Turbo PMAC2 Realtime Express Controller
Software Setup
Motor Safety I-Variables
Ixx11 Motor xx Fatal Following Error Limit
By default, the controller will not check for following error and the drive will monitor for any
following errors. The reason is that the following error reported back to PMAC includes a delay
because of the network update rate, which can translate into unrealistic following errors at higher
speeds.
You can always turn this feature on by setting it to any number greater than zero. Make sure that
the fatal following error is less than the following error set on the drive, or the over current
protection will stop the drive with error 16 (Over-Current).
Note
When setting the Ixx11, make sure that you store the
same value in Ixx32 as the default value of your
following error. Ixx11 would be changed to a different
value while homing procedure and the value in Ixx32
would be written back once the homing is complete.
Ixx12 Motor xx Warning Following Error Limit
By default, the controller will not check for warning following error. The reason is that the
following error reported back to PMAC includes a delay because of the network update rate,
which can translate into unrealistic following errors at higher speeds.
Note
When setting the Ixx12, make sure that you store the
same value in Ixx35 as the default value of your
following error. Ixx12 would be changed to a different
value while homing procedure and the value in Ixx35
would be written back once the homing is complete.
