3 Wire Start/Stop (Remote Mode):
Parameters:
1.
Set DI1 to GENERAL ENABLE (P263=2).
2.
Set DI3 to START (P265=14). See note below.
3.
Set DI4 to STOP (P266=14).
4.
Set P224=1 (DIx) if you want the 3 wire control
in local mode.
5.
Set P227=1 (DIx) if you want the 3 wire control
in remote mode.
Control Wiring: Verify there is a jumper between XC1-8
and XC1-10 or inverter will not work. “Start” and “Stop”
are momentary push button switches and are connected
as shown in Figure 4. “Start” is a N.O. (normally open)
contact and “Stop” is a N.C. (normally closed) contact.
Note: When initially setting DI3 to START (P265=14) an
E24 (programming) error will occur and the display will
flash until DI4 is set to STOP (P266=14).

Operation from Remote Analog Input (Speed Pot):
Parameters:
1.
P222=1 (Remote Speed Ref=AI1)
2.
P235=0 (Analog Input Signal =0-10Vdc)
Control Wiring: Connect jumper between XC1-13 and XC1-14 or Speed
Pot will not work. Speed Pot value must be
≥ 5KΩ but ≤ 10KΩ at 2W and
is connected as shown in Figure 5.
Dip Switch Settings: Analog Input 1 (AI1) is set at 0-10Vdc (default) by
the S1-2 Dip Switch on the control board (S1-2=OFF). To detect 4-20mA,
set S1-2=ON and set P235=1. Note: S1-1 is for Analog Input 2. See the
CFW09 User’s Guide for full explanation of analog inputs.

Fault Codes:
When a fault is detected, the inverter is disabled and the Fault Code is displayed. (Example E01). To restart the inverter
after a fault has occurred, the inverter must be reset. Resetting the inverter can be done by disconnecting and reapplying
AC power (power-on reset), by pressing the “O/RESET” key (manual reset), automatic reset, or via digital inputs. For
details on Reset and a full list and description of Fault Codes please read Chapter 7 in the CFW09 User’s Guide.
