12.5 List of Error Codes
Error details and causes
• The data is not loaded from the servo amplifier
properly upon the home position return.
• The in-position signal is not turned ON within 1.5
seconds after moving an axis to the home position.
[Operation status at error occurrence]
The home position return does not complete.
Servo amplifier parameter "Function selection C-4
(PC17)" is not set to "0: Need to pass servo motor Z-
phase after power on" in the machine home position
return of scale origin signal detection method.
[Operation status at error occurrence]
The home position return does not start.
Home position return is started with the home position
return method which is not supported by the connected
device.
[Operation status at error occurrence]
The home position return does not start.
The zero point is not passed when the dog method,
count method or scale origin signal detection method
home position return is re-started, or data set method
home position return is executed.
[Operation status at error occurrence]
The home position return does not complete.
At the time of JOG starting, the JOG speed comes out
of a specified range.
[Operation status at error occurrence]
The JOG operation is not carried out when the JOG
speed is outside the setting range at the time of JOG
start.
The inching movement amount dose not satisfy the
*1
setting conditions . (The setting value is large.)
[Operation status at error occurrence]
The inching operation is not carried out when the
inching movement amount exceeds a JOG speed limit
at the time of inching start.
<When blocks are started simultaneously>
• The partner axis for simultaneous start is BUSY.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops immediately.
<When multiple axes are started and controlled
simultaneously>
• The same axis No. is set to multiple simultaneous
start axes.
• The own axis No. is set to a simultaneous start axis.
• The number of simultaneous start axes is outside the
setting range of 2 to 4.
• The partner axis for simultaneous start is BUSY.
• The "Simultaneous starting axis start data No." of the
start axis and the partner axis for simultaneous start
is 0 or is outside the setting range.
[Operation status at error occurrence]
At start: The system does not operate.
During operation: The system stops immediately.
Remedy
• Execute home position return again.
• Adjust the servo gain and in-position range, and
execute home position return again.
Set "0: Need to pass servo motor Z-phase after power
on" in the servo parameter "Function selection C-4
(PC17)".
Correct to the available home position return method.
Turn the motor more than one revolution using JOG or
positioning operation.
Bring the JOG speed into the setting range.
Set a smaller inching movement amount so that the
setting condition is satisfied.
Normalize the simultaneous start axis.
Normalize the simultaneous starting own axis start
data No. and the simultaneous starting axis start data
No.(1 to 3).
