Warnings and Cautions CAUTION Children and the general public must be prevented from accessing or approaching the equipment! This equipment may only be used for the purpose specified by the manufacturer. Unauthorized modifications and the use of spare parts and accessories that are not sold or recommended by the manufacturer of the equipment can cause fires, electric shocks and injuries.
Installation Command and setpoint sources ot the CU240E The inverter is controlled and monitored per default via terminals. Note The command and setpoint sources can be changed in the commissioning procedure or via Parameters P0700 and P1000. Installing the Control Unit The CU controls the functions of the PM.

Installation Fitting the Control Unit to the Power Module The Control Unit is snapped onto the Power Module as shown in the figure below. To disconnect the CU push the release button on top of the PM. The process of fitting the Control Unit to the Power Module is the same technique independent from the type of G120 control unit or G120 power module.
Installation Terminals Overview of CU240E Terminals The terminals are designed as cage clamps for cable cross sections from 0.2 mm to 1,5 mm (24 … 14 AWG). The different types are listed below: • Digital Inputs (DI) • Digital Outputs (DO) •...
Check List Before power is applied to the inverter/motor system, the following checks should be performed: Check that: ✓ The environmental conditions conform to the inverter/motor specifications The inverter and the motor are securely mounted The inverter and motor are correctly installed with adequate cooling provision The motor and the application/equipment are ready to start, i.e.
Commissioning Description When shipped from the factory the G120 inverter (control unit and power module) must not be operated before a commissioning of the inverter has been performed. This can be done via: ● downloading a valid parameter set from BOP or STARTER ●...
For commissioning the inverter you can use the STARTER software, delivered with the PC Connection Kit or download the latest STARTER software version from the internet under the following link: http://support.automation.siemens.com/WW/view/de/10804985/133100 Create a STARTER Project Commissioning procedure ● Switch the supply voltage to the inverter ●...

Commissioning ● Setting properties of the COM port Via this dialog box, you set the com interface (COM1, COM2, COM3) and the Baud rate (default 38400). To find out the right values, select e.g. COM1 and press the "Read" button. If "???" is displayed in the Baud rate test area select another com interface.

Commissioning ● In this dialog you can enter a name for your inverter - in this case "SINAMICS_G120_CU240E" (no blanks or special characters), then press "Continue" and close the following summary dialog via the "Complete" button. CU240E Getting Started, 10/2007, A5E01301680B AA...
Commissioning Going Online with the Inverter Description With the above described procedure the project is created and the following STARTER dialog appears, but there is still no online connection established so far. To go online with this inverter press . The following dialog box shows in the left column the online and in the right column the offline saved data.
Commissioning Start Commissioning Description With closing the last dialog from the "Going Online Section" the "Offline mode" at the very down in the dialog box changes to "Online mode" and in case of first commissioning the message F00395 appears. It states that no commissioning has been performed so far with the inverter. To confirm, select the message and press the "Acknowledge"...

Commissioning Note Information about the symbols used in STARTER can be found in the online help. Press <shift><F1> and then click at the requested symbol. E.g. If you have confirmed F0395, open the drive unit ( ), double-click the drive object ) and start the wizard for basic commissioning from the following STARTER dialog.
Page 21
Commissioning Now you can select the basic commissioning settings for your application via pull-down menus. With pressing "Continue" button you jump to the next item. In case of "Drive functions" we recommend to select "Identification of all parameters inclusive the saturation curve" as shown in the figure below: CU240E Getting Started, 10/2007, A5E01301680B AA...

Commissioning The basic commissioning wizard ends with the following dialog: To complete basic commissioning, the motor data identification, selected during basic commissioning must be performed via switching on the inverter. This can be done via the chosen command source (e.g. terminals, BOP or communication) or via STARTER as shown in the dialog box below.
Page 24
Commissioning will be displayed. Once Motor data identification has finished, the alarm disappears and the inverter switches OFF ( becomes colored again). CU240E Getting Started, 10/2007, A5E01301680B AA...

Commissioning Commissioning the application Now you can commission your application via the dialog boxes of the drive navigator or via the functions in the navigation area. If you have performed the application commissioning, disconnect your PC from the inverter via .
Commissioning This selection performs in addition to disconnecting the PC form the inverter the following steps: : saves project on your PC : saves drive settings on your PC (Upload) : Saves data from inverter RAM to EEPROM Factory reset Description With a factory reset a defined initial state of all of the inverter parameters can be re- established.
Diagnostics Fault s and alarms A fault indicates a severe unfavorable state of the inverter. If a fault occurs, the inverter is powered down with an OFF2 command and the LED "SF" on the Control Unit is active. Faults must be acknowledged before the inverter can be switched on again. An alarm states that the inverter is ●...
