Improving tension stability for sudden acceleration
Dancer VCM drive
Solution details
Stabilising line for non-round winding shafts
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.
Improving accuracy for electrode cutting length
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.
Improving tension stability for sudden acceleration
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.
