Status and error display

The PDC has LED displays for indicating the current operating state and the diagnostics status.
The "RDY/ERR" LED indicates the status of the drive state. If the LED is off, the drive is ready
for operation. If it is permanently lit green, the drive is running. If the LED flashes red, there is
an operating fault.
The "SAFE" LED indicates the status of the Safety Integrated functions.
The LEDs assume different statuses during startup. The displays of the LEDs operate
independent of one except during firmware update. The figure below shows the various LED
displays on the PDC.
