Error name Description Cause
The power supply voltage is low.
There was an instantaneous control
power failure of 30ms or longer.
Shortage of power supply capacity
caused the power supply voltage to
drop at start, etc. .
Power was restored after the bus
voltage had dropped to 200VDC.
(Main circuit power switched on
within 5s after it had switched off.)
Faulty parts in the base unit.
Faulty parts in interface unit.
