Message Contents
900 ROM PARITY A parity error occurred in the CNC, macro, or ser-
vo ROM. Correct the contents of the flash ROM
having the displayed number.
910 SRAM PARITY :
(BYTE 0)
A RAM parity error occurred in the part program
storage RAM. Clear the RAM, or replace the
911 SRAM PARITY :
(BYTE 1)
SRAM (SRAM/FROM module) or motherboard.
Subsequently, re–set the parameters and all oth-
er data.
912 DRAM PARITY :
(BYTE 0)
A RAM parity error occurred in the DRAM. Re-
place the module (CPU card) including the
913 DRAM PARITY :
(BYTE 1)
DRAM.
914 DRAM PARITY :
(BYTE 2)
915 DRAM PARITY :
(BYTE 3)
916 DRAM PARITY :
(BYTE 4)
917 DRAM PARITY :
(BYTE 5)
918 DRAM PARITY :
(BYTE 6)
919 DRAM PARITY :
(BYTE 7)
920 SERVO ALARM
(1–4 AXIS)
Servo alarm (first to fourth axis). A watchdog
alarm condition occurred, or a RAM parity error
occurred in the axis control card.
Replace the axis control card.
