8.4.3 MULTI-FUNCTION INPUT TERMINALS
The Multi-Function Input Terminals can be used control the drive for Reset, External Fault, and
Accel/Decel #2. For NPN and PNP Circuits, see Appendix E, on page 70.
8.4.3.1 RESET
It is advisable to connect a momentary normally open contact to Multi-Function Input Terminal
"4". This allows the drive to be restarted after a fault has been cleared. See Figure 30, for
connections and drive programming.
CAUTION! If a maintained Reset Contact is used and kept in the closed position while
the drive is in the Run Mode (Start jumpered or the Start/Stop contact is in the "Start"
position) and a direction is selected, the drive will automatically restart after a fault has
been cleared.
Connect the Reset Contact to Multi-Function Input Terminal "4" (TB1 Terminal "8"), which is
factory set to Reset ("0009"). The common of the contact can be connected to either common
TB1 Terminal "4" or "11".
Operation: When a fault has been cleared, momentarily activate the Reset Contact to reset the
drive.

8.4.3.2 EXTERNAL FAULT
The Multi-Function Input Terminals can be used to "stop" the drive when a fault condition occurs
elsewhere in the equipment. The connection to the Multi-Function Input Terminal can be from a
normally open or normally closed relay contact or PLC. See Figure 31, on page 40, for
connections and drive programming.
WARNING! External Fault is not to be used as an Emergency Stop or safety
disconnect since it is not fail-safe. Use only the AC line for this purpose.
Note: For a normally open contact, program the respective Multi-Function Input Terminal to
"0008". For a normally closed contact, program the respective Multi-Function Input Terminal to
"0012".
