Configurable LCL Filter Capacitor Failure Response
Review the following Attention statement if you intend to configure the Line Side Converter to produce an alarm instead of a fault when the LCL Capacitor Failure event occurs.
ATTENTION:
Risk of equipment damage exists.
You must read the following information before you can enable the Line Side Converter to produce an alarm instead of a fault when the LCL Filter Capacitor Failure event occurs.
Operating the drive product during the LCL Capacitor Failure event may damage the LCL filter. This damage may lead to catastrophic product failure and collateral damages.
It is your responsibility to configure drive parameters, understand the causes and consequences of LCL capacitor failure, and meet safety requirements in accordance with all applicable codes and standards. If enabling the Line Side Converter to produce an alarm instead of a fault when the LCL Capacitor Failure event occurs is desired, you must certify the safety of the application. To acknowledge that you have read this ‘Attention’ and properly certified the application, set bit 6 ‘CapFailAlrm’ of parameter 13:40 [Conv Options Cfg]. This action removes Fault 24, ‘CapFailureCfg’. It allows parameter 0:452 [LCLCapFailActn] to be set to 0 ‘Alarm’, enabling an alarm instead of a fault.
