2.When two or more inverters are connected

The following example explains the causes and corrective actions for fault which may be judged from the LED status of the CC-Link units (CCL003Z) of the inverters under the condition that the SW, M/S and PRM LEDs of the master unit are off (the master unit setting is proper) in the system configuration shown below:
