• Large-capacity vector inverter
• Roll press droop control
• Stable high-accuracy tension control

The FR-A800 inverter series lineup includes standard products from 0.4 to 500 kW, and can support vector control by installing dedicated vector motors and vector control I/F.

When using vector control:

• Speed response: 130 Hz
• Speed variation: ±0.01%

Dedicated droop control Function Block (FB) for roll presses performs correction of slave rolls to counter torque deviations due to differences in circumferential speeds of top and bottom rolls.

The system can handle interference torque in the high-speed region and speed fluctuations in the low-speed region.

Stable high-accuracy tension control can be easily achieved using tension controllers. Torque control of powder clutches/brakes, AC servos, and vector inverters are all supported

• For powder clutches, tension control is possible from almost-stopped line speeds
• Tension fluctuations during acceleration are suppressed by calculating the material's moment of inertia and line speed.

Detect metal particles on foil surfaces as early as possible to prevent low yield downstream. Detecting these particles with Line Scan Bars at an early stage ensures machine integrity.

• Use Line Scan Bar camera technology with adjustable illumination to detect foreign metal particles.
• Edge detection and high precision measurement of coating width.
