SINAMICS G130/G150
1596 List Manual (LH2), 07/2016, A5E03263479A
F07807 Drive: Short-circuit/ground fault detected
Message value: %1
Message class: Ground fault / inter-phase short-circuit detected (7)
Drive object: VECTOR_G
Component: Motor Propagation: GLOBAL
Reaction: OFF2 (NONE)
Acknowledge: IMMEDIATELY
Cause: A phase-phase short-circuit or ground fault was detected at the motor-side output terminals of the converter.
Fault value (r0949, interpret decimal):
1: Short-circuit, phase UV.
2: Short-circuit, phase UW.
3: Short-circuit, phase VW.
4: Ground fault with overcurrent.
1yxxx: Ground fault with current in phase U detected (y = pulse number, xxxx = component of the current in phase V
in per mille).
2yxxx: Ground fault with current in phase V detected (y = pulse number, xxxx = component of the current in phase U
in per mille).
Note:
Also when interchanging the line and motor cables is identified as a motor-side short circuit.
The ground fault test only functions when the motor is stationary.
Connecting to a motor that is either not de-energized or partially de-energized is possibly detected as ground fault.
Remedy: - check the motor-side converter connection for a phase-phase short-circuit.
- rule-out interchanged line and motor cables.
- check for a ground fault.
For a ground fault the following applies:
- do not enable the pulses when connecting to a rotating motor without the "Flying restart" function activated (p1200).
- increase the de-energization time (p0347).
- increase pulse suppression delay time (p1228) to ensure standstill.
- if required, deactivate the monitoring (p1901).
F07808 (A) HF Damping Module: damping not ready
Message value: New message: %1
Message class: Power electronics faulted (5)
Drive object: VECTOR_G
Component: None Propagation: GLOBAL
Reaction: OFF2 (NONE, OFF1, OFF3)
Acknowledge: IMMEDIATELY
Cause: When switching on or in the switched-on state, the HF Damping Module does not return a ready signal.
Remedy: - check the DRIVE-CLiQ wiring to the HF Damping Module.
- check the 24 V supply voltage.
- if required, replace the HF Damping Module.
