Homing not completed



During the execution

of an operation com-

mand, the next opera-

tion command starts.

The motor shaft drags.

The motor does not

run.

Set SV.Pr02 (Control mode) again.



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.

Parameter



Wiring



Others

The setting of the control mode in the console or the

monitor mode

of “PANATERM

” may be wrong.

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.
