Operation status at error occurrence
■Description
• The Z.ABRST instruction is executed with the
status set to other than 0 (at the start of
communication with the servo-amplifier).
• The status of the Z.ABRST instruction is
changed during absolute position restoration
(during communication with the servo-amplifier).
• The ZP.PSTRT instruction is executed with the
start No. set to other than 1 to 600, 7000 to 7004
and 9001 to 9004.
• The ZP.TEACH instruction is executed with the
teaching data selection set to other than 0 and 1.
• The ZP.TEACH instruction is executed with the
positioning data No. set to other than 1 to 600.
• The instruction of a non-existent axis is specified
by the Z.ABRST, ZP.PSTRT or ZP.TEACH
instruction.
■Operation status at error occurrence
The function corresponding to the instruction is not
executed.
■Description
Data is written to the flash ROM continuously 25
times or more from the program.
■Operation status at error occurrence
At start: The system will not operate.
■Description
Mismatching occurs between the CPU module and
LD75.
■Operation status at error occurrence
At start: The system will not operate.
CHAPTER 15 TROUBLESHOOTING
Action/Related buffer memory address/Set
range (Setting with program)
■Action
• When executing the Z.ABRST instruction, set
the status to 0 ( Page 620, Section 14.3)
• Do not change the status during absolute
position restoration by the Z.ABRST
instruction.
• When executing the ZP.PSTRT instruction,
set the start No. to within the setting range
( Page 625, Section 14.4)
• When executing the ZP.TEACH instruction,
set the teaching data selection and positioning
data No. to within the setting range ( Page
629, Section 14.5)
• Do not specify the instruction of a non-existent
axis by the Z.ABRST, ZP.PSTRT and
ZP.TEACH instructions. ( Page 620,
Section 14.3 to Page 629, Section 14.5)
■Setting range
Z.ABRST status
0: Communication complete (received from the
servo amplifier)
ZP.PSTRT start No.: 1 to 600, 7000 to 7004,
9001 to 9004
ZP.TEACH teaching data selection
0: The current feed value is written to the
positioning address.
1: The current feed value is written to the arc
address.
ZP.TEACH positioning data No.: 1 to 600
■Action
Review the program so that data is not written
continuously to the flash ROM. (Using [Md.19] in
system monitor data ( Page 182, Section
5.6.1), the number of flash ROM write times can
be monitored.)
(If this error has occurred in a proper using
method, writing is enabled by resetting the error,
switching power OFF, then ON, or resetting the
CPU module.)
■Action
A trouble occurs. Repair.
