Aerotech announced its XL4s linear amplifier, designed for closed-loop servo control of voice coil and single-phase motors.

This linear amplifier eliminates the non-linearities common with PWM amplifiers, and provides deterministic behavior, auto-identification, and features a multi-core, double-precision, floating-point DSP that controls the digital PID.

All parameters can be set using the accompanying software, including control-loop gains and system safety functions. The XL4sis capable of long-term thermal stability, and sub-micron-level tracking accuracy with advanced features such as full state feed-forward, 192 kHz servo rates, and look-ahead-based velocity control.

It also can improve tracking errors and part quality at high-speeds in applications such as fast-tool servos, high-dynamic optical focusing axes, and high-speed pick-and-place machines.

Additional Features:

Encoder interpolation

Dedicated analog and digital I/O

Fiber-optic interface

Separate power connections for motor and control supply voltages
