Third Party Controls
For conversion to third party control of the VFD, perform the
following procedure:

X1-13 (control of VFD start/stop).
2. Remove the factory-installed jumper between X1-10 and
X1-16, and replace with a normally closed safety contact
for control of VFD start enable.
3. Install speed signal wires to AI-1 and AGND. This input is
set at the factory for a 4 to 20 mA signal. If a 0 to 10 vdc
signal is required, change DIP switch J1 (located above
the VFD control terminal strip) to OFF (right position to
left position) and change parameter 1301 to 0% from 20%.
VFD Diagnostics
The drive detects error situations and reports them using:
• the green and red LEDs on the body of the drive (located
under the keypad)
• the status LED on the control panel
• the control panel display
• the Fault Word and Alarm Word parameter bits (parame-
ters 0305 to 0309)
The form of the display depends on the severity of the error.
The user can specify the severity for many errors by directing
the drive to ignore the error situation, report the situation as an
alarm, or report the situation as a fault.
FAULTS (RED LED LIT)
The VFD signals that it has detected a severe error or fault by:
• enabling the red LED on the drive (LED is either steady or
flashing)
• setting an appropriate bit in a Fault Word parameter (0305
to 0307)
• overriding the control panel display with the display of a
fault code
• stopping the motor (if it was on)
