Chapter 7 Error Codes 7.1.5 AH20MC-5A 7-17 Error code Description LED indicator status CPU Module BUS Error FAULT 16#A00D The setting of speed (I) of the single-axis motion is incorrect. Blink 16#A00E The setting of speed (II) of the single-axis motion is incorrect. Blink 16#A00F The setting of the speed (V ) of returning to zero is RT incorrect. Blink 16#A010 The setting of the deceleration (V ) of returning to CR zero is incorrect. Blink 16#A011 The setting of the JOG speed is incorrect. Blink 16#A012 The positive pulses generated by the single-axis clockwise motion are inhibited. Blink 16#A013 The negative pulses generated by the single-axis counterclockwise motion are inhibited.
Blink 16#A014 The limit switch is reached. Blink 16#A015 The device which is used exceeds the device range. Blink 16#A017 An error occurs when the device is modified by a 16-bit index register/32-bit index register. Blink 16#A018 The conversion into the floating-point number is incorrect. Blink 16#A019 The conversion into the binary-coded decimal number is incorrect. Blink 16#A01A Incorrect division operation (The divisor is 0.) Blink 16#A01B General program error Blink 16#A01C LD/LDI has been used more than nine times. Blink 16#A01D There is more than one level of nested program structure supported by RPT/RPE. Blink 16#A01E SRET is used between RPT and RPE.
Blink 16#A01F There is no M102 in the main program, or there is no M2 in the motion program. Blink 16#A020 The wrong instruction is used, or the device used exceeds the range. Blink Error code Description LED indicator status CPU Module BUS ERROR FAULT 16#A002 The subroutine has no data. Blink 16#A003 CJ, CJN, and JMP have no matching pointers. Blink 16#A004 There is a subroutine pointer in the main program. Blink 16#A005 Lack of the subroutine Blink 16#A006 The pointer is used repeatedly in the same program. Blink 16#A007 The subroutine pointer is used repeatedly. Blink 16#A008 The pointer used in JMP is used repeatedly in different subroutines.
Blink 16#A009 The pointer used in JMP is the same as the pointer used in CALL. Blink 16#A00B Target position (I) of the single speed is incorrect. Blink 16#A00C Target position (II) of the single-axis motion is incorrect. Blink
