Retrofit Scope

A TRUMPF control retrofit modernizes an aging laser cutting machine with a Bochu platform after drive, I/O and safety compatibility review.

Controller, bus and servo compatibility review
I/O mapping and electrical cabinet update
CypCut configuration, safety validation and training

TRUMPF laser control cabinet being rewired for a CypCut retrofit — TRUMPF-to-CypCut retrofit: mapped control cabinet and motion interfaces.

Existing control diagnosis

This survey identifies the installed TRUMPF control, drive feedback, remote I/O, safety chain and process signals so that every retained interface is documented before the CypCut control cabinet is specified.

Trace servo command, encoder feedback and limit-switch circuits at the cabinet.
Record laser enable, gas, height-control and auxiliary process I/O.
Verify safety relays, door circuits and reset behavior with the machine stopped.

CypCut control architecture

The retrofit replaces the obsolete control path with a Bochu/CypCut platform while retaining only interfaces proven compatible. Cabinet terminals, motion feedback and field wiring are remapped against an approved electrical design.

Build an I/O cross-reference from TRUMPF functions to the new cabinet terminals.
Adapt drives or feedback devices only after signal-level compatibility is checked.
Connect CypCut, height control and process outputs through documented interlocks.

Commissioning and production acceptance

Commissioning progresses from dry axis tests to controlled laser enable and cut trials. Acceptance confirms that motion, safety and process functions repeat correctly on the customer parts selected for the handover.

Prove homing, travel limits, following error response and safe reset sequence.
Validate height control, gas timing, laser enable and alarm handling.
Cut agreed samples and record cycle time, dimensions and operator approval.

Typical Customer Challenges

01

An aging TRUMPF control can restrict spare-part access, diagnostics and process updates.

02

Rising maintenance cost and unpredictable downtime

03

Need for higher power, easier operation or current process functions

Retrofit Engineering

Compatibility comes before configuration

Every project requires a machine-specific assessment. Final hardware, software and achievable performance depend on the existing mechanical accuracy, drive system, I/O, electrical cabinet, safety circuit and selected laser power.

A thorough engineering review confirms the retrofit solution is compatible, integrated correctly and sized around the real machine condition and production target.

Mechanical & electrical condition: Machine base, cabinet condition and safety readiness
Control, drives & fieldbus: Existing controller, drives, I/O and motion network
Target materials & laser power: Material, thickness, process target and proposed power

Assessment outcome

The review turns machine evidence into a clear engineering decision.

Retrofit Engineering

Selecting the right Bochu control platform

CypCut is a leading Chinese sheet-metal laser cutting software platform. Depending on power, motion architecture and process requirements, a project may use CypCut, CypCutPro or an EtherCAT-based FSCUT8000/HypCut solution.

Match the control platform to the installed laser power, motion architecture, I/O scope and the process control your production requires.

Installed power: Laser source and planned duty cycle
Motion & fieldbus: Existing drives, pulse control or EtherCAT readiness
Required process control: Everyday production, advanced functions or high-power coordination

Engineering fit check

Share your machine model, installed controller and production target. We review the practical control path before any retrofit scope is confirmed.
