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” (see
below).
1. Remove the I/O Control Cassette &
cover as described on page 1-16
.
2. Locate & remove Jumper J10 on the
Main Control Board (see diagram).
3. Re-assemble cassette.
4. Wire Enable to “Digital In 6” (see
Figure 1.8
).
5. Verify that [Digital In6 Sel],
parameter 366 is set to “1, Enable.”
