7.26 Extended service mode for CU310-2 connected to blocksize power
units
7.26.1

Overview

With the Essential Service Mode (ESM), a drive can still be operated for as long as possible,
even if faults occur.
Only use this function in exceptional situations, where undesirable converter shutdown could
cause significant subsequent damage!
Example
through escape routes by extracting smoke and associated gases. In a case such as this, it
is justifiable that the converter continues to operate in the essential service mode.
Note
Warranty is lost in the essential service mode
If you activate the essential service mode, all of the warranty claims associated with the
converter become null and void. The essential service mode can have the following effects:
• Exceptionally high temperatures inside and outside the converter
• Open fire inside and outside the converter
• Emission of light, noise, particles or gases
The drive logs the essential service mode, and the faults that occur while in essential service
mode in a password-protected memory. This data is only accessible for the service and
repair organization.
Requirements:
The following preconditions are necessary when using ESM with SINAMICS S120:
● CU310-2 PN or CU310-2 DP
● Vector control
