APPENDIX 3.2 Reading error code
The program example for reading error code at the error occurrence is shown below.
The following signals are used to determine whether or not an error has occurred:
• Minor errors, major errors ………. Error detection signal (M2407+20n)
• Servo errors ……………………... Servo error detection signal (M2408+20n)
POINT
(1) The following delay occurs in the turning off to on of M2407+20n/M2408+20n
and storage of the error code.
(a) If the PLC program scan time is 80[ms] or less, there will be a delay of up to
80[ms].
(b) If the PLC program scan time is 80[ms] or more, there will be a delay of up
to one scan time.
The error code is stored to each error code stprage area after turning on
M2407+20n/M2408+20n, and then read the error code.
