Motor Output
Figure 2.2 shows the motor connector on the SD17063. Two phase hybrid
motors with four, six, or eight leads can be wired to the SD17063. Wiring
diagrams are given in the INSTALLING THE SD17063 REV B. chapter,
starting on page 38.
Internally, each motor phase is driven by a bipolar MOSFET H-bridge. The
170Vdc bus used by the H-bridges is derived from the 120Vac input power.
When the motor is powered, 170 Vdc is on the
motor connector pins. To reduce the risk of electri-
cal shock, always install the factory supplied rubber
boot on the motor connector.
Interlock Terminals
The two
INTERLOCK
terminals are a safety feature. The SD17063 will not
power the motor outputs unless these two terminals are connected by a
short wire. If these terminals are not connected, the Motor Fault LED is on,
and the Fault Output is active.
Center Tap Terminals
The two center tap pins,
A CTAP
and
B CTAP
, are for wiring convenience only. They are electrically isolated
from the rest of the drive and are not used to power the motor.
