Duty monitor
An overload error appears to warn the motor is working too hard during tough robot
operation. In these cases, either the robot acceleration or maximum speed must be
lowered, or the robot stop time increased (lower the duty). On the other hand, if you want
to shorten the cycle time even further, when there is currently no overload, you can raise
the acceleration or maximum speed, or shorten the robot stop time (raise the duty).
Viewing the duty monitor allows you to easily check the current robot operating status to
find out how hard the robot can still work versus overload criteria. By checking the duty
monitor, you can repeatedly change the settings and view the available duty to obtain
ideal operating conditions.
