Error name Description Cause
The power supply voltage is low.
There was an instantaneous control
power failure of 40ms 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 15VDC.
(Main circuit power switched on
within 5s after it had switched off.)
2010 10 Under voltage
The power supply voltage dropped to
20VDC or less.
Faulty parts in the servo amplifier.
2011 11 Board error 1 Printed circuit board fault.
2012 12 Memory error 1 ROM or RAM memory error.
2013 13 Clock error Printed circuit board fault.
2015 15 Memory error 2 EEP-ROM error
Faulty parts in the servo amplifier.
The encoder connecter (CNP2) is
disconnected.
Fault in the encoder.
2016 16 Encoder error 1
Communication error occurred
between encoder and servo amplifier.
Encoder cable fault. (Wire breakage
or shot)
2017 17 Board error 2 CPU or parts of the circuit fault. Faulty parts in the servo amplifier.
The encoder connecter (CNP2) is
disconnected.
Fault in the encoder.
2020 20 Encoder error 2
Communication error occurred
between encoder and servo amplifier.
Encoder cable fault. (Wire breakage
or shot)
