The XL5e’s superior performance and thoughtful design set it apart from other linear amplifiers. A highly integrated design means you have control and bus power supplies, servo and current controllers, linear power amplifiers, cooling fans and heatsinks in a single package. The XL5e’s performance is driven by high-end components that enable zero amplifier “dead time” and high-resolution, low-noise current sensing. As a result, you’ll see more accurate position tracking, more precise in-position stability and smaller minimum step sizes.

Standard features for the Automation1 XL5e include safe torque off (STO), a data array with more than 67 MB of memory, digital and analog I/O, Position Synchronized Output (PSO), dedicated home and end-of-travel limit inputs and an enhanced current sense device.

The standard XL5e accepts square-wave and absolute encoder feedback signals. With the optional encoder multiplier feature, sine-wave encoders can be multiplied by up to 65,536, making XL5e our highest-resolution position feedback drive. Dual-multiplied and dual-absolute encoder feedback is supported.

The XL5e is more than a motion control device. It also includes many process control features. Empowered with Aerotech’s PSO functionality, a single-axis XL5e can track up to three encoders in real time to trigger a process tool like an industrial laser or camera.   Each XL5e can be configured with an optional I/O expansion board, greatly increasing the number of I/O points. The I/O board includes a dedicated PSO output, and PSO can be used with a synchronization input to synchronize process control with an external mode-locked frequency input.

Linear amplifiers are characterized by low noise operation, and the XL5e is no different.  This is because linear amplifiers do not incorporate on-off pulse width modulation (PWM) switching to control motor currents.

Two HyperWire connections make it simple to connect the XL5e with other Automation1 drive hardware in a multi-axis configuration. A 24-volt, one amp brake output is included. The device is CE approved, NRTL safety certified and EU 2015/863 RoHS 3 directive certified. The power amplifier bandwidth is software selectable.

1. AC or DC motor type with a 0 Ω winding resistance assumed.
2. The first value is for a stationary AC or DC motor. The second value is for a moving AC motor.
3. Derate at temperatures above 25°C ambient.
4. Amplifier power dissipation is calculated as (Vbus – Vout) · Iout for each phase. A 40B configuration that drives 1 A into 0 Ω results in 40 W of power dissipation in the amplifier.
5. The XL5e amplifier has peak power-limiting circuitry to protect itself from damage. The power limiting bit in the drive status word indicates if this has occurred.
