1.12 Charging the internal DC link capacitors
After extended
storage times or
extended downtimes during which no
power is supplied (> 12 months), the capacitors in the internal DC link must
be recharged in a controlled manner in order to prevent damage. To do this,
the DA1 variable frequency drive must be supplied with power, with a
controlled DC power supply unit, via two mains connection terminals
(e.g. L1 and L2).
In order to prevent the capacitors from having excessively high leakage
currents, the inrush current should be limited to approximately 300 to 800
mA (depending on the relevant rating). The variable frequency drive must not
be enabled during this time (i.e. no start signal). After this, the DC voltage
must be set to the magnitudes for the corresponding DC link voltage
(U
DC
1.41 x U
e
) and applied for one hour at least (regeneration time).
• DA1-12…, DA1-32…: about 324 V DC at U
e
= 230 V AC
• DA1-34…: about 560 V DC at U
e
= 400 V AC
• DA1-35…: about 705 V DC at U
e
= 500 V AC
