Servo Drive Control Sequence in TIA Portal

 

Servo Drive Control Sequence in TIA Portal

This procedure outlines the steps to open a pre-configured TIA Portal project, establish a connection to a Siemens SINAMICS drive unit, and access the master control panel to operate the motor for testing or optimization.

Step 1: Launch TIA Portal and Open Existing Project

1. Launch the Siemens TIA Portal V18 software.
2. In the Portal View start screen, ensure the Start tab is selected on the left menu.
3. Click on Open existing project.
4. In the 'Recently used' list, locate and select the project named "PMSM.ap18". The path is shown as: C:\Users\Student\Documents\Automatisierung\PMSM.
5. Click the Open button in the bottom right corner.

Step 2: Confirm Project Open and Transition to Project View

 

1. A "First steps" screen will appear, confirming that 'Project "PMSM" was opened successfully.'
2. To proceed with the hardware configuration and online connection, navigate to the bottom left corner of the screen.
3. Click on the arrow icon next to Project view to switch from the simplified Portal view to the detailed Project view.

Step 3: Configure Communication Interface and Go Online

 

1. The main Project View will open. In the top toolbar, click the Go online button (usually represented by an icon of two connecting plugs). A "Go online" dialog box will appear.
2. In the dialog box, set up the communication path for "Drive_unit_1":
• Type of the PG/PC interface: Select PN/IE (Profinet/Industrial Ethernet).
• PG/PC interface: Select your computer's actual network card from the dropdown (e.g., "Realtek PCIe 2.5GbE Family Controller").
• Connection to interface/subnet: Select the specific port or subnet (e.g., "Direct at slot 'CU X127'").
3. Click the Start search button. The software will scan the network for compatible devices.
4. Once the scan is complete, and a compatible device (e.g., drive_unit_1 with type S120/S150 PN) is listed under 'Select target device' with a green checkmark indicating successful connection, click the Go online button at the bottom right of the dialog.
5. Step 4: Address Default Connection Path Prompt

 

1. Depending on your TIA Portal settings, a prompt titled "Default connection path for online access" may appear. This asks if you want to save the settings you just configured as the default.
2. Click Yes to save these interface settings for future use. The software will continue connecting to the online drive.

Step 5: Navigate to the Drive Axis Commissioning Screen

 

1. Observe the Project tree on the left. If the online connection is successful, you will see green dots/icons next to the project items.
2. Expand the Project tree structure as follows: PMSM > Drive_unit_1 [S120 CU310-2 PN] > Drive_axis_1 [PM].
3. Double-click on the entry Rotate & optimize.
4. In the central work area, the "Control panel" for the selected axis will open. Currently, most functions will be greyed out and inactive because Master Control has not yet been assumed by TIA Portal.

Step 6: Activate Master Control and Accept Safety Warning

1. On the Control panel screen in the central area, locate the 'Master control' group. Click the Activate button.
2. A critical safety pop-up window titled "Activate master control" will appear. This window warns that you are about to assume manual control of the drive, overriding safety shutdowns from higher-level controllers.
3. Review the monitoring time (default is 2000 ms).
4. Check the box for the warning: "By disabling this option, you can only stop the motor using the control panel buttons... a hardware solution for the Emergency Stop circuit is mandatory." (or similar applicable safety acknowledgment).
5. Read the safety message at the bottom: "Non-compliance can result in injury and material damage." Check the confirmation box "Continue without quick stop function...".
6. Click OK to assume Master Control. The Control panel functions in Step 5 will now become active, allowing you to manually enable the drive and set speed setpoints for testing.

Step 7: Enable the Drive and Set Speed Setpoint

1. Verify the drive's operational state in the "Drive status" section; both "Ready for switching on" and "Operation enabled" should display green checkmarks indicating the drive is ready.
2. In the "Control" section, enter your desired target speed into the "Speed " input field (for example, 500.00 rpm).
3. Click the "Forward" or "Backward" buttons to command the motor to run at the specified speed in the chosen direction.
4. Observe the real-time feedback in the "Actual values" section at the bottom of the window, which monitors parameters such as “Output frequency (f)”, “Current actual value torque-generating (Iq)”, “Current actual value field-generating (Id)” and so on.
