Speed Error Monitor Enable
Position Error Monitor Enable
Feedback Speed Sampling Period
Speed Error Monitor Wait Time
Speed Error Limit Value
Set whether or not to monitor the speed error between the command speed and feedback
speed.
If the speed error exceeds [Speed Error Limit Value], a speed error over error occurs.
Set whether or not to monitor the position error between the command position and feedback position.
Monitor position error based on the absolute coordinates of command position and feedback position.
Monitor position error after a command starts until positioning is completed.
If the position error exceeds [Position Error Limit Value], a position error over error occurs.
With this monitoring, the PCU is equipped with double check functions including the positioning
completed signal via the positioning monitor time when using the positioning completed signal
from the Servo Drive .
Set the sampling cycle at which to measure the feedback speed.
Set the time from the start of the command speed output, until the speed error monitor start.
Set the speed error you want to monitor as an amount of movement per speed sampling time.
To monitor the error of 10,000 command unit/s at the feedback speed sampling cycle [5 ms],
[Speed Error Limit Value] is calculated as follows:
Speed error limit value = Monitor speed (command unit/s) × Feedback speed sampling cycle (s)
Accordingly, set [50] for the speed error limit value.
monitoring is currently valid (axis busy flag ON), and ends upon completion of operation (axis busy
flag OFF).
In the case of linear interpolation or circular interpolation by memory operation, the error monitor
function remains active on all configuration axes whose monitoring is valid in the same task, until
the series of operations are completed (until the memory operation busy flag turns OFF).
monitoring, error monitoring continues to the next sequence if the [Positioning Completed Input
Monitor Valid] setting is disabled. If the [Positioning Completed Input Monitor Valid] setting is
enabled, speed error monitoring will start when the next sequence commences after an elapse of
the speed error monitor wait time.
If you have selected [Automatic] under [End Pattern] for memory operation during speed error
Under the error monitor function, monitoring starts at the start of operation of the axis whose
