FAQ

 

 

Q: What is the average commissioning time for a standard cell?

A: Factory installation and on-site commissioning require 5 to 10 working days, depending on utility connections and foundation readiness.

Q: Can the system integrate with existing ERP or MES software?

A: Yes. The cell controller supports standard industrial protocols including OPC-UA, Modbus TCP, and Ethernet/IP for production data transfer.

Q: What is required to set up offline programming (OLP)?

A: OLP requires 3D CAD models of the workpiece, fixture tooling, and torch geometry. We provide the calibrated kinematic robot model for direct import into your simulation software.

Q: How are remote diagnostics managed?

A: Systems include an industrial-grade VPN router enabling secure, encrypted remote access by our engineering team for PLC and controller diagnostics.
