Error name
The calculation result of the following
equation is smaller than 0 or larger than
65536.
0 ≤
• In the unit of degree, the set value of
the detailed parameter 1 "Software
stroke limit upper limit value" is
outside the setting range.
• In a unit other than degree, the
software stroke limit upper limit value
is smaller than the software stroke
limit lower limit value.
• In case unit is "degree", the set range
of the detailed parameter 1 "Software
stroke limit lower limit value" is outside
the setting range.
• In case unit is different than "degree",
the software stroke limit upper limit
value is smaller than the software
stroke limit lower limit value.
