When replacing a Lenze EVS9329 drive, checking the model number alone may not be enough. The firmware version can also affect compatibility, particularly when the drive is used with Profibus or a specific machine configuration.
For example, the original machine may use an EVS9329 with firmware V8.0, while the available replacement unit has firmware V6.2.
Can the V6.2 unit be used as a replacement?
The answer depends on the functions and parameters required by the machine.
What Should Be Checked?
Before installing the replacement drive, compare the original V8.0 configuration with the functions supported by V6.2.
Pay particular attention to:
- Profibus configuration
- I/O settings
- Motor parameters
- Encoder and feedback settings
- Control configuration
- Application-specific functions and codes
A firmware difference does not automatically mean that the replacement drive cannot work. However, compatibility should be checked before downloading the original parameters and running the machine.
Recommended Checking Procedure
1. Back Up the Replacement Drive
Before making any changes, save the existing parameters of the V6.2 drive.
2. Open the Original Parameter File
Use Lenze GDC (Global Drive Control) to open the parameter file from the original V8.0 drive.
If a firmware-version warning appears, the file can still be reviewed for comparison, but it should not be downloaded directly to the replacement drive without checking compatibility.
3. Compare the Important Parameters
Check whether the Profibus settings, I/O configuration, motor data, encoder settings and control functions used by the original machine are supported by V6.2.
4. Check for Version-Specific Functions
Some functions or codes used in a later firmware version may not be available in an earlier version.
If the machine relies on a function that V6.2 does not support, a drive with a compatible firmware version may be required.
What Information Should You Check Before Ordering?
When sourcing a replacement for an older Lenze drive, we recommend checking:
- Complete model number
- Firmware version
- Hardware version
- Communication interface
- Installed option modules
- Photos of the original nameplate
For discontinued industrial automation products, these details can be important in avoiding compatibility problems.
