Home (Orient) Switch Input
The Home or Orient function causes the motor shaft to rotate to a predefined home
position. The homing function allows shaft rotation in the drive forward direction only.
The home position is located when a machine mounted switch or the encoder “Index”
pulse is activated (closed). Home is defined by a rising signal edge at terminal J1-27.
The shaft will continue to rotate only in a “Drive Forward” direction for a user defined
offset value. The offset is programmed in the Level 2 Miscellaneous Homing Offset
parameter. The speed at which the motor will “Home” or orient is set with the Level 2
Miscellaneous Homing Speed parameter.
A machine mounted switch may be used to define the Home position in place of the
encoder index channel. A differential line driver output from a solid state switch is
preferred for best noise immunity. Connect this differential output to terminals J1-27 and
J1-28.
A single ended solid-state switch or limit switch should be wired as shown in Figure 3-18.
Regardless of the type of switch used, clean rising and falling edges at J1-27 are required
for accurate positioning.
Note: Control requires dynamic brake hardware for Orient (Homing) function to
work. Control will trip without dynamic brake hardware installed. Size A and B
controls ( “–E” suffix) are shipped with factory installed dynamic brake
hardware.

Buffered Encoder Output
The control provides a buffered encoder output on pins J1-31 to J1-38 as shown in Figure
3-19. This output may be used by external hardware to monitor the encoder signals. It is
recommended that this output only drive one output circuit load.
