8 Service, maintenance and fault rectification Fault rectification 8.3.3.1 Tests without a power supply DANGER Danger due to electric current! If the terminals are not accessible externally, do not open the device because you will be exposed to a great risk and this will invalidate the warranty. ● In this case, contact your local Siemens branch office.
Service, maintenance and fault rectification Fault rectification 8 Static check on the drive The following checks are standard tests. These tests can be performed on most drives which are designed in accordance with the conventional principle "Rectifier – DC bus – IGBT bridge". The DC bus terminals of the PM230/G120P device are not generally used. However, the terminals are accessible on some models. Set the multimeter to "Diode" in order to measure the terminals.
8 Service, maintenance and fault rectification Fault rectification How to proceed if a fault is discovered The variable speed drive has failed one of these tests: Remove the Power Module (power unit) in order to replace or repair it. A short circuit is present at the input rectifiers or at components of the IGBT bridge: Check the state of fuses in the supply line, of contactors, disconnectors or of the motor itself.
Service, maintenance and fault rectification Fault rectification 8.3.3.2 8 Power test DANGER Danger due to electric current and moving parts during commissioning of equipment or plant! Components connected to the variable speed drive might move randomly while the drive is being commissioned. Movements of this kind can cause serious physical injury or death. ● Before commissioning the drive, make the system safe, for example by cordoning it off.
8 Service, maintenance and fault rectification Fault rectification 8.3.3.3 Function test Preliminary test Perform the preliminary tests set out in the table below without the motor connected. Only in this way can you be certain that any faults discovered are attributable to the variable speed drive rather than the connected motor. Check/Test Description MANUAL operation 1. 2. 3. 4. 5. OK Monitor the motor output terminals using a suitable multimeter which is also capable of measuring PWM voltages.
Service, maintenance and fault rectification Fault rectification 8 IOP diagnostics The following procedures are designed to test the wiring. They ensure that the correct signals reach the drive. If this reveals that the control wiring is correct, either the drive is defective or the configuration is incorrect. Check/Test Description IOP diagnostics – digital inputs 1. IOP diagnostics – digital outputs IOP diagnostics – analog inputs IOP diagnostics – analog outputs Siemens Smart Infrastructure 2. 1.
8 Service, maintenance and fault rectification Fault rectification IOP simulation Perform the following checks to test the inputs of the drive. These tests can detect wiring errors and any potential errors in the variable speed drive settings. Check/Test Description IOP I/O simulation 1. 2. OK Select the "Diagnostics / I/O simulation" menu. If the drive output responds to the simulation steps performed, this indicates that the drive is probably working properly but that the wiring is incorrect.
