13.5.6.3.11 Sequence of operations
1. Safe and translate your project.
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, double-click ‘Project tree è ...CPU... è Watch and force tables
è Add new watch table’.
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 ‘Name’ the designation
‘ComWaitCycles’ as ‘DEC’ and enter at ‘Modify 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.
5. Before you can control an inverter drive, it must be initialized with FB 881 -
VMC_InitV1000_RTU.
Ä
Chap. 13.5.7.10 ‘FB 881 - VMC_InitV1000_RTU - Modbus
RTU initialization’ page 507
For this enter in the watch table at ‘Name’ the designation ‘A1_InitExecute’ as
‘Boolean’ and enter at ‘Modify value’ the value ‘True’ . Activate the modification of
the variables and start the transmission of the modified values.
ð
The inverter drive is initialized. After execution, the output Done returns TRUE.
In the event of a fault, you can determine the error by evaluating the ErrorID.
Do not continue as long as the Init block reports any errors!
6. After successful initialization, the registers of the connected inverter drives are cycli-
cally processed, i.e. they receive cyclical jobs. For manual control, you can use the
FB 882 - VMC_AxisControlV1000_RTU to send control commands to the appro-
priate inverter drive.
Ä
Chap. 13.5.7.11 ‘FB 882 - VMC_AxisControlV1000_RTU -
Modbus RTU Axis control’ page 509
7. Create the parameters of the FB 882 - VMC_AxisControlV1000_RTU for control
and query in the watch table.
8. Save the watch table under a name such as ‘V1000’ .
9. Activate the corresponding axis by setting AxisEnable. As soon as this reports Axis-
Ready = TRUE, you can control it with the corresponding drive commands.
