thus, the TMCM-1311 is able to satisfy ambitious requirements in reliability and precision and 
can be used in several industrial demanding applications. 
 

  Benefits of Stepper Drive

  High torque without gearing
  No feedback loop oscillations
  High precision
  Precise velocity control

  Benefits of Servo Drive

  Reaction to any impact
  No position loss
  Torque control

­

 

prevents the motor from stall and step loss caused by too high load or high velocity. 

­

 

adapts the current amplitude to each motor load which is within the ranges predetermined by motor 
and controller/driver board characteristics. 

­

 

achieves a higher torque output than in open loop mode. 

­

 

guarantees a precise and fast positioning. 

­

 

enables velocity and positioning error compensation. 

 
Using the TMCM-1311, energy will be saved and the motor will be kept cool.
