ERW To enable the parameter, set "[AL. 9B Error excessive warning] selection" to "Enabled
(1 _ _ _)" in [Pr. PC60].
Error
excessive The setting unit can be changed with "Error excessive alarm/error excessive warning
warning level level unit selection" in [Pr. PC24].
Set this per rev. for rotary servo motors and direct drive motors. When "0" is set, 1 rev
will be applied. Setting over 200 rev will be clamped to 200 rev. Set this per mm for
linear servo motors. Setting "0" will be 50 mm.
When an error reaches the set value, [AL. 9B Error excessive warning] will
occur. When the error decreases lower than the set value, the warning will be
canceled automatically. The minimum pulse width of the warning signal is 100 [ms].
Set as follows: [Pr. PC73 Error excessive warning level] < [Pr. PC43 Error excessive
alarm level] When you set as [Pr. PC73 Error excessive warning level] ≥ [Pr. PC43
Error excessive alarm level], [AL. 52 Error excessive] will occur earlier than the
warning.
This parameter setting is available with servo amplifiers with software version B4 or
later.
