With the XL4s, you can achieve high industry 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. 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 packaging allows it to be panel-mounted in a machine enclosure.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Aerotech\u2019s 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.
