8.2.4 Effects of the different charging circuits
Following incompatibilities result because of charging and must be checked by the user
operating devices with the new current-controlled charging-method.
m Charging time: Adapt timeout values in master-control to avoid possible error messag-
es because of not in time ready-to-operate signal.
m Ensure clockwise-rotating-field. The device does not identify the direction of the rotat-
ing field. 
In case of a counter-clockwise-rotating-field no charging is done, after 20 s the attempt
of charging is stopped and error 089 (power unit not ready-to-operate) is generated.

In rare cases a counterclockwise rotating field can cause an abrupt charging and a
tripped fuse.

For error correction two power supply phases must be exchanged, e. g. the cables
connected to 1U1 and 1V1. The error is corrected, assumed there is no other error.
The advantages of the current-controlled charging are (in short):
m The maximum chargeable DC link capacitance is higher than without the current-con-
trolled charging.
m The dependency of the DC link capacitance on the charging current is reduced. The
self-protection level of the device against incorrect dimensioning is improved.
