3.6 Connecting CU230P-2 CAN to CAN bus Description This section describes how the inverter is physically connected to the CAN bus. The communication settings are described in the Control Unit operating instructions in the section "Communication settings for CANopen". The Control Unit CU230P-2 CAN has a 9-pin sub D connector underneath the Control Unit for integrating the inverter into the CANopen fieldbus system. This connector has short-circuit-proof, isolated pins.
PAGE 11
Note Important note for setting the CANopen address The address can only be set via p8620 if the address 0 or 127 is set on the DIP switches of the Control Unit. If the address switches are set to a value ≠ 0 or 127, this address is always active and p8620 is read-only.
PAGE 12
4 Commissioning Description Commissioning must have been completed before a motor can be operated at the inverter (Control Unit and Power Module). To do this, proceed as follows: ● Commission the drive using either IOP or STARTER ● Download a valid parameter set via – Memory card – IOP – STARTER Further, the following prerequisites must be fulfilled to operate a motor from an inverter: ● The rated inverter current must, as a minimum, be just as high as that of the motor.
PAGE 13
4.1 Commissioning with STARTER Prerequisites and preparations for commissioning with STARTER ● STARTER has been installed on the commissioning PC STARTER can be ordered under Order No. 6SL3072-0AA00-0AG0 as DVD or can be updated to the latest version from the Internet under the following link (http://support.automation.siemens.com/WW/view/en/10804985/133100). Further, the SINAMICS G120 PC - inverter connection kit - 2 (USB cable and STARTER DVD) is available under Order No. 6SL3255-0AA00-2CA0.
PAGE 14
4.1.2 Installing USB drivers Description If you connect your inverter to your PC for the first time via the USB interface, you will be prompted by the following screen to install the driver for the SINAMICS G120 Control Unit. Insert the driver CD supplied with the CU into the CD-ROM drive. Before installation, read the license conditions. These are saved on the CD under the "License.txt" name. Then click on "Next" and select "Continue Anyway" in the adjacent screen.
PAGE 15
4.1.3 Creating a STARTER project Create a STARTER project using the Project Wizards Start the Wizards (Project/New with wizard) and search, as shown in the adjacent diagram, for the inverters connected to the PC. In the next window (not shown here), enter a descriptive project name and if required, also a comment. Click on "Next" and the adjacent dialog box is displayed from where you can configure the PC interface.
PAGE 16
You will require the number of the COM connection to continue setting the PC interface. A description is provided in Section Setting the COM interface (Page 31) as to how you can read this from the control panel and if required, change it. To set the PC interface, in the adjacent screen, select the "PC COM-Port (USS)" interface (①) and click on "Properties" (②). In the following dialog box, select the number of the COM connection that you defined in the Section "Setting the COM interface" (①).
PAGE 17
In this window, press the "Continue" button - a dialog box is displayed with a summary of the settings that you made. Close the Project Wizards using the "Finish" button and then you can continue with the remaining commissioning steps. 4.1.4 Go online with the inverter Description When the Project Wizards are exited, the project is set-up under the specified path and is simultaneously opened.
PAGE 18
If the data that are saved in STARTER for the inverter involved (offline data) are different from those of the inverter (online data), then the adjacent screen is displayed. First, press the "Load HW configuration to PG" button to overwrite the offline data with the data of the inverter and then the "Close" button and proceed with the commissioning. Note If you first press the "Close" button, then the online connection is terminated before any data has been changed. 4.1.
PAGE 19
The following message could be displayed if your inverter is not part of a SIMATIC control. This has no significance when commissioning the inverter and can be closed.
PAGE 20
4.1.6 Carrying out commissioning Description The Commissioning Wizard starts with the screen form to set the closed-loop control. Using the dropdown menu, select one of the listed open-loop or closed-loop control types and click on "Continue". Screen forms then follow one after the other for ● Setpoint and command sources Note: For CU230P-2 DP CUs, the PROFIdrive telegram must be changed to 999 before the command and setpoint sources can be changed.
PAGE 21
The next ON command starts the motor data identification. This completes the first commissioning. 4.2 Restoring the factory settings using STARTER The inverter is reset to the delivery condition by restoring the parameters to the factory setting. Note The reset operation is not applied to parameters p0014, p0100, p0201, p0205 or the communication parameters. Motor parameters p0300 ... p0311 are suitably preassigned for the power unit. The inverter must be in the online mode to "Restore factory setting".
PAGE 22
4.3 Commissioning with the IOP Description Using a text and graphic display, the IOP offers the possibility of selecting Wizards for commissioning, function menus, e.g. for diagnostics or the status display. It has five function keys and a navigation wheel that is simultaneously used as the OK key. The IOP can also be used as handheld terminal. The IOP display goes dark if a key is not pressed within 60 seconds. The display is re-activated if a key is pressed or the navigation wheel is turned.
PAGE 23
Commissioning with the IOP For commissioning, the IOP must either be directly plugged onto the Control Unit of the inverter or must be connected to it via the handheld enclosure. This therefore establishes all of the connections required. Plug the IOP onto the inverter After you have connected-up the Control Unit, locate the lower edge of the IOP, as shown in the diagram, onto the protruding lower section of the Control Unit (①) and snap the IOP (②) onto the Control Unit.
PAGE 24
Note Restoring to the factory setting during commissioning As a first step in the basic commissioning, the Wizard offers "Restore factory setting". This option is always practical if, under certain circumstances, your Control Unit was used in other applications and you are not completely certain which settings were made at the CU. Changing numerical values from the IOP Numerical values are changed digit-by-digit in the IOP.
