• Communication, Control options (Ethernet IP, Onboard IO, PN, etc.)
• Topology, component changes
• Motor, Rotation, Speed Options

Frequently, customers use different drive projects to handle these changes, consuming valuable controls programming resources to set up each machine. This blog will explain how to use a drive’s memory areas to save multiple configurations onto the same drive CF card memory.

SINAMICS Memory Structure

To better understand multiple configurations, it is important to understand the SINAMICS memory structure.

This diagram demonstrates how data is transferred from the Offline project (Starter or Portal) to the drive’s active memory (RAM) through download to the drive or upload from the drive. Additionally, the Online vales can be saved to Read-only memory (ROM) through the function “Copy RAM to ROM”. Lastly, when the drive is power cycled, the RAM is loaded from the Read-only memory on the CompactFlash card (CF Card).

Reading & Writing to ROM Areas (other than default)

During typical use, the drive utilizes the first Read-only memory area, ROM (1). However, there are several others on the CF card. For G120 drives, there are (3) supplementary memory areas: 10, 11, 12. For S120, there are (6) memory areas: 10, 11, 12, 1111, 1112, 1113. To save a configuration to a ROM area, simply set p0977 (S120/S150) or p0971 (G120) to the intended area. Always save ROM (1) for the active configuration (for next boot).

Similarly, a saved configuration can be loaded from any ROM area using p0976 (S120/150) or p0970 (G120). NOTE: The drive will default to ROM (1) on the next power cycle. Be sure to save the active configuration to ROM (1).

Example: Control through Onboard IO vs Profinet

For this example, there will be (2) options: Control through CU on-board IO vs Control signals from Profinet.

Step 1: Setup Drive for On-board IO, then save the configuration to ROM (10).

Step 2: Setup Drive for Profinet Communications, then save the configuration to ROM (11).

All memory areas are stored on the CF card. To transfer these setups from Machine 1 to Machine 2, simply copy the all contents of Machine 1 CF card to Machine 2 CF card using Windows file explorer.

Now, to activate the Onboard IO option, simply load ROM (10) to RAM; then copy RAM to default ROM (1).

Now, the controls team can set up an initial model once and your production team can support change the active configurations from the same CF card image.

1. Add the drive to Devices & Networks. If the drive has separate Control and Power Units, add the Power unit in the Device View of the Control Unit.
2. Assign the IP address and Profinet Name in Devices & Networks. This IP address must be unique and on the same subnet as the PLC.
3. Setup Safety Telegrams in Devices & Networks. Be sure to assign the Partner data area so that no tags are overlapping with tags used for logic.
4. Assign Unique F-Addresses in Devices & Networks. Profinet F-addresses are only assigned through Portal and do not have the physical jumpers Profibus drives have.
5. Set IP address and Profinet Name in the drive to match the one assigned in Devices & Networks. This is done through the Online Access > Device Interface> Online & Diagnostics > Functions. If the device has had a previous IP address assigned, make sure to reset the IP to factory default first. This will reset only the IP address and Name, not any previously assigned parameters or safety functionality. If a factory reset is not done, the IP address may return to the original setting after a few power cycles.
6. Commission drive parameters using the commissioning wizard built into Portal and the specifications found on the motor faceplate.
7. Commission drive safety through the functional view of the Parameter option. If commissioning multiple similar drives and copying the drives in the Device & Networks, you must “Activate the Safety Commissioning Mode” while online with each drive individually, even if no settings need to be changed.
8. Test the drive by manually moving it in Portal’s control panel.
9. Upload from drive to save motor parameters in Portal for later reference.

Here is a more detailed description of the process found on Siemen’s website.
