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.
