20BD077A0AYNADD0

The Allen Bradley part number 20BD077A0AYNADD0 is classified as an AC drive, engineered to offer reliable performance for industrial motor control applications. This drive can sustain operating temperatures from -40 to 70 degrees Celsius, accommodating extreme environments. The device is rated for input frequencies of up to 47 Hz and provides encoder duty cycles around 50% ±10%.

In terms of voltage management, the unit delivers an output voltage that ranges from zero to the rated voltage of the connected motor. This drive boasts a displacement power factor of 0.98 across its entire speed spectrum, ensuring efficient energy use. Additionally, it has a substantial short circuit rating, reaching up to 200,000 A symmetrical, which enhances operational safety.

This model supports intermittent overloads, accommodating a 110% overload for up to one minute and a more significant 150% overload capability for durations of three seconds, catering to demanding operational loads. The analog input latency ranges from 4.8 to 12.4 ms when utilized in SVC motor control.

Operating with an input voltage range from 342 to 528V, the drive delivers its full power range of 460-528V at the 380-480V rating. It features torque regulation without feedback maintaining accuracy within ±5%, with a bandwidth of 600 rad/sec. For frequency control and speed regulation, it operates with slip compensation under a Volts per Hz mode, achieving 0.5% of base speed across a 40:1 speed range and maintaining a 10 rad/sec bandwidth.

The control method employed is a sine coded PWM with the option for a programmable carrier frequency. These ratings apply across all drives, and the system can be configured to operate as either a 6 pulse or 18 pulse drive as per engineering specifications.
