The supplied Litco inventory data contains this family. It does not mean a specific unit is on the ready-to-go rack today. Send the complete suffix so Litco can verify the exact unit, condition and current availability.
What to match
Confirm the current class, DC-bus or mains voltage, cooling arrangement and compatible supply architecture.
SERCOS, analog, fieldbus, feedback and option modules must match the machine controls and connected motor.
Record the firmware type, function ID, installed modules and parameters before removing a drive from the machine.
Start with the type code, nameplate photos and machine context. Litco will route the request to the right next step.
