The servo motor does not
operate.
The setting of the torque limit
is incorrect.
Check if the torque limit is
"0".
[A]: [Pr. PA11] and [Pr.
PA12], or analog input
[B] [WB] [RJ010]: Setting on
controller side
[GF]: [Pr. PA11], [Pr. PA12],
or setting on controller side
Set it correctly.

Machine is interfering with
the motor.
Check if machine is
interfering.
Remove the interference.
For a servo motor with an
electromagnetic brake, the
brake has not released.
Check the power supply of
the electromagnetic brake.
Turn on the electromagnetic
brake power.
LSP (Forward rotation stroke
end) and LSN (Reverse
rotation stroke end) are not
on.
Check if [AL. 99] is occurring. Turn on LSP and LSN.
[A]
[GF]
SON (Servo-on) is not on.
Check the SON (Servo-on)
state.
Turn on SON (Servo-on).
RES (Reset) is on.
Check the RES (Reset)
state.
Turn off RES (Reset).
[A]
The setting of the control
mode is incorrect.
Check the [Pr. PA01] setting. Set it correctly.
The command pulse is not
inputted in the position
control mode.
Check if the pulse train is
outputted on the controller
side.
Review the setting on the
controller side.
The wiring of the command
pulse train signal is incorrect
in the position control mode.
Check the cumulative
command pulses using the
status display or MR
Configurator2. Input the
pulse train command and
check if the display changes.
Review the wiring. When the
signal is used in open-
collector type, input 24 V DC
to OPC.
The setting of the command
pulse input form is incorrect in
the position control mode.
Check that the pulse train
form outputted with the
controller and the setting of
[Pr. PA13] are matched.
Review the [Pr. PA13]
setting.
Both of ST1 (Forward
rotation start) and ST2
(Reverse rotation start) are
on or off in the speed control
mode or the positioning
mode.
Check the status of ST1
(Forward rotation start) and
ST2 (Reverse rotation start).
Turn on ST1 (Forward
rotation start) or ST2
(Reverse rotation start).
Both of RS1 (Forward
rotation selection) and RS2
(Reverse rotation selection)
are on or off in the torque
control mode.
Check the status of RS1
(Forward rotation selection)
and RS2 (Reverse rotation
selection).
Turn on RS1 (Forward
rotation selection) or RS2
(Reverse rotation selection).
The value selected in the
speed control mode or the
torque control mode is low.
Check SP1 (Speed selection
1), SP2 (Speed selection 2),
and SP3 (Speed selection 3),
and then check if the
selected internal speed is
correct.
Review the selections of SP1
(Speed selection 1), SP2
(Speed selection 2), SP3
(Speed selection 3), and
setting of internal speed.
The value selected in the
positioning mode (point table
method) with BCD input is
low.
Check SPD1 (Speed
selection 1), SPD2 (Speed
selection 2), SPD3 (Speed
selection 3) and SPD4
(Speed selection 4), and
then check if the selected
internal speed is correct.
Review the wiring. Review
the selections of SPD1
(Speed selection 1), SPD2
(Speed selection 2), SPD3
(Speed selection 3), SPD4
(Speed selection 4), and
setting of internal speed.
An analog signal is not
inputted correctly.
Check the values of analog
speed command and analog
torque command using
status display or MR
Configurator2.
Input the analog signals
correctly.
