Fundamental safety instructions

1.1

General safety instructions

WARNING

Risk of death if the safety instructions and remaining risks are not carefully observed

WARNING

Danger to life or malfunctions of the machine as a result of incorrect or changed parameterization

If the safety instructions and residual risks are not observed in the associated hardware documentation, accidents involving severe injuries or death can occur.

• Observe the safety instructions given in the hardware documentation.

• Consider the residual risks for the risk evaluation.

As a result of incorrect or changed parameterization, machines can malfunction, which in turn can lead to injuries or death.

• Protect the parameterization (parameter assignments) against unauthorized access.

• Respond to possible malfunctions by applying suitable measures (e.g. EMERGENCY

STOP or EMERGENCY OFF).

the inverter.

To transfer the OSS license terms from the inverter to a PC, proceed as follows:

1. Switch off the inverter power supply.

2. Insert an empty memory card into the card slot of the inverter. Also see Section:Overview of the interfaces (Page 8)

3. Switch on the inverter power supply.

4. When you have switched on the power supply, wait 30 seconds.

During this time, the inverter writes the "Read_OSS.ZIP" file onto the memory card.

5. Switch off the inverter power supply.

6. Remove the card from the inverter.

7. Use a card reader and load the file to a PC.

3.3 Terminal blocks

Connection of the optional 24 V supply has the following advantages:

● The Control Unit remains in operation after disconnection of the Power Module from the

line supply. The Control Unit thus maintains the fieldbus communication, for example.

● You can use terminals 51 … 54 as digital outputs.

Use a power supply that provides an output voltage in accordance with SELV (Safety Extra Low Voltage) or PELV (Protective Extra Low Voltage).

If you use a common external power supply for terminals 31, 32 and the digital inputs, you must connect GND to GND IN.

In order that you do not have to successively change terminal for terminal, several terminals can be jointly set using default settings ("p0015 Macro drive unit").

The factory settings of the terminals for USS/CANopen and PROFIBUS/PROFINET described above correspond to the following default settings:

● p0015 = 12 (setting in STARTER: "Standard I/O with analog setpoint")

● p0015 = 7 (setting in STARTER: "Fieldbus with data set switchover")

Further default settings can be found in the Operating Instructions, see also: Manuals for the Control Unit (http://support.automation.siemens.com/WW/view/en/30563628/133300).

4.1 Commissioning with STARTER

Proceed as follows to load the configured data into the drive:

1. Select your project and go online:

2. STARTER compares your configuration with the real inverter. STARTER signals any differences in the "Online/offline comparison".

Acknowledge the message by pressing the "Load HW configuration to PG" button.

3. Open "Drive Navigator".

4. Select the "Commissioning" button.

5. Click on "Load data to the drive".

6. ☑ In the screen form, select "After loading copy RAM to ROM".

7. Load your configuration into the inverter.

8. Close the "Commissioning" screen form.

You have loaded your configuration into the drive and therefore performed the basic commissioning.

● In the basic commissioning, you have selected the motor identification (MOT ID). In this case, after the basic commissioning has been completed, the inverter issues the alarm A07991.

● The motor has cooled down to the ambient temperature.

If the motor is too hot, the motor data identification will provide incorrect values and the vector control will become unstable.

Switching on the motor for identification purposes may result in hazardous machine movements.

Secure dangerous machine parts before starting motor data identification:

• Before switching on, check that no parts are loose on the machine or can be spun out.

• Before switching on, ensure that nobody is working on the machine or located within its

working area.

• Secure the machine's work area against unintended access.

• Lower hanging/suspended loads to the floor.
