00453- means motor stalled / motor rotor locked.
When the encoder is activated (P0400 ≠ 0) F00453 is also activated. The fault message F00453 uses the time delay between the inverter pulses and the regular encoder feedback. The delay time is defined in P2178 (delay time motor stalled) and is 10 ms in the factory setting.
