Product Description

The ABB ZCON-12 is the Main Control Unit (Control Board) for specific legacy ABB industrial DC drive systems, such often associated with the older Z Series or similar high-power converters. It is the central processing unit responsible for the drive’s fundamental operation.

The ZCON-12 is built around a microprocessor (often 16-bit) and is responsible for:

1. Executing Control Loops: Implementing algorithms for controlling motor speed, torque, and current.

2. I/O Handling: Processing both analog and digital signals for references, feedback, and status indications.

3. Firing Pulse Generation: Calculating and generating the precise firing pulses for the power section’s thyristors to regulate power flow to the motor.

4. Diagnostics: Monitoring the entire drive system for faults and activating safety shutdowns when necessary.

Product Parameters

Product Advantages

• Robust Control: Provides the core processing power necessary for the precise, fast-acting control required in high-dynamic industrial DC applications.

• Integrated Functions: Combines all critical control and protection logic onto a single board, simplifying the architecture of the drive system.

• Reliable Legacy Operation: The ZCON series was known for its robust, long-term performance in demanding environments, which is why many systems using it are still operational today.

• Dedicated I/O: The board contains dedicated input/output channels tailored specifically for DC motor control requirements (e.g., tacho feedback, field current reference).

Precautions

• Obsolete Status: The ZCON-12 is part of a highly obsolete and discontinued ABB drive series (Z Series). Sourcing replacement parts and obtaining manufacturer support can be extremely difficult.

• Expert Handling: Due to its age and criticality, any troubleshooting or repair of the ZCON-12 or its associated drive system should only be performed by highly experienced drive technicians.

• Power Isolation: The module operates within a high-power environment. ALWAYS ensure the entire drive is powered off, disconnected, and locked out before touching the control board.

• Firmware Dependency: Functionality is dependent on the specific firmware version loaded onto the board, which must match the requirements of the motor and application.

Product Applications

The ZCON-12 was used in systems designed for heavy industrial applications requiring high-power DC motor control:

• Metal Industry: High-torque control in rolling mills for steel and aluminum processing.

• Marine Applications: Used in older ship propulsion or crane control systems.

• Extrusion and Mixing: Providing variable speed and torque control for heavy-duty industrial machinery.

• Paper Machines: Used in line sections requiring precise speed synchronization between multiple motors.
