Ever Motion Solutions^® Titanio series drives are high performance vector stepper drives that provide industry-leading quality and control. All Ever drives support open loop (no encoder feedback). The LW4D also supports closed loop control (motor mounted encoder provides position feedback to the drive). Like most closed loop stepper drives, the LW4D drive can alert the upper control system if a motor stalls or 'skips a step' (stall detection). Furthermore, the Titanio drives also have stall detection capability in open loop control mode: the drives use the motor's back EMF to monitor motor movement. This means the Titanio drives can detect and report motor stalling without encoder feedback.

• Support for pulse & direction, or CW/CCW pulse inputs
• Microstep resolution: 200-51200ppr (LW3D) 200-65536ppr (LW4D and LW3A)
• Monitoring of motor back EMF enables step loss detection without an encoder
• Proprietary, patented algorithms use sinusoidal current control to:
  • Reduce parasitic phase current harmonics
  • Reduce audible motor noise
  • Smooth motor movement, regardless of microstep resolution
  • Damp motor vibrations and resonances
  • Reduce heating and increase efficiency of the motor and drive
• Increased positioning accuracy
• Better and more constant torque output at all speeds
• Protection against short circuit and open circuit
• Alarms for over/under voltage, temperature, short circuit
• Basic setup with DIP switches
• Advanced software setup (optional for LW4D and LW3A drive) with FREE (downloadable) software
• Open-loop modes work with SureStep 14, 17, 23, 34, and 42 frame size motors
• Closed-loop drive (LW4D) is preconfigured for select SureStep encoder-mounted (E) motors and encoder-ready (D) motors
