Commissioning

WARNING

Risk of injury due to unexpected movement of components.
• Protect the positioning range from unwanted intervention.
• Keep foreign objects out of the positioning range.
• Perform commissioning with low dynamic response.

WARNING

Severe, irreversible injuries from accidental movements of the connected
actuator technology.
Unintentional movements of the connected actuator technology can result from
exchanging the connecting cables of a servo drive or between servo drives.
• Before commissioning: All cables must be correctly assigned and connected.

WARNING

Danger of burns from hot housing surfaces.
Metallic housing parts can reach high temperatures during operation.
Contact with metal housing parts can cause burn injuries.
• Do not touch metallic housing parts.
• After the power supply is switched off, let the device cool down to room

temperature.

Commissioning: IO-Link operation
Prerequisite for the IO-Link master/application software

The IO-Link master must support the IO-Link standard "IO-Link BLOB Transfer &
Firmware Update V1.1".

An IODD device description file with version V1.2.6 or higher is used in the
application software.

Preparation
1. Check the mounting of the drive system.
2. Check the wiring of the power supplies and the IO-Link "C/Q" interface at the

[Power] and [Logic] connections.

3. Download and install the application software of the IO-Link master.
4. Download parameter set 

è

 www.festo.com/sp.

Procedure
1. Switch on load voltage.
2. Switch on logic voltage via IO-Link master (switch-on delay ≥50 ms required).
3. Wait for initialisation until C/Q LED is yellow (

L

 7 s).

4. Update parameter set 

è

 10.2 Parameter set.

5. Make the drive system ready for operation

If data backup is performed (Data Storage), the application data is auto-
matically transferred to the integrated drive and must then be permanently
saved 

è

 10.1 Data backup (Data Storage), 8. Save application data

If data backup is not performed (Data Storage), referencing with end-
position determination must be carried out 

è

 10.1 Data backup (Data

Storage), 9. Referencing the new drive system

The drive system is then ready for operation.
10.1

Data backup (Data Storage)

Perform data backup (Data Storage)
The table shows all steps for executing the data storage function using the appli-
cation software of the Festo USB IO-Link Master CDSU-1 as an example.

Steps for executing the data storage function

1. Start the application software

Run app

2. Open the IODD file (device description file)

Variants for opening the file:

Open the "File" tab and execute the "Open IODDs" submenu 

1

Via the automatic search 

2

1)

Via the key combination "Ctrl + o 

3

"

By drag-&-drop 

4

3. Establish a connection to the IO-Link master

Press the "Connect 

1

" button

The connection is established 

2

Default setting: the data storage function is disabled — the "Disable 

3

" button is active

4. Activate automatic saving (backup)

In the "Data Storage" tab press the "Backup/Restore 

1

" button

The predefined application data is automatically saved in the IO-Link master with every change

5. Activate one-time storage (restore only)

In the "Data Storage" tab press the "Restore only 

1

" button

The predefined application data is saved once in the IO-Link master

6. Replace device

Disconnect the electrical connections at the integrated drive

The connection to the IO-Link master is interrupted 

1

Electrically connect the new integrated drive to the IO-Link master

The connection to the IO-Link master is automatically re-established 

2

After a successful compatibility check of the device ID "0x0000.0A ... 0C, DeviceID1 ... ID3 ", the

application data are automatically transferred to the integrated drive
