4.5 Terminals Found on the RSi S4 Control Board
4.5.1 Description of the Control Terminals
Figure below shows the control terminals found on the I/O board of the S4 AC drive. 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.
See page 13 for specication information concerning these features.
