How to clear errors or warnings
■When clearing errors for an individual axis
An error or warning state is canceled after the following processing is carried out by setting "1" in "[Cd.5] Axis error reset".
• Axis error detection signal is turned OFF.
• "[Md.23] Axis error No." is cleared.
• "[Md.24] Axis warning No." is cleared.
• "[Md.26] Axis operation status" is changed from "Error" to "Standby".
• "Axis warning detection ([Md.31] Status: b9)" is turned OFF.
When servo amplifier alarms cannot be reset even if error reset is requested, "0" is not stored in "[Cd.5] Axis
error reset" by the Motion module. It remains "1". Set "0" in "[Cd.5] Axis error reset" and then set "1" to
execute the error reset again by user side.
For the synchronous encoder axis, an error or warning state is canceled after the following processing is carried out by setting
"1" in "[Cd.323] Synchronous encoder axis error reset" for target axis.
• "b4: Error detection flag" of "[Md.325] Synchronous encoder axis status" is turned OFF.
• "[Md.326] Synchronous encoder axis error No." is cleared.
• "b5: Warning detection flag" of "[Md.325] Synchronous encoder axis status" is turned OFF.
• "[Md.327] Synchronous encoder axis warning No." is cleared.
■When clearing errors for all axes
The errors/warnings of the network and all axes are cleared at once by setting "1" to "SM4496 Intelligent module latest error
clear request" of the CPU module or by clicking the [Clear Error] button on the "Module Diagnostics" window of GX Works3.
The details of processing are the same as those for clearing errors for an individual axis.
