The controller stores the current sensor tare weight as 0.00 kN/N. Step 2: Span Calibration

For DIN rail mounting, ensure adequate clearance around the unit for airflow and wiring access. When mounting in a control cabinet, verify that internal cabinet temperatures remain within the specified 0–40°C operating range.

Used when the controller interfaces with an external inverter drive instead of a mechanical brake. 3. Step-by-Step Initial Setup & Calibration

If tension is unstable, check the grounding and check for interference from high-power cables.

The Mitsubishi LE-30CTA is an automatic tension controller designed for web materials, utilizing feedback control and dual output options to manage torque for clutches and brakes. It features operation memory for storing multiple data types, along with taper tension and inertia compensation for precise, consistent performance.

Connect the main AC power source (100V–240V). Install a 3A fuse on the hot line for overcurrent protection.
