Description
15 - 76
MELSEC-Q
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.
CNP3 or CNP1B connector
unplugged.
Faulty parts in interface unit.
Faulty parts in the drive unit.
The encoder connecter is
disconnected.
Fault in the encoder.
Encoder cable fault. (Wire breakage
or shot)
Faulty parts in the interface unit or
drive unit.
Wrong combination of drive unit
and servomotor connected.
IFU parameter " Pr.111 " to
" Pr.118 " setting mistake.
