Aerotech introduces XL4s linear amplifier

January 9, 2019 - Aerotech’s XL4s linear amplifier is designed for closed-loop servo control of voice coil and single-phase motors, eliminating the non-linearities common with PWM amplifiers. The XL4s provides deterministic behavior, auto-identification, and software setup and features a multi-core, double-precision, floating-point DSP that controls the digital PID. All parameters are software-settable including control-loop gains and system safety functions. With the XL4s, userscan achieve settling times, thermal stability, and sub-micron-level tracking accuracy with features such as full state feed-forward, 192 kHz servo rates, and look-ahead-based velocity control.

The XL4s have a servo rate of 192 kHz. The XL4s has an encoder interpolation feature, dedicated analog and digital I/O, fiber-optic interface, and separate power connections for motor and control supply voltages.

The XL4s packaging allows it to be panel-mounted in a machine enclosure.
