Step Description
5.
Select the "Cycle synchronization" tab, then set the "Synchronize drive with equidistant DP
cycle" check box.
The DP cycle time is applied and shown on this dialog box due to the settings you made in the
PROFIBUS network configuration. The DP cycle coefficient is adapted accordingly.
If you do not configure the cycle time in the network properties, the coefficients must be adapted
in this dialog box in order to obtain the relevant cycle time (example: 16 for a DP cycle of 2.00
ms.)
The DP cycle of the DP(DRIVE) interface is always an integer multiple of 0.5 ms, and is mainly
determined by the number and type of components to be operated on the network.
Note the drive-specific help in this dialog box when you determine the DP cycle.
6.
For this example set the "To" time coefficient to obtain a time of 0.5 ms. Do not change the
default value of the "Ti" coefficient.
7.
Confirm with "Calibration".
Click the button to make the changes described below:
• The constant bus cycle time is enabled
• The DP cycle in the master system is adapted to the drive properties
• All drive components of the same family receive the same parameters
8.
Close the dialog box with "OK."
9.
Save and compile the hardware configuration data, then download these to the PLC.
To generate system data for the HW Configuration and technology firmware, set the "Generate
technology system data" check box in the technology properties dialog box.
Note
Drive components of different families must be calibrated manually. To do so, note
down the set values and then transfer these to the corresponding dialog boxes.
