ware update.
To pre-charge water-cooled 6SR325 drives, set parameters as follows:
• Set parameter Precharge enable (2635) to 'Type 5 Open' or 'Type 6 Closed'.
• Set parameter Cell voltage (2550) to '750 V AP' or '750 V AP 4Q.'
Refer to the Water-cooled Operating Instructions Manual for more information on the 750 V
AP cell.
Incorrect parameter settings
The drive will not work properly if relevant parameters are not set correctly.
Incorrect parameter settings may impair the drive function and cause severe material damage.
Verify changed parameters and ensure that all parameter settings are correct.
