setting range.
905
Rotation direction
setting error
The set value of the basic parameter 1
"Rotation direction setting" is outside
the setting range.
906
Outside bias speed
range
• The set value of the basic parameter 1
"Bias speed at start" is outside the
setting range.
• The bias speed exceeds the speed
limit.
910
Outside speed limit
value range
• The set value of the basic parameter 2
"Speed limit value" is outside the
setting range.
• The value obtained by the conversion
of the speed limit value with respect to
the frequency exceeds the maximum
output frequency of the unit.
• The speed limit value is smaller than
the OPR speed.
When the power is turned ON or
PLC READY signal (Y0) is turned
from OFF to ON:
QD75 READY signal (X0) is not
turned ON.
At start:
The system will not operate.

not turned ON.
921
Software stroke limit
upper limit
• 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.
