Baldor FPX A05T - X1 +24 VDC Logic Supply; X3 Control Inputs & Digital I;O Connections

3-12 Receiving & Installation
MN1276
X1 +24VDC Logic Supply For FPxAxxxx-xxx3 only. A separate 24VDC supply to the “Logic
Power” input is required for operation. An external 24 VDC power source must be
used. If bus power is lost, the logic circuits are still active if the 24VDC is present.
This is important to maintain position reference, for example. If the control was
not ordered with this option, do not connect any voltage to these pins.
X3 Control Inputs & Digital I/O Connections
Control Inputs X3 pins 1 and 2 allows connection of an external analog command input. This
input can accept a 0-10VDC or "10VDC signal and can be wired as a single
ended or differential input, shown in Figure 3-15.

X3 Digital Inputs - Opto Isolated Inputs (uses CREF, X3-7)
Active High (Sourcing) - If pin X3-7 is grounded, an input is active when it is
at +24VDC (+12VDC to +30VDC).
Active Low (Sinking) - If pin X3-7 is at +24VDC (+12VDC to +30VDC), an
input is active when it is grounded.
Logic input connections are made at terminal strip X3. Input connections can be
wired as active High or active Low as shown in Figure 3-16. X3 pin 7 is the
Control Reference point (CREF) for the Opto Isolated Input signals.
Note: An internal 24VDC power supply connection is not available from the control
to power the Opto Input circuits. A customer provided external power
source must be used as indicated in Figure 3-16.
