Closed-loop servo control for voice-coil and single-phase motors
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 behaviour, auto-identification, and easy 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, you can achieve industry-leading settling times, long-term thermal stability, and sub-micron-level tracking accuracy with advanced features such as full state feed-forward, 192kHz servo rates, and look-ahead-based velocity control.
The XL4s exceeds other single-phase motor controllers due to its servo rate of 192kHz. This directly correlates to better 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. The XL4s has an encoder interpolation feature, dedicated analogue and digital I/O, fibre-optic interface, and separate power connections for motor and control supply voltages.
Unlike other fast tool servo controllers, the XL4s packaging allows it to be panel-mounted in a machine enclosure, resulting in a smaller machine footprint and requiring less overall floor space.
