Encoder Terminal Block (Vector Control Option Only)
Sample Encoder Wiring
Hardware Enable Circuitry (Vector Control Option 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 “dedicated” hardware enable
configuration can be utilized. This is done by removing a jumper and wiring the enable input to “Digital In 6”.
