TRINAMIC / ANALOG DEVICES TMCM-1141 Stepper Motor Driver, 2-Phase, Single Axis, 1.1A, 24V DC Output, USB, RS485, S/D

The TMCM-1141 from Trinamic is a single axis stepper motor controller/driver module for sensorless load dependent current control. The device is powered by Trinamic stallGuard2�, coolStep� and spreadCycle� chopper technology and has a trapezoidal ramp generator. The TMCM-1141 is capable of driving up to 1.6A of current from each output (with proper heatsinking). The device provides a RS485, USB, S/D interface. It features motor current up to 1.1A RMS/1.6A peak (low current range, programmable) (or 2A RMS/2.8A peak (high current range, programmable, new additional range since hardware version 1.3). An integrated protocol processor supplies a high level TMCL communication, offers a convenient handling and can be used in many decentralized applications.

• Supply voltage range from 9V to 28V ( 24VDC nominal )
• Motion profile calculation in real time
• On the fly alteration of motor parameters (position, velocity, acceleration)
• High performance microcontroller for overall system control, serial communication protocol handling
• Up to 256 microsteps per full step
• High efficient operation and low power dissipation
• Dynamic current control, integrated protection, stallGuard2 feature for stall detection
• Feature coolStep for reduced power consumption and heat dissipation
• Dimension is 37mm x 37mm x 12mm (L x W x H)
