Capacitors
The drive intermediate DC circuit employs several electrolytic capacitors. Their
lifespan depends on the operating time of the drive, loading and ambient
temperature. Capacitor life can be prolonged by lowering the ambient temperature.
In frames R1 to R3, the capacitors are integrated to the ZINT board and in frames R4
to R5 to the ZMAC board. In frames R6 to R8, the capacitors are separate.
