Transistor output (source type), typically 0~24V for magnetic particle clutches/brakes.

Built-in support for speed and length measurement through function combinations. Current drawn via the direct clutch/brake terminal exceeds 3

Compatible with various Mitsubishi powder clutches/brakes, making it suitable for both unwinding and rewinding applications.

The manual for the LE-30CTA outlines the wiring diagrams, but the practical utility lies in understanding how the controller processes this data. It utilizes PID (Proportional, Integral, Derivative) control algorithms to adjust the output. When a roll of material is unwinding, the diameter decreases, and the torque required to maintain tension changes. The LE-30CTA calculates these variations in real-time, sending precise signals to a magnetic powder clutch/brake or a servo motor drive. The operator's primary utility is recognizing that the controller is not just a switch, but a dynamic calculator constantly adjusting for physical variables like roll diameter and inertia.

Selecting the proper input for the Load Cell. Advantages of Using the LE-30CTA

In a manufacturing plant producing high-quality packaging materials, the production team was facing a significant challenge. Their existing tension control system was not providing the precise control needed, resulting in frequent material breaks, reduced production speeds, and increased waste.
