Termination resistors without inductors as shown in Figure 9 can only be used for baud rates below 1.5 Mbps.
Baud rates 1.5 Mbps and higher require termination with resistors and inductors as shown in Figure 7 .

7. Route the option wiring.
Depending on the drive model, some drives may require routing the wiring through the side of the front cover to
the outside. In these cases, use diagonal cutters to cut out the perforated openings in the left side of the drive
front cover as shown in
Figure 10 -A and leave no sharp edges to damage wiring.
Route the wiring inside the enclosure as shown in Figure 10 -B for drives that do not require routing through the
front cover. Refer to the Peripheral Devices & Options section of the drive Technical Manual for more
information.

8. After connecting the prepared cable for the 9-pin D-sub communication connector CN5, recheck the option wire
routing performed in step 6.
A – Route wires through the openings
provided on the left side of the front
cover.
