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 DC1-S… variable frequency drive must be supplied with power, with a
controlled DC power supply unit, via the mains connection terminals (e.g.,
L1/L und L2/N).
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).
•
DC1-S1…: about 162 V DC at U
e
= 115 V AC
•
DC1-S2…: about 324 V DC at U
e
= 230 V AC
