INSTALLATION AND CONNECTION
NOTE!
The frequency reference can be sent via AI1 analog input (as
shown in figure above), via keypad HMI-CFW08-P, or via any other
source (as described in Chapter 6 - P221 and P222).
When a line fault occurs by using this type of connection with switch
S3 at position "RUN", the motor will be enabled automatically as soon
as the line is re-established.
Connection 3 - 3 Wire Start/Stop
Function enabling (three wire control):
Set DI1 to Start: P263=14
Set DI2 to Stop: P264=14
Set P229=1 (command via terminals) if you want the 3-wire control in
local mode.
Set P230=1 (command via terminals) if you want the 3-wire control in
remote mode.
FWD / REV Selection:
Program P265=0 (DI3) or P266=0 (DI4), according to the selected digital
input (DI).
≠
If P265 and P266 0, the direction of rotation is always FWD.

NOTE!
S1 and S2 are push buttons, NO and 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 (see Chapter 6 -
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), the inverter will not be enabled automatically as soon
as the line is re-restablished.
The Start/Stop function is described in Chapter 6.
