CHAPTER 3 - INSTALLATION AND CONNECTION
NOTES!
For the proper operation of configuration 2, terminal 5 shall
be connected to terminal 1 (general enable).
The frequency reference can be sent via AI1 analog input
(as shown in figure 3.16), 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 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 - Wire ON/OFF
Function enabling (three wire control):
Set DI1 to ON: P263 = 14
Set DI2 to OFF: 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.
The figure 3.17 below shows the connections at VFD terminals
for this type of configuration.
S1: Start
S2: Stop
S3: Changes the
speed direction
