Appendix 1 Error Codes
192DH Rapid stop signal ON • "[Rq.1141] Rapid stop command" is ON when starting.
• "[Rq.1141] Rapid stop command" is ON at the timing of
home position return.
• "[Rq.342] Command generation axis rapid stop
command" is ON when starting.
• Turn OFF the "[Rq.1141] Rapid stop command" and
then start it.
• "[Rq.1141] Rapid stop command" and then perform the
home position return.
• Turn OFF the "[Rq.342] Command generation axis
rapid stop command" and then start it.
192EH PLC ready ON during
deceleration
"[Rq.1120] PLC ready flag" turned from OFF to ON again
during deceleration.
When all axes stopped, turn "[Rq.1120] PLC ready flag"
ON.
192FH Servo error detection
signal ON during
controlling
"[St.1068] Servo error detection" is ON when controlling. Start after disposal at the servo error.
1940H Start at home position Start scale home position signal detection method home
position return when "[St.1070] Home position return
complete" and "[St.1074] External signals DOG/
CHANGE" is ON.
Perform the home position return after moving to the
proximity dog ON by the JOG operation, etc.
194BH Driver home position
return method error
Operation error occurred in driver when executing driver
home position return to stepping driver.
Check the operation alarm details and then execute home
position return again.
194CH Time out for awaiting
home position return mode
Cannot acquire normal data from stepping driver during
home position return.
Execute home position again. If the same error happens,
hardware of Motion controller and stepping may be error.
Explain the error symptom and get advice from our sales
representative.
194DH Time out for awaiting
operation ON
Cannot acquire normal data from stepping driver during
home position return.
Execute home position again. If the same error happens,
hardware of Motion controller and stepping may be error.
Explain the error symptom and get advice from our sales
representative.
194EH Time out for awaiting
operation completed ON
Cannot acquire normal data from stepping driver during
home position return.
Execute home position again. If the same error happens,
hardware of Motion controller and stepping may be error.
Explain the error symptom and get advice from our sales
representative.
1977H Encoder absolute position
data not established
Home position return is started on using direct drive motor
when the absolute position data of the encoder has not
been established.
Turn the power supply of the system or servo amplifier
from OFF to ON after passing the zero point of the motor
by the JOG operation, etc.
1978H Z-phase pass parameter
incorrect
• When using the scale home position signal detection
method home position return or the dogless home
position reference method home position return
(operation A), the servo parameter PC17 is other than
"Pass Z-phase After AC-ON".
• When using the dogless home position reference
method home position return (operation B), the servo
parameter PC17 is other than "Not Pass Z-phase After
AC-ON".
• Set "Pass Z-phase After AC-ON" to the servo
parameter PC17.
• Set "Not Pass Motor Z-phase After AC-ON" to the
servo parameter PC17.
• When changing PC17, once the power supply of servo
amplifier is turned OFF after changing parameter and
then turned ON again.
1979H Home position return
method incorrect error
Home position return is started with the home position
return method which is not supported by the connected
machine.
Change to the home position return method which is
supported by the connected machine.
197AH Home position return zero
not passed
ZCT unset
The "[St.1066] zero pass" turned off at the re-movement at
the home position return for ZCT unset proximity dog
method, count method limit switch combined method, or
start in the home position return for data set method.
Perform the home position return when the "[St.1066]
Zero pass" is ON.
197BH Home position return
complete signal ON
The "[St.1070] Home position return complete" turned on
at the home position return of proximity dog method, dog
cradle method, stopper method or dogless home position
signal reference method.
• For proximity dog method dog cradle method stopper
method: Return to a point before the proximity dog
signal ON by JOG operation or positioning operation
etc. and perform the home position return.
• For dogless home position signal reference method:
Return to a point before the proximity dog signal ON by
JOG operation or positioning operation etc. and perform
the home position return.
19
7CH All axes rapid stop during
home position return
During a home position return, all axes rapid stop
operation was performed in the test mode of MT
Developer2.
• In case of proximity dog method, return to a point
before the proximity dog signal ON using JOG
operation or positioning operation, and perform the
home position return again.
• In case of proximity dog is off in count method, return to
a point before the proximity dog signal ON using JOG
operation or positioning operation, and perform the
home position return again.
