10.1.1 Description of Motion Errors
Motion errors in the MP2200/MP2300 include axis alarms detected for individual SERVOPACKs.
The failure location can be determined and appropriate corrections can be taken simply by checking
the contents of the Warning (IL††02) and Alarm (IL††04) monitoring parameters.
( 1 ) Motion Error Type 1
Alarms for the MP2200/MP2300 (including the MECHATROLINK-I or MECHATROLINK-II
functionality in the SVB-01 Module) are classified as follows:
[ a ] Warning (IL††02)
This parameter stores the contents of any warning that has occurred for the axis.
If the setting of a motion fixed or setting parameter is not within the setting range, the Fixed
Parameter or Setting Parameter Error Bit will turn ON.
Also, if the Deviation Abnormal Detection Error Level (OW††01 bit 0) is set to treat excessive
following errors as warnings, the Warning Bit will turn ON when an excessive following error
occurs.
Movement commands will continue when a warning has occurred. When the cause of the warning
has been removed, the Following Error and Servo Driver Error will be cleared.
For Setting Parameter Errors that occur while executing motion commands, correct the parameter
setting and then either execute the motion command again or recover operation by clearing the alarm.
[ b ] Alarm (IL††04)
This parameter stores the contents of any alarm that has occurred for the axis.
