Lithium-Ion Battery

• Winding multiturn cam
• High-accuracy cutting
• Dancer VCM drive

Line fluctuations can be suppressed by matching winding circumferential speed to material feed rate using dedicated Function Block.

• Use teaching to automatically generate correction cam table for matching winding rotation speed to material feed rate.
• The generated cam table enables winding rotation speed correction linked to feed rate.

High-accuracy cutting can be achieved by applying corrections for synchronisation encoder error using high-speed touch probe built into servo amplifier.

1μs accuracy of MELSERVO MR-J5 amplifier's touch probe enables high-accuracy correction of position detection error.

Tension fluctuation suppression and tension accuracy improvement can be achieved by employing VCM (Voice Coil Motor) in the dancer roll pressurisation mechanism.

• Dancer mechanism inertia and material pressurisation force fluctuations can be reduced.
• Our servo amplifiers can drive VCM motors from Akribis, etc.
