Parameter & program
Parameter set error (checksum / incompatible)
What does it mean?
PR1: checksum error in parameter set 1. PEr: caution — the Lenze setting is loaded automatically. PR0: error in the parameter set.
Common causes
- The parameter set is corrupt or incompatible with the loaded software version (e.g. transferred from a higher-power controller).
How to fix it
- Store the correct parameter set (C0003 = 1) and reload
- for PEr, store the Lenze setting (C0003 = 1)
- send the parameter set to us for analysis if necessary.
After troubleshooting: de-energise the device completely (disconnect the 24 V supply and discharge the DC bus) before opening the covers.
