Setting the excessive error detection width
Set an excessive error alarm detection width to each operation parameter group.
An alarm is detected when the position droop (between position command and feedback) exceeds the setting value. The
standard setting value is calculated from the feedrate using the following equation. The excessive error alarm can occur easily
when the load inertia is large or the auto-tuning response is lowered. Raise the excessive error detection width in these cases.
OD(N) = Aspeed(N) / 1000 (°or mm)

Explanations
Set the motor output torque limit value when "operation pa-
rameter group n" is selected. At the default value, the torque
is limited at the maximum torque of the motor specifications.
Set the default value when torque limiting is not required.
Explanations
Set the excessive error detection width when "operation pa-
rameter group n" is selected. The excessive error alarm (S03
0052) will be detected when the position droop becomes larg-
er than this setting value.
