Configuring drives with SINAMICS Integrated isochronously



Requirements

STEP 7 , V16 or higher

SINAMICS Startdrive , V16 or higher

Procedure

Add a SIMATIC Drive Controller to your project.
The network view displays the components of a SIMATIC Drive Controller: SIMATIC S7-1500 CPU and SINAMICS Integrated, networked through PROFIdrive Integrated.

Open the device view of SINAMICS Integrated. Configure the SINAMICS S120 drive system with its drive objects.
You can find the relevant details in the SINAMICS S120 with Startdrive commissioning manual.

Select the drive control in the SINAMICS Integrated device view.
Check the default PROFIdrive **s In the properties, under "Integrated_1" > "Telegram configuration" in the "General" tab. Make changes if required.
The following default settings are made automatically:

- Automatic speed control: Frame 393

- Supply: Frame 370

- Drive axes: Frame 105

Create the axis technology objects. You create the axis technology objects under "Technology objects > Add new object" in the project tree.

Assign the configured drives to the axis technology objects.

- Open the configuration of the technology object.

- Navigate to "Hardware interface" > "Drive".

- Select the "PROFIdrive" entry from the "Drive type" drop-down list.

- Select the "Antrieb" entry from the "Data connection" drop-down list.

- Select a SINAMICS Integrated drive axis from the "Drive" list.

Only drives for which a suitable PROFIdrive frame has been configured are available for selection in the "Drive" list. You can find which PROFIdrive frames are supported by the SINAMICS Integrated in the S7?1500T Motion Control function manuals.


圖片: Assigning drives to the technology objects

The technology object is connected to the drive. When the drives are assigned to the axis technology objects, the following takes place:

- MC-Servo is created (if not already present)

- The TPA OB Servo is entered as the process image for all PROFIdrive **s

Once you have configured all axis technology objects, switch back to the drive configuration if necessary. You can use the "Device configuration" button.

提示 With SINAMICS Integrated, all frames must be operated in isochronous mode on OB Servo (OB 91) or isochronous mode interrupt OB (OB 6x). STEP 7 checks compliance with this rule when compiling the SIMATIC Drive Controller. Exception: If you insert a SIMATIC Drive Controller in your project from the module catalog, "--- (none)" is entered as the organization block for the drive control. If you do not configure any other drive objects, you can also compile and download to the device without isochronous mode.

Setting the clock system

You have configured SINAMICS Integrated as isochronous. Next, set the clock system.

Make the following settings in accordance with whether you are operating SINAMICS Integrated in independent or coupled isochronous mode:

For independent isochronous mode:

- Set the required cycle time.

- Assign the "MC Servo" OB the clock system of SINAMICS Integrated.

For coupled isochronous mode:

- Assign the clock system of SINAMICS Integrated the leading clock system.
You can find details of how to assign the leading clock system in Setting the clock system.
