Faults when running multiple drives
The example below demonstrates how to read the LED display on the front cover of the drive to determine the cause of a fault and the corrective
action to take when multiple drives are running from the same network. The example assumes that SW, M/S, and PRM on the master device are all
off, indicated that the master device is operating normally.

Because L.RUN after Station 2 is off, either the comm. line
between Station 1 and Station 2 is disconnected, or the
terminal block has come loose.
Make sure components are connected correctly, using the
LEDs as a guide to indicate a proper connection.

Also make sure that all power cables are properly separated
from comm lines (at least 100 mm away).
