A
In addition to the general section in chapter "Task Management for MOVIDRIVE
®
A and
B", this section provides specific implementation information for MOVIDRIVE
®
A: The
motion sequence with the positioning commands is programmed in task 1.
Program the following functions in task 2:
• Rapid, time-critical processes
•Calculations
• Monitoring for system values
• Communication with the SEW operator terminals
• Copying variables cyclically to the oscilloscope variables H474, H475
• Formatting the fieldbus/SBus process data with a machine control function or
another MOVIDRIVE
®
In this way, IPOS
plus®
also performs these functions when the interrupt routine is active
in task 1.

5.4.1 Processing time for task 1 / task 2
The factory setting for the task processing time is:
• Task 1: 1 command/ms (P938 = 0)
• Task 2: 2 commands/ms
You can speed up the processing time in both tasks to include up to 9 additional com-
mands per ms. You can assign the additional commands for task 1 using parameter
P938 (index 8888) and for task 2 using parameter P939 (index 8962). This means that
a maximum of 1 + 9 = 10 commands can be performed in task 1 and 2 + 9 = 11 in
task 2.
