4.2.2. Motor connection / Winding protection
• The electrical connection of the motor and the winding sensors is made by power con nector or by cable
(standard length: 5 m).
• The motor cable must be shielded. Ensure that the cable shield contacts the frame over a large area at both
ends.
• The motor phases U1, V1 and W1 must be connected correctly to the corresponding phases of the inverter;
they must not be interchanged.
• We recommend using a inverter with a switching frequency of 12 kHz.
• The PTC resistor embedded in the winding must be evaluated in an appropriate manner in the control system
or the frequency inverter to protect the motor from overheating.
