4.6 Terminals Found on the X4 Control Board
4.6.1 Description of the Control Terminals
Figure 4-3 shows the control terminals found on the I/O board of the X4 AC drive. See page 6 for
specifications. Table 4-7 on page 26 describes the control terminals.
The drive’s control terminals are referenced to earth ground through a resistor / capacitor network.
Use caution when connecting analog signals not referenced to earth ground, especially if the
communications port (J3) is being used. The J3 port includes a common reference that can be
connected to earth ground through the host PLC or computer.
