Motor Wiring; Control Signal Wiring; Active High Definition; Active Low Definition - Baldor DBSC105-AAA-1 Installation And Operating Manual

Section
Connect the motor leads as follows:
1. Connect motor phase U to X1-U.
2. Connect motor phase V to X1-V.
3. Connect motor phase W to X1-W.
All wiring from external devices to the control are made at the connectors
shown in Figure 3-1.
The inputs at X3 pins 7, 9, 10, 11 and 12 can be wired for active high or active
low conditions. Pin 7 is the CREF (Control Input Reference) point.

Active High Definition

If the Control Inputs are to be wired as Active High, CREF is connected to
GND. When a control input is at +24VDC (range +12VDC to +29VDC), it is
active and when it is at GND it is inactive. Figure 3-2 shows this relationship.

Active Low Definition

If the Control Inputs are to be wired as Active Low, CREF is connected to
+24VDC (range +12VDC to +29VDC). When a control input is at GND, it is
active and when it is at +24VDC it is inactive. Figure 3-2 shows this
relationship.
