SINAMICS G120 Control Units CU240S, Edition 05/2007
F00015 Motor temperature signal lost
Reaction: OFF 2 (OFF 3)
Acknowledge: Quit fault eg. via DI2
Cause: Open or short circuit of motor temperature sensor. If signal loss is detected, temperature monitoring switches over
to monitoring with the motor thermal model.
Remedy: Check the following:
• the connection of the motor temperature sensor to the control unit
• the setting of p0601
F00020 Mains Phase Missing
Reaction: OFF 2 (OFF 3)
Acknowledge: Quit fault eg. via DI2
Cause: Fault occurs if one of the three input phases are missed and the pulses are enabled and drive is loaded
Remedy: Check the input wiring of the mains phases
F00021 Earth fault
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: Fault occurs if the sum of the phase currents is higher than 5 % of the nominal inverter current.
Remedy:
Note:
Framesizes D to F: this fault only occurs on inverters that have 3 current sensors.
F00022 Powerstack fault
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: This hardware fault caused by the following events:
• DC-link overcurrent = short circuit of IGBT
• Short circuit of chopper
Remedy: Contact Service Department.
Change inverter power module
F00023 Output phase fault
Reaction: OFF 2 (OFF 3)
Acknowledge: Quit fault eg. via DI2
Cause: One output phase is disconnected.
Remedy: Check motor connection.
F00025 F3E Dclink Ripple
Reaction: OFF 2 (OFF 3)
Acknowledge: Quit fault eg. via DI2
Cause: Large ripples on the dclink.
Remedy: Contact Service Department.
F00026 Supply to Gate Driver Not Enabled
Reaction: OFF 2
Acknowledge: Quit fault eg. via DI2
Cause: Gate driver not enabled. Can be caused also by a synchronization error of the safety state machines.
Remedy: Contact Service Department.
