Precautions for Correct Use Precautions for Correct Use
• To prevent operation from running out of control for an immediate stop, set an allowable
overspeed value in Overspeed Detection Level Setting at Immediate Stop (3615 hex). An
Overspeed 2 Error (Error No. 26.1) does not cause an immediate stop, therefore if this occurs,
the motor will switch to operation B (605E hex).
• Set a higher value for the Overspeed Detection Level Setting at Immediate Stop (3615 hex)
than for the Overspeed Detection Level Setting (3513 hex). If a value lower than the
Overspeed Detection Level Setting (3513 hex) is set, an Overspeed 2 Error (Error No. 26.1)
will occur before an Overspeed Error (Error No. 26.0). Thus an immediate stop will not occur. If
an Overspeed Error (Error No. 26.0) and an Overspeed 2 error (Error No. 26.1) occur at the
same time, the immediate stop will not occur, either.
• If the actual speed is not lower than 30 mm/s after the time set in the Error Detection Allowable
Time Setting (3614 hex) elapses from when an error that causes the operation A occurs, the
deceleration method switches to the operation B.
• If an error that causes the operation B also occurs during deceleration with the operation A,
the operation B has a priority as the deceleration method.
