Hardware Enable Circuitry (Enhanced Control Only)
By default, the user can program a digital input as an Enable input. The status of this input is interpreted by drive software. If the application requires the drive to be disabled without software interpretation, a hardware enable configuration can be utilized. This is done by removing the enable jumper (ENBL JMP) and wiring the enable input to “Digital In 6” (see below).

  1. Remove drive cover.
  2. Locate and remove the Enable
    Jumper on the Main Control
    Board (see diagram).
  3. Wire Enable to “Digital In 6”
  4. Verify that 366 [Digital In6
    Sel] is set to option 1 “Enable”.
