c. The Drive-Up contact within the BDS4
will open due to Bus undervolts.
4. Only the Control AC line input voltage is
removed.
a. The Drive-Up contact in the BDS4 will
open. The BDS4 is immediately
disabled.
b. Operation of the soft-start/dynamic bus
discharge and other circuits within the
PSR4/5 will not be affected.
c. The PSR4/5 fault contact will open.
1.4.6 Without Soft-Start Circuit or
Dynamic Bus Discharge (Optional)
1. Only the Control AC line input voltage is
applied.
a. The logic bus comes up.
b. A power-up reset pulse is generated in
the BDS4.
c. If no faults (other than main bus
undervolts) are present after the power-
up reset pulse is generated (a delay of
one second) then the drive is ready to be
enabled. However, there can be no
motor movement until the main AC line
input voltage is applied.
2. The Main AC line input voltage is applied.
a. The soft-start circuit charges the Main
DC bus capacitors in the PSR4/5
through a current limiting resistor.

b. The shunt regulator regeneration
circuitry is switched from dynamic bus
discharge to regular mode.
c. The undervoltage fault in the BDS4 is
now cleared (after approximately 3/4
sec. delay), and if jumper J21 is
installed on the BDS4-COMP Board,
the Drive Ready LED will become
illuminated and the Drive-Up contact in
the BDS4 (between Pins 10 and 20 of
Connector C1) will close. The BDS4 is
ready to be enabled and will enable
once the enable input is activated.
3. Only the Main AC line input voltage is removed.
a. The DC bus will bleed down slowly
after approximately five minutes.
b. The shunt regulator is deactivated.
c. The Drive-Up contact within the BDS4
will open.
4. Only the Control AC line input voltage is
removed.
a. The BDS4 will be immediately
disabled.
b. The BDS4 Drive-Up contact will open.
c. The PSR4/5 fault contact will open.
