Features
The TMCM-1021 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 can be mounted on the back of NEMA 11 (28mm flange size)
stepper motors and has been designed for coil currents of up to 0.7A RMS and 24V DC supply voltage.
With its high energy efficiency from Trinamic’s coolStep™ technology cost for power consumption is kept
down. The TMCL firmware allows for standalone operation and direct mode control.
Main characteristics
• Motion controller & stepper motor driver:
–
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.
• Encoder
–
sensOstep™ magnetic encoder with 1024 increments per round.
–
Usable for example for step-loss detection under all operating conditions and positioning
supervision.
• Interfaces
–
RS485 bus.
–
Up to four general-purpose digital inputs (two shared with general purpose outputs).
–
Two general purpose outputs.
–
Step/Direction input (shared with the general purpose inputs).
Software
TMCL remote controlled operation via RS485 interface and/or stand-alone operation via TMCL program-
ming. PC-based application development software TMCL-IDE available for free.
Electrical data
• Supply voltage: +24V DC nominal (10. . . 27V DC supply range).
• Motor current: up to 0.7A RMS / 1A peak (programmable). Since hardware V1.4 also 1.4A RMS / 2A
peak programmable (new extended range since hardware V1.4).
