Aerotech’s XL4s high-performance voice-coil drive linear amplifier, conducive for closed-loop servo control of voice coil and single-phase motors, eliminates the non-linearities associated with PWM amplifiers and features a multi-core, double-precision, floating-point DSP that operates the digital PID. 

The XL4s includes:

• an encoder interpolation feature
• dedicated analog and digital I/O
• fiber-optic interface
• separate power connections for motor and control supply voltages

With the XL4s, you can achieve the following:

• industry-leading settling times
• long-term thermal stability
• sub-micron-level tracking accuracy with the following advanced features
  • full state feed-forward
  • 192 kHz servo rates
  • look-ahead-based velocity control

The XL4s provides better tracking errors and accelerated part quality in fast-tool servos, high-dynamic optical focusing axes, and high-speed pick-and-place machines.
