700002 Sinamics power supply WARNING!
Cause:
The SINAMICS NC servo axis drives system reported a fault and therefore could not set the drive
ready signal.
Remedy:
Check input supply connections to the power supply module.
Check all terminal block connections to the power supply and NCU module are full inserted.
Refer to Siemens SINAMICS troubleshooting manual on DocOnCD or via the Siemens online
documentation service DocOnWeb.
700004 Spindle drive not enabled
Cause:
The main spindle fails to start following the user request because the spindle enable signal via the
NCK > PLC interface is reporting that the spindle drive module has a fault.
Remedy:
Check spindle drive module LED indicator is RED.
Replace the spindle drive module.
Refer to Siemens SINAMICS troubleshooting manual on DocOnCD or via the Siemens online
documentation service DocOnWeb.
700006 Electrical cabinet temperature is too high!
Cause:
The bi-metallic thermal switch located inside the electrical control cabinet has exceeded 45°C
because the electrical cabinet (ECC) cooling system has stopped functioning.
NC program execution is not permitted when this alarm is active.
Remedy:
Shut-off electrical power to the machine from the mains isolator and open the electrical cabinet
door to let it cool down. Check that the cooling system circuit breaker has not tripped.
After 45 minutes close the cabinet door and then switch power back on. Check that the cooling
system operates as normal.
If the alarm re-appears immediately, then the bi-metallic thermal switch has not reset itself.
Remove the switch from the ECC and put it into a refrigerator for 20minutes to get it back to the
reset state. Re-fit the switch inside the ECC and check that the alarm clears.
