For frame size 07 drives and larger, which use a d.c. link charge system based on a half controlled thyristor input bridge, the rate at which the d.c. bus
is charged can be reduced by setting
Slow Rectifier Charge Rate Enable
(
O17
) to one. This will reduce the charging current which may be required if
significant additional capacitance is added to the d.c. link to prevent rupturing of input fuses.
