Rotary sensors

Incorporating the company’s Wide-Gap sensors, the M85 Thin-Line series of incremental encoders eliminates time-consuming alignment by providing a 57% larger operating gap between the magnetoresistive sensor and rotor, and a 50% increase in air gap tolerance as compared to conventional sensors. Edge-Guard protects critical sensor elements from accidental rotor contact and from contamination.

Servo-amplifier

The ACE1000 series “smart” digital brushless servo-amplifier uses DSP-based design architecture to provide software selectable torque, velocity and (optional) position mode operation. Sine wave commutation using encoder feedback provides smooth torque at low speeds. Optional software-selectable trapezoidal mode allows lower cost motor commutation and velocity control from Hall-effect feedback motors.

Amplifier

Designed to support the company’s line of precision servo motors, the AB5 amplifier linearizes the voltage to velocity profile at the amplifier level, thereby eliminating the need for custom servo algorithms. Thus, servo tuning and set up are like any DC servo motor. Motor static holding force can be turned on/off, allowing manual adjustment of linear or rotary mechanism as a teach mode.
