Electrical Specifications

The electrical specifications for the drive rack are listed in Electrical Specifications and the electrical specifications for the servo amplifiers in PWM Amplifier Electrical Specifications (XSP3/XSP3+) and Linear Amplifier Electrical Specifications (XSL3).

IMPORTANT: These electrical specifications represent the maximum capability of a feature. System constraints can result in lower performance. For example, the motor output specifications are affected by the Bus supply, the number of axes that are operating at the same time, the type of motion, the AC Line voltage, and motor requirements.

The power label shows the factory-configured AC power requirements (iXR3/XR3 AC Power Label Location).

DANGER: Update the AC power label if you reconfigure the AC Input Voltage.

(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 a motor winding resistance of 0 Ω.

(3) The first number is for a stationary AC or DC motor. The second number is for an AC motor that is in motion. The third number is for a stepper motor.

(4) The specification will de-rate when the ambient temperature exceeds 25°C.

NOTES: 

  • 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".

  • All XSL3 amplifier specifications assume that the fan tray is installed, the fans are set to full-speed mode, and the ambient temperature is 25°C.

  • The transistor temperature can be up to 25°C higher than the heat sink temperature that is shown in the Status Utility. Set the AverageCurrentThreshold parameter to ensure that the heat sink power dissipation is not exceeded.

  • Aerotech recommends that you do not use high-current stepper motors with the XSL3 linear amplifier because of high-power dissipation. Contact Aerotech for additional information.
