The 20AD040C3AYNARC0 is a PowerFlex 70 AC Drive created by Allen-Bradley. Belonging to Series A, this AC drive features a current rating of 40 Amps, operates at 480 Volts AC, and works across 3 phases. It delivers 22 kW of power and includes a full numeric LCD interface, a braking system, enhanced control capabilities, and supports the ControlNet (Coax) network. Housed in a Frame D NEMA/UL Type 4X/12 Enclosure, it undergoes auto-tuning to verify hardware settings using the start-up menu on the human-machine interface module.
Operators can use an auxiliary power source to keep control systems active even when main power is off, ensuring the control chassis, feedback option cards, and controller remain operational. The drive allows for the selection between dynamic braking, bus regulation, or a combination of both. It includes an instant overcurrent trip feature that activates when the output current surpasses a set limit. Datalinks enable the transfer of I/O data from a communication adapter to a controller.
Motor power values are indicated with positive numbers for motoring power and negative numbers for regenerative power. The drive also features a torque follower, which can result in a higher torque command when the load is disconnected. Additionally, it includes a point-to-point motion planner for executing precise movements using a trapezoidal motion profile.
