Troubleshooting
5-3-3 Troubleshooting by Means of Operating Status
The Servomotor
does not start.
The Servomotor
operates momen-
tarily but then
stops.
Servomotor rota-
tion is unstable.
Servomotor
rotates without any
commands.
Symptom
The control power supply
is not ON.
The main circuit power
supply is not ON.
The I/O (CN1) wiring is
faulty or disconnected.
The Servomotor or
encoder wiring is
detached.
There is an overload.
Speed and position com-
mands are not being input.
The input signal selections
(Pn50A to Pn50D) are set
incorrectly.
The type of encoder being
used is different from the
parameter setting.
The Servo-ON (SV-ON)
command is not being
sent.
The sensor ON
(SENS_ON) command is
not being sent.
The forward drive prohibit
(POT) and reverse drive
prohibit (NOT) input sig-
nals are remaining OFF.
