Problems with 6SL3120-1TE24-5AA3: F30001, F30002 or F30003
On SINAMICS the F30xxx messages are faults of the power unit. F30001 is overcurrent (short circuit or earth fault in motor or cable, too short an acceleration ramp, wrong motor data), F30002 DC-link overvoltage (too short a deceleration ramp without braking resistor, regenerative operation), F30003 undervoltage (mains gone or sagging, precharging failed). If F30001 returns with the motor disconnected, the power unit itself is defective.
6SL3120-1TE24-5AA3: F30004, F30005 or A05000, the drive runs hot
F30004 is heat sink overtemperature, F30005 thermal overload (I²t) of the power unit, A05000 the warning that precedes it. Clean the heat sink and the fan, check the airflow and cabinet temperature and whether the load matches the rating. A fan that no longer reaches speed is the most common cause on older units.
6SL3120-1TE24-5AA3: F30021 earth fault or F07900 motor blocked
F30021 reports an earth fault on the motor side: measure the insulation of motor and motor cable (megger) before suspecting the drive. F07900 means the motor does not turn while torque is demanded: mechanical blockage, brake not released or wrong motor data. Neither fault is often caused by the drive itself.
What do I check when replacing a 6SL3120-1TE24-5AA3?
On SINAMICS G120 the control unit and the Power Module are replaced separately: a power unit fault only needs a new Power Module, the parameters stay on the control unit. Keep the parameter set on the memory card or in STARTER/Startdrive. Mind rating, frame size, voltage and firmware version, and whether a braking resistor or filter comes along.
Fault not fixed: replace, exchange or repair the 6SL3120-1TE24-5AA3?
Replacing from stock is the fastest route when a machine is down. Van Haelen supplies the 6SL3120-1TE24-5AA3 refurbished (tested, with a test report per serial number) or new in factory packaging, 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.
Frequently asked questions
Is the 6SL3120-1TE24-5AA3 still available?
Not new from the manufacturer any more: the 6SL3120-1TE24-5AA3 was discontinued since January 2025. Van Haelen supplies it refurbished and tested.
Does the 6SL3120-1TE24-5AA3 replace the 6SL3120-1TE24-5AA1?
Yes. According to the manufacturer the 6SL3120-1TE24-5AA3 is the successor of the 6SL3120-1TE24-5AA1. Before replacing, check that the project and the connections match the new version; if in doubt we also supply the 6SL3120-1TE24-5AA1 itself, refurbished or new, as long as it can be found.
What does refurbished mean?
Cleaned, inspected, aged or critical components replaced and tested to our test protocol for this product family. You get a 24-month warranty, a test report and a serial number label.
What should I check when replacing a 6SL3120-1TE24-5AA3?
Keep the parameter set of the old unit; it makes setting up the replacement quick. Also check power rating, supply voltage and any option boards.
Can I exchange or repair my faulty unit?
Yes. With an exchange Van Haelen supplies a refurbished unit straight away and you return the faulty one. With a repair you first get a diagnosis and then a fixed price, with test report and warranty.
