5-32 Wiring the SLC Servo Module
Connecting the Velocity
Command Use 18 through 22 gauge shielded/twisted pair wire to connect the
analog velocity command output signal (consisting of Drive and DR
Ret connections) from the termination panel Drive connector to the
corresponding terminals of the various servo drives as shown in
Figure 5.15 through Figure 5.23. Connect this signal so that the
resulting direction of motion matches the correct direction of motion
as you defined it.
If you reverse these connections, you reverse the direction the axis
moves in response to a given polarity of the velocity command.
ATTENTION
!
To avoid shorts in the Velocity command circuitry,
do not reverse the Drive Out connections of the SLC
Servo Module. The drive amplifiers of some vendors
only provide a single-ended input for the Velocity
command.
