Aerotech’s XL4s network digital drive is a high-performance linear amplifier designed to drive single-phase motors and eliminate the non-linearities common with PWM amplifiers. The drive provides deterministic behavior, auto-identification, and easy software setup. The XL4s’ multi-core, double-precision floating point DSP controls the digital PID. System configuration is performed using all software-settable parameters including control-loop gains and system safety functions.
The XL4s has an encoder interpolation feature, dedicated analog and digital I/O, and separate power connections for motor and control supply voltages.
The XL4s is optimized to control single-phase motors or voice-coil axes like Aerotech’s TLG-4000 fast tool servo. 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, 192 kHz servo rates, and look-ahead-based velocity control.
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.
The XL4s exceeds other single-phase motor controllers due to an industry-leading servo rate of 192 kHz. 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.
