What F7447 means
Load gear: Position tracking, maximum actual value exceeded p. 292
Common causes
- When the position tracking of the load gear is configured, the drive/encoder (motor encoder) identifies a maximum possible absolute position actual that can no longer be represented within 32 bits. Maximum value: encoder resolution (2^20 or 2^21) * p29244 p. 292
What to do
- Reduce the multi-turn resolution (p29244). p. 292
Before you service the product, read the safety instructions in the manual p. 2.
