(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) De-rate 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.
