1. AC voltage, Bus supply / load may result in significantly lower maximum peak currents.
2. Peak and continuous output current is load dependent. The controller will limit its output current based on velocity
and motor resistance.
3. Selectable through parameters.

(1) This specification depends on the motor supply voltage, the motor speed, and motor resistance. Contact an Aerotech
sales engineer for more information.
(2) This specification assumes that an AC or DC motor type with a 0 Ω winding resistance is used.
(3) The first number is for a stationary AC or DC motor. The second number is for an AC motor that is in motion.
(4) The specification will de-rate when the ambient temperature exceeds 25°C.
(5) The XSL3 amplifier has circuitry that will limit peak power to protect itself from damage. In the Status Utility, the
Power Limiting bit under Drive Status monitors the condition of the circuitry. If the circuit is open, the Power Limiting bit
will show as "ON".
(6) All linear amplifier (XSL3-10-40) specifications assume that the fan tray is installed, the fans are set to full-speed
mode, and the ambient temperature is 25°C.
(7) The transistor temperature can be up to 25°C higher than the heat sink temperature that is shown in the Status
Utility. Set the AverageCurrentFault parameter to ensure that the heat sink power dissipation is not exceeded.
(8) Aerotech recommends that you do not use high-current stepper motors with the XSL3-10-40 linear amplifier because
of high-power dissipation. Contact Aerotech for additional information.
