Configurable LCL Filter Capacitor Over Resonance Response
Review the Attention statement that follows if you intend to configure the line side converter to produce an alarm instead of a fault when the LCL Capacitor Over Resonance 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 Over Resonance event occurs.
Operating the product (drive or bus supply) during the LCL Capacitor Over Resonance 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 over resonance, 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 Over Resonance 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 5 ‘CapORsncAlrm’ of parameter 13:40 [Conv Options Cfg]. This action removes Fault 56, ‘CapOvrRsncCfg’. It allows parameter 0:453 [CapOvrRsncActn] to be set to 0 ‘Alarm’, enabling an alarm instead of a fault.
