Cycle time reduction and enhanced safety
- Efficient inbound/outbound logistics process
- Cost saving in design and development
- Short startup and maintenance times
- Enhanced safety
Solution
- 1. Efficient inbound/outbound logistics process with a high-accuracy positioning function
- Vibration control suppresses vibrations during acceleration/deceleration and stopping, and shortens the time needed for inbound/outbound.
- An optional S-curve acceleration/deceleration control allows high-speed operations with no collapse of cargo.
- 2. Contribute to cost reduction
- Programming load for high-order controllers can be reduced by incorporating positioning function in the inverter.
- The man-hours and maintenance cost can be reduced by modifying the parameter of the inverter.
- Effectively use of energy can be realized by returning regenerative energy to the power supply with the converter.
- 3. Improvement in safety
- Distributed control of the PLC and inverter realizes enhanced safety.
- Compliant with safety standards (standard compliance with PLd, SIL2).
