APPENDIX 1.3 Major errors

These errors occur by control command from the external input signal or Motion SFC program, and the error codes 1000 to 1999 are used.

Major errors include the positioning control start errors, positioning control errors, absolute position system errors and system errors.

(1) Positioning control start errors (1000 to 1099)

These errors are detected at the positioning control start.

The error codes, causes, processing and corrective actions are shown in Table 1.8.

Error cause

 

 

 

• The external STOP signal of

 

 

the applicable axis turned on.

• The external signal FLS (upper limit LS) turned off at the forward direction (address increase direction) start.

• The external signal RLS (lower limit LS) turned off at the reverse direction (address decrease direction) start.

• The external DOG (proximity dog) signal turned on at the home position return start of the proximity dog type.

• The applicable axis is not servo READY state. (M2415+20n: OFF).

(1) The power supply of the servo amplifier is OFF.

(2) During initial processing after turning on the servo

amplifier.

(3) The servo amplifier is not installed.

(4) A servo error is occurred.

(5) Cable fault.

(6) Servo OFF command (M3215+20n) is ON.

• The servo error detection signal of the applicable axis (M2408+20n) turned on.
