Remedy
Check the error code in CPU module.
(Refer to the "QCPU User's Manual (Hardware Design,
Maintenance and Inspection)".)
Review the program so that data is not written continuously to
the flash ROM. (Using "[Md.19]" in 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.)
With the setting brought into the setting range, turn the PLC
READY signal [Y0] from OFF to ON.
• Set AL and AM values which make "Movement amount per
rotation (AL)" × "Unit magnification (AM)" within 2147483647,
and then turn the PLC READY signal [Y0] from OFF to ON.
• With the setting brought into the setting range, turn the PLC
READY signal [Y0] from OFF to ON.
• Set the bias speed to not more than the speed limit value.
• With the setting brought into the setting range, turn the PLC
READY signal [Y0] from OFF to ON.
"[Pr.2] Number of pulses per rotation (AP)",
"[Pr.3] Movement amount per rotation (AL)",
"[Pr.4] Unit magnification (AM)"
Review these parameters.
