Motor Does Not Run
Classification
Parameter
Error in control mode

Error in torque limit
setting
Error in operation
parameter setting
Setting out of a
maximum travel range
of target position
Error in a parameter
used by a manufacturer.
Wiring
Main power supply
(L1, L2 and/or L3) of
CN X1 and/or control
power supply (L1C
and/or L2C) does not
turn on. Otherwise, a
voltage value is wrong.
Servo-on input (SRV-
ON) of CN X5 is
opened.
CW/CCW over-travel
inhibit input (CWL/
CCWL) of CN X5 is in
the ON state.
Strobe input (STB) of
CN X5 is opened.
Emergency stop input
(EMG-STP) of CN X5
is opened.
Error in the point
specifying input (P1IN
to P32IN) of CN X5.
Error in input timing of
the strobe input (STB)
and the point specify-
ing input (P1IN to
P32IN) of CN X5.
A stop instruction is
input by the multi
function input 1/2 (EX-
IN1/EX-IN2) of CN X5.
Homing not completed
Others
During the execution
of an operation com-
mand, the next opera-
tion command starts.
The motor shaft drags.
The motor does not
run.

Motor Stops During an Operation
Causes
The setting of the control mode in the console or the
monitor mode of "PANATERM
The torque limit may be smaller than correct torque
necessary for an operation.
A parameter necessary for an operation may not be set.
(If any parameter is not set, the error code No. 68 or 69
is shown.)
An operation command may exceed the maximum
travel range in a positive direction and/or negative
direction.
The setting of parameter used by a manufacturer may
be changed from a default setting.
Voltage of the main power supply and/or control power
supply may not be correct.
The error code No. 11, 12 and/or 13 may occur.
The 7-segment LED on the front panel may show [--].
The servo-on signal may be in the [--] state in the
monitor mode of the console or "PANATERM
The CW/CCW over-travel inhibit input (CWL/CCWL) of
CN X5 may be in the ON state. ("Enable/disable" and
logic are set by SV.Pr53/54.)
The CW/CCW over-travel inhibit input may be in the [--]
state in the monitor mode of the console or "PANATERM
The strobe input (STB) of CN X5 may remain opened.
The strobe input signal may be in the [--] state in the
monitor mode of the console or "PANATERM
The emergency stop input (EMG-STP) of CN X5 may
be opened. (The error code No. 39 is shown.)
The point specifying input (P1IN to P32IN) of CN X5 may
not be input correctly. (Logic can be set by SV.Pr58.)
The state of P1IN to P32IN may not be displayed
correctly in the monitor mode of the console or
"PANATERM ® ".
Waiting time from the input of the point specifying input
(P1IN to P32IN) of CN X5 to the input of the strobe input
(STB) of CN X5 may not be 10 ms or more. (If the
waiting time is less than 10 ms, a target point may be
unstable.)
The deceleration-and-stop, emergency stop and tempo-
rary stop, which are assigned to the multi function input
1/2 (EX-IN1/EX-IN2) of CN X5, may turn on.
(Function selection and logic can be set by SV.Pr5A/5C
and SV.Pr59/5B, respectively.)
Homing may not be completed.
The point output may be "0" in the monitor mode of the
console or "PANATERM ".
®
During the execution of an operation command (a
transistor of the motor operation state output BUSY of
CN X5 turns OFF), you may start the next operation
command.
The motor shaft drags. The motor does not run.
1)After turning the power supply off and separating it
from the machine, the motor shaft may not be rotated
manually.
2)For the motor equipped with electromagnetic brake,
the motor shaft may not be rotated manually if DC 24
V is applied to the brake.
Set SV.Pr02 (Control mode) again.
" may be wrong.
®
Check the setting of SV.Pr5E (1st torque
limit) and SV.Pr5F (2nd torque limit).
Check the parameters of travel, speed
acceleration/deceleration time necessary
for homing operation or step operation in
16.Pr.
Check the set value of 32.Pr01/02.
Initialize all the parameters once and set
them again.
Check the wiring and voltage of the main
power supply (L1, L2 and/or L3) of CN
X1 and/or the control power supply (L1C
and/or L2C).
Check and wire the input signal so that
the SRV-ON input can be connected to
® ". COM–.
Check the wiring of CW/CCW over-travel
inhibit input and check the set value in
SV.Pr53/54.
® ".
Check and wire the input signal so that
the strobe input can be connected to
". COM–.
®
Check and wire the input signal so that
EMG-STP can be connected to COM–.
Check the wiring of P1IN to P32IN.
Insert waiting time of 10 ms or more.
Check the setting and wiring of the multi
function input 1/2.
Complete the homing.
Refer to page 114.
Check that the transistor of the motor
operation state output turns ON and then
start the next operation command.
If the motor shaft cannot be rotated, ask
the local shop to repair the motor.
