Nettet7. aug. 2024 · Figure 8: Encoder slips on the shaft between points A and B when the motor switches directions. Part II: Encoder Issues during Startup Incorrect Encoder Channel Phasing. After an encoder offset position learn has been performed, if the motor does not turn and draws a high current, then the encoder phasing may need to be … Nettet28. okt. 2024 · First, to reduce excessive voltages at the motor terminals, look at cable length, specifications, and installation methods. If the cables are in excess of 50m per phase (from drive output terminals to motor terminals), it is likely that using a drive output filter would be of help. There are a handful of different filter types available, but ...
