Stepper drives detect stalls in open-loop control mode
Titanio series stepper drives from Ever Motion Solutions include three new drives available with two open-loop (no encoder feedback) models and one open/closed-loop version (a motor-mounted encoder provides position feedback to the drive). They also work seamlessly with AutomationDirect’s SureStep stepper motors. Unlike typical stepper drives, Titanio can detect stalls in open-loop control mode by monitoring the motor’s back EMF. This lets system designers take advantage of stall detection without the hassle and expense of a closed-loop system.
Titanio uses sinusoidal current control to provide smooth motor movement, with reduced audible noise, vibration and resonance dampening, higher system efficiency (less heat), and increased and more consistent torque output at all speeds.
Titanio’s LW3A model stepper drive is a high-bus-voltage unit that accepts 100-240 VAC power input and is compatible with all STP-MTRACx series high-bus-voltage stepper motors. While basic, dip-switch setup is possible for all models, optional Ever Studio configuration software (free download) allows advanced configuration of LW3A and LW4D, including setup of additional micro-stepping resolutions. It even allows jogging/indexing and a built-in oscilloscope for tuning and debugging LW4D.
