1391-DES45 Printed Circuit Board  

Product Details Introduction

1391-DES45 Printed Circuit Board (Servo Drive Core Board)

1391-DES45 is the core control and power drive PCB of Rockwell Allen Bradley 1391-DES series single axis digital AC servo drive, specially designed for 1326 series servo motors, and is a key component of industrial closed-loop positioning systems.

Product positioning: Integrated printed circuit board for main control and power drive of 1391-DES series 45A servo drive.

Compatible motor: Specially designed for Allen Bradley 1326 series AC servo motors, supporting speed/torque/position closed-loop control.

Rated current: Continuous output current of 45A RMS, peak current of 90A RMS.

Power specification: Continuous output of 14-15kW (19-21HP), peak output of 30kW.

Electrical input: three-phase 230V AC, 50/60Hz, input current of approximately 38A.

Electrical output: Three phase 0-210V AC, 0-200Hz, drives servo motor operation.

Core functions: PWM power drive, current/speed loop closed-loop regulation, encoder signal acquisition and processing.

Feedback support: Compatible with AQB encoders (256-2048 lines/rev), providing high-precision position feedback.

Protection mechanism: Integrated multiple protections such as overcurrent, overvoltage, undervoltage, overheating, and encoder failure.

Control interface: Supports DI/DO digital and analog input, encoder output, and communication ports (such as DeviceNet).

Application scenarios: high-precision positioning applications such as machine tools, automated production lines, robots, packaging equipment, etc.

Physical characteristics: Multi layer PCB design, integrated IGBT, driver IC, sampling circuit, protection circuit, with heat dissipation substrate.

Status indication: onboard LED, displaying status such as operation, fault, encoder, communication, etc.

Product status: The original factory has ceased production, and the market mainly consists of second-hand, refurbished, and repair spare parts.

Alternative solution: Upgrade to Allen Bradley Kinetix 5500/6500 series servo drives, compatible with new motors and controllers.

In summary, 1391-DES45 is the core PCB of the 1391 series 45A servo drive, responsible for power output and closed-loop control. It is a key spare part for existing industrial equipment, and faults often manifest as alarms, no output, overcurrent, etc. It is recommended to replace or upgrade the entire board for maintenance.
