Center coordinate setting error
When one of the following applies:
- Start point = center coordinate
6
- End point = center coordinate
- Center coordinate is outside of the
-2,147,483,648 to 2,147,483,647 PLS range
Table operation start No. error
3000 The table No. is executed outside of the range 0 to
299.
Jump No. fault
3001 The jump No. for the table information is set outside
the range 0 to 299.
Command format fault
3002 The operation information of the table information is
set by a non-defined number.
Current value overflow at absolute value detection
system
3004
The converted pulse data of the current address
exceeds 32 bits.
3005 Manual pulse generator input error
Servo end error
4002 The in-position signal did not turn ON during the
servo end determination time.
Servo ready error
4003 The servo motor ready signal did not turn ON at
operation start or during operation.
Forward rotation limit, reverse rotation limit error
• The forward rotation limit (LSF) and reverse
4004 rotation limit (LSR) are ON.
• The forward rotation limit 2 (FLS) and reverse
rotation 2 (RLS) limit are ON.
Software limit error
4005 The current address exceeds the software upper
and lower limits.
4006 The servo amplifier emergency switch is ON.
ABS error
The current position could not be established.
4007
Illegal origin data
4008 The backup data for restoring the absolute position
is illegal.
13.2 Check Error Code
Action
-
Change the setting value in buffer memory so that it
is within the setting range.
Change the setting value of the corresponding buffer
memory so that the converted pulse data is smaller
than 32-bit data.
Change the program in the PLC main unit so that
positioning control start commands do not overlap.
Change the program in the PLC main unit so that
only one operation pattern is selected.
Check the center coordinate setting and set so that a
circle is formed.
Change the table operation start No. to 0 to 299.
Change the jump No. for the table information to 0 to
299.
Change the operation information of the table
information.
Turn the power OFF, or perform a mechanical zero
return or data set type zero return.
Change the pulse generator input (numerator) and
pulse generator input (denominator) settings.
Increase the servo end determination time setting.
Check the servo motor and encoder cable.
• Check the wiring of the forward/reverse rotation
limit, limit switches and the program.
• Check the external signal selection (positioning
parameter) settings.
• Retract from the forward/reverse rotation limit by
JOG operation or manual pulse generator input
operation.
• Correct the target address.
• Set the current value to within the software limit
range by JOG operation manual pulse generator
input operation.
Check the servo motor and encoder cable.
• Make sure to use a servo motor with absolute
position detection.
• Make sure to use the battery for the servo motor
to retain the origin position.
• Make sure that the absolute position detection
system in servo parameters is valid.
• Check the servo motor and encoder cable.
Execute a zero return.
