Cancelling Errors - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

Cancelling errors

Continue errors (minor errors, or continue mode moderate errors) and warnings can be cancelled.
Cancelling errors
Use the following method to cancel errors after eliminating the cause.
■Cancelling method with GX Works3
Cancel with GX Works3 "Module diagnostics"
■Cancelling method with MT Developer2
Cancel with MT Developer2 "Motion Monitor"
■Cancelling method with special relay
Cancel with "Error reset (SM50)"
Errors that can be cancelled
The following is a list of errors that can be cancelled.
Error type
System common errors
Positioning/synchronous control output axis errors/warnings
*1
Servo alarms/warnings
Synchronous control input axis errors/warnings
*1
Machine errors/warnings
*1
G-code control errors
*1 Clears errors for all axes at the same time.
After cancelling errors, error-related special relays/special registers, and the LED display return to the condition prior to the
error. If the same error occurs again after cancelling the error, the error is registered again in the error history.
Operation when errors cancelled for each axis
• If an axis error reset or servo error reset is performed, the error detection signal for each axis, axis error No., and axis
warning No. are reset, however, diagnostic errors are not reset.
• When cancelling a G-code control error, "[St.3208] During G-code control (D54440.0+4s)" stays turned ON depending on
the error that occurred in G-code control. When an error is cancelled and operation started while "[St.3208] During G-code
control (D54440.0+4s)" is turned ON, the operation is still the same as when the error occurred thus operation can not start
correctly. When starting operation with "[St.3208] During G-code control (D54440.0+4s)" turned ON, reset the operation
status by turning OFFON "[Rq.3380] Reset command (D54226.4+2s)".
