Corrective Action
•
The command speed is too high.
•
Reconsider the command speed.
A
•
Servo system CPU fault.
•
Change the servo system CPU.
•
There is excessive variation in the
position commands from the servo
system CPU; commanded speed is
too high.
•
Check the commanded speed, and the
number of pulses per revolution and
travel value per revolution in the fixed
parameters.
