CHAPTER 3 - INSTALLATION AND CONNECTION
NOTES!
S1 and S2 are push buttons, start (NO contact) and stop
(NC contact), respectively.
The speed reference can be via analog input AI1 (as in
Connection 2), via keypad (HMI-CFW08-P), or via any other
source (as described in the parameters P221 and P222).
When a line fault occurs by using this connection with the
motor running and the S1 and S2 switches are in original
position (S1 openned and S2 closed), at the moment the
voltage returns the inverter will not be enabled automatically,
it will only be enabled if the S1 switch were closed again (a
pulse at the Start digital input).
Connection 4 - FWD/REV Function
Parameter to be programmed:
Set DI1 to Forward Run : P263 = 8
Set DI2 to Reverse Run: P264 = 8
Make sure the inverter commands are via terminals, i.e.,
P229 = 1 to local mode or P230 = 1 to remote mode.
The figure 3.18 below shows the inverter terminal connection
for this type of driving.

NOTE!
For the correct operation of the connection 4, P266 must
be programmed as “Not Used”.
The speed reference can be via analog input AI1 (as in
connection 2), via keypad (HMI-CFW08-P), or via any other
source (refer to the description of parameters P221 and
P222).
When a line fault occurs, this connection with switch S1 or
switch S2 is closed, the motor will be enabled automatically
as soon as the line is re-established.
