13.5.5.3.11 Sequence of operations
1.
Safe your project with ‘Station è Safe and compile’.
2. Transfer your project to your CPU.
ð
You can take your application into operation now.
CAUTION!
Please always observe the safety instructions for your inverter
drive, especially during commissioning!
3. A watch table allows you to manually control the inverter drive. To create a watch
table, choose ‘PLC è Monitor/Modify variables’.
ð
The watch table is created and opened for editing.
4. First adjust the waiting time between 2 jobs. This is at least 200ms for a V1000
inverter drive. For this enter in the watch table at ‘Symbol’ the designation
‘ComWaitCycles’ as ‘Decimal’ and enter at ‘Control value’ a value between 200
and 400.
To increase performance, you can later correct this to a smaller
value as long as you do not receive a timeout error (80C8h). Please
note that some commands, such as MoveVelocity, can consist of
several jobs.
