BUS Module
The SERVOSTAR family includes a variety of BUS Modules that convert a
single-phase logic voltage and a three-phase AC line into the drive’s DC logic
power and main DC BUS.
Features
• Converts single or three-phase AC main lines into a rectified DC BUS
(check BUS Module Electrical Specifications table to verify specific BUS
Module operation). The input consists of a 3φ diode bridge and BUS
capacitors. These capacitors help to minimize BUS ripple, and therefore,
BUS drooping during the peak power demands of the load.
• All units have soft-start capability to minimize the effect of “in-rush”
current spikes inherent in a power-
up cycle. This feature eliminates the need
for a costly isolation transformer.
• The logic BUS Module on all units consists of a SMPS to develop the
required ±15 V and +8 V from either the main line (use L
A
and L
B
) or a
separate AC logic input. Most BUS Modules can source up to four standard
drives (SRxx200 or SExx200). See AppNote ASU000H on the PSP CD-
ROM for details on logic sourcing.

1
Indicates when voltage is on the caps.
2
Indicates unit is operating in regen and may flash during aggressive accelerations.
3
Indicates unit is still in SoftStart. This LED is also used to indicate when an
OverVoltage fault has occurred from too much power being pumped back into the
system during regen.
4
The relay is a normally-open contact and closes after the unit is powered-up and out
of SoftStart. The contact opens if there is an improper BUS Module voltage (dropping
in and out of SoftStart), an over-heated internal regen resistor, or the main heatsink
becomes too hot.
