Failure to follow these instructions can result in death, serious injury, or equipment damage. |
For rotary drives, the TrackingDeviationLimit is limited to 1000 units (load side) or 500 revolutions (motor side). The lower one of the two limits is the active limitation.
For linear drives, there is only the limitation to 1000 units.
If the maximum tracking deviation is exceeded, then the diagnostic message 8132 Tracking deviation limit exceeded with the respective response is triggered. If eight times the maximum tracking deviation value is reached or exceeded, a diagnostic message 8111 Tracking deviation shutdown is issued. A too large parameter value causes a delayed triggering of diagnostic messages with the corresponding reactions.
NOTE: The parameter value is transferred from the master to the slave via the parameter channel of the Sercos at every access. Typically, this takes about 10 ms. However, times up to 1 s can occur if there is a lot of data transferred on the parameter channel.
This parameter has no effect for asynchronous motors in open-loop V / f mode (ControlMode = open-loop control / 1).
