Probable Cause
The torque limit was reached.
While calculating the moment of inertia,
the speed control was set to proportional
control by setting V_PPI in the Option
field to 1.
Corrective Actions
• When using the torque limit, increase
the torque limit.
• Double the set value of the moment of
inertia calculating start level (Pn324).
Operate the SERVOPACK with PI con-
trol while calculating the moment of
inertia.
