Connecting the embedded fieldbus
Embedded fieldbus can be connected to the drive with EIA-485 or RS-232.
 Connection diagram
EIA-485
The figure below shows the fieldbus connection.
Terminate the EIA-485 bus with a 120 ohm resistor at the end of the network by
setting the jumper J701 shunts as in the figure below.
RS-232
Plug a communication cable into the control panel connection X2. The cable must be
shorter than 3 meters.
