3 POSITIONING DEDICATED SIGNALS
(5) Major error code storage register (D7+20n) ............. Monitor device
(a) This register stores the corresponding error code (Refer to APPENDIX 1.3)
at the major error occurrence. If another major error occurs after error code
storing, the previous error code is overwritten by the new error code.
(b) Major error codes can be cleared by an error reset command (M3207+20n).
(6) Servo error code storage register (D8+20n) ......... Monitor device
(a) This register stores the corresponding error code (Refer to APPENDIX 1.4)
at the servo error occurrence. If another servo error occurs after error code
storing, the previous error code is overwritten by the new error code.
(b) Servo error codes can be cleared by an error reset command (M3208+20n).
(7) Home position return re-travel value storage register (D9+20n)
....…….. Monitor device
If the position stopped in the position specified with the travel value setting
(Refer to Section 6.23.1) after the proximity dog ON by a peripheral device is not
zero point, it made to travel to zero point by re-travel in the Motion CPU. The
travel value (signed) of making it travel to zero point by re-travel at this time is
stored. (Data does not change with the last value in the data setting type.)
The following value is stored according to the number of feedback pulses of the
motor connected.
Number of feedback pulses Storage data
Less than 131072[PLS] Feedback pulses
131072[PLS] or more, 262144[PLS] or less 1/10 of feedback pulses
More than 262144[PLS] 1/10000 of feedback pulses
(8) Travel value after proximity dog ON storage register
(D10+20n, D11+20n) ………………………………… Monitor device
(a) This register stores the travel value (unsigned) from the proximity dog ON to
home position return completion after the home position return start.
(b) The travel value (signed) of the position control is stored at the time of
speed/position switching control.
