Documentation from the manufacturer
Faults and fixes 6FC5370-0AA00-2BA1
Problems with 6FC5370-0AA00-2BA1: alarm 2100 or 2101, NCK battery
Alarm 2100 is the warning that the NCU buffer battery is nearly flat, 2101 the message that it is flat. Replace the battery with the control switched on, otherwise machine data, programs and the axis references are lost. Make a complete series start-up backup (NC, PLC, HMI) first.
6FC5370-0AA00-2BA1: operator panel dark, keys unresponsive or alarm 300xxx
A dark OP panel with the control running is usually the backlight or the panel's power supply; keys that do not respond are a worn membrane or a loose connection to the MCP/TCU. Alarms in the 300xxx range come from the drives (611D) and name the axis; look for those at the drive module, not at the panel.
What do I check when replacing a 6FC5370-0AA00-2BA1?
On SINUMERIK components the software version (NCK, HMI, MCP firmware) must match the machine; the version is shown in the diagnostics or on the rating plate. Restore the series start-up backup on a replacement NCU and check the licence (hardware-bound on 840D sl). Panels and MCPs with the same issue are interchangeable without further steps.
Fault not fixed: replace, exchange or repair the 6FC5370-0AA00-2BA1?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the 6FC5370-0AA00-2BA1 refurbished: tested to this family's test protocol, with a test report per serial number, with a 24-month warranty. The current lead time is shown with the condition on this page. Prefer an exchange: you get a refurbished unit straight away and return the faulty one within 14 days. Repairing your own unit is also possible: diagnosis, then a fixed price.
What information should I send for a quick diagnosis?
A photo of the rating plate (order number, product version, firmware), the exact fault code or LED state, when the fault occurs (at power-up, on enable, under load) and what you have already tried. For PLCs an export of the diagnostic buffer, for drives the parameter set. With that we can usually say the same day whether replacing, exchanging or repairing is best.
