BUS FAULT ERROR
16#A002 The subroutine has no data. Blinking
16#A003 CJ, CJN, and JMP have no matching pointers. Blinking
16#A004 There is a subroutine pointer in the main program. Blinking
16#A005 Lack of the subroutine Blinking
16#A006 The pointer is used repeatedly in the same program. Blinking
16#A007 The subroutine pointer is used repeatedly. Blinking
16#A008
The pointer used in JMP is used repeatedly in different
subroutines.
Blinking
16#A009
The pointer used in JMP is the same as the pointer used in
CALL.
Blinking
16#A00A The pointer used in JMP is the same as a subroutine pointer. Blinking
16#A00B Target position (I) of the single speed is incorrect. Blinking
16#A00C Target position (II) of the single-axis motion is incorrect. Blinking
16#A00D The setting of speed (I) of the single-axis motion is incorrect. Blinking
16#A00E The setting of speed (II) of the single-axis motion is incorrect. Blinking
16#A00F The setting of the speed (V
RT
) of returning to zero is incorrect. Blinking
16#A010
The setting of the deceleration (V
CR
) of returning to zero is
incorrect.
Blinking
16#A011 The setting of the JOG speed is incorrect. Blinking
16#A012
The positive pulses generated by the single-axis clockwise
motion are inhibited.
Blinking
16#A013
The negative pulses generated by the single-axis
counterclockwise motion are inhibited.
Blinking
16#A014 The limit switch is reached. Blinking
16#A015 The device which is used exceeds the device range. Blinking
16#A017
An error occurs when the device is modified by a 16-bit index
register/32-bit index register.
Blinking
16#A018 The conversion into the floating-point number is incorrect. Blinking
16#A019
The conversion into the binary-coded decimal number is
incorrect.
Blinking
16#A01A Incorrect division operation (The divisor is 0.) Blinking
16#A01B General program error Blinking
16#A01C LD/LDI has been used more than nine times. Blinking
16#A01D
There is more than one level of nested program structure
supported by RPT/RPE.
Blinking
16#A01E SRET is used between RPT and RPE. Blinking
16#A01F Incorrect division operation (The divisor is 0.) Blinking
16#A020
The wrong instruction is used, or the device used exceeds the
range.
