1. Solution Overview :
In a coil unwinding and slitting line, the two key units that determine product quality are:
- Slitting unit → cuts the strip to the required width
- Recoiler → rewinds the material after slitting
🔧 This upgrade project uses:
2. Role of Each Drive in the System :
🔵 DC590P 270A – Recoiler Control
👉 This is the most critical unit for tension control
Main functions:
- Controls torque to maintain stable tension
- Automatically increases torque as the coil diameter grows
- Provides regenerative braking during deceleration
Technical features:
- 4Q operation (motoring + braking)
- Torque / tension control mode
- Suitable for heavy loads with high inertia
Product code: 590P-53327032-P00-U4V0
🟠 DC590P 180A – Slitter Control
👉 The slitting unit requires stable speed and synchronization with the main line
Main functions:
- Controls the slitting shaft speed
- Synchronizes with the main line speed
- Maintains stability under load variations (different material thicknesses)
Features:
- High-precision speed control
- Fast response
- Reduces vibration and blade misalignment
Product code: 590P-53318032-P00-U4V0
3. Control Principle After Upgrade :
The system operates based on the following model:
⚙️ Slitting unit (Master or speed follower)
- Receives the line speed reference
- Maintains stable cutting speed
⚙️ Recoiler (Torque control + tension loop)
- Controls based on tension
- Compensates according to coil diameter (via diameter calculation or feedback)
👉 The two drives are interconnected via:
- Analog signals (speed reference / torque reference)
- Intermediate PLC
4. Benefits After the Upgrade :
🎯 Significantly improved product quality
- Clean cut edges, no burrs
- Even and well-aligned recoiling
⚡ Smooth and stable machine operation
- No jerking during speed changes
- No mechanical shock
🔧 Easy maintenance
- DC590P is widely available
- Easy replacement and setup
💰 Reduced defects – increased productivity
- Less scrap
- Reduced downtime
5. Strengths of the DC590P Solution :
✔ Highly accurate torque control for the recoiler
✔ Excellent speed synchronization for the slitting unit
✔ Supports PID tension control
✔ 4-quadrant operation (regenerative braking)
✔ Ideal for retrofitting existing machines
