The Allen Bradley 1391-126399 drive board is an essential component of the AC Servo 1391 series, known for its logic control capabilities. It operates with an input voltage specification of 230 VAC ±10%, making it suitable for various applications. Frequency operation is supported in the range of 47 to 63 Hz, ensuring compatibility with a wide range of power systems.

When operating, the board delivers an output voltage controlled via PWM, varying from 0 to 230 VAC. Its continuous output current is rated at 15 A, with a temporary peak output current capability of 30 A, achievable for three seconds. Feedback from the motor is processed through a resolver, which is the standard for ensuring reliable performance in motor control.

Input control is manageable with six digital inputs, along with four digital outputs that provide feedback or control signals. For analog commands, the drive accepts differential input voltages of ±10 V. It operates with a switching frequency of 4 kHz, optimizing response times.

For protective features, the board has a trip response time of less than 10 ms, enhancing safety during operation. Isolation between control and power sections is rated at 1500 V, while the dielectric strength reaches 2000 V RMS, ensuring robust performance in potentially noisy electrical environments. This drive board provides an efficient solution for precise motor control and feedback in various automation applications.
