The Maestro can manage up to 64 axes on a standard application. However, fewer
axes can be managed on applications requiring fast updates.
The Bus Load graphs show how many drives can be managed as a function of update time and bus speed. |

For example, the Maestro can manage 4 axes on an application
that requires an update every 1 msec running at a 70% load
on an 800 Kbit/s bus.
On the other hand, the Maestro can manage up to 50 axes on
an application that requires an update every 20 msec running
at a 70% load on an 1000 Kbit/s bus.

The graph above can be used as a yardstick to
determine the number of updates needed to produce an acceptable
path. In this case, the number of updates is a function of the
diameter, speed and maximum allowable interpolation error.
For example, if the required velocity is 100,000 counts/sec
along a 1000 count diameter path, and the allowable interpolation
error is 10 counts, then the Maestro must perform an update
every 4 msec. |
