Emotron FDU 2.0 AC drive

Connect motor cables1. Remove the cable interface plate from the AC drivehousing.2. Put the cables through the glands.3. Strip the cable according to Table 8.4. Connect the stripped cables to the respective motor terminal.5. Put the cable interface plate in place and secure with thefixing screws.6. Tighten the EMC gland with good electrical contact tothe motor and brake chopper cable screens.Placing of motor cablesKeep the motor cables as far away from other cables as possible,especially from control signals. The minimum distancebetween motor cables and control cables is 300 mm.Avoid placing the motor cables in parallel with other cables.The power cables should cross other cables at an angle of90.Long motor cablesIf the connection to the motor is longer than 100 m (forpowers below 7.5 kW please contact Emotron), it is possiblethat capacitive current peaks will cause tripping at overcurrent.Using output coils can prevent this. Contact the supplierfor appropriate coils.Switching in motor cablesSwitching in the motor connections is not advisable. In theevent that it cannot be avoided (e.g. emergency or maintenanceswitches) only switch if the current is zero. If this isnot done, the AC drive can trip as a result of current peaks.3.3 Connection of motor andmains cables for model090 and upAC drive FDU48-090 and up, FDU69-090 andupTo simplify the connection of thick motor and mains cablesto the AC drive, the cable interface plate can be removed.Clamps for screeningCable interfaceMotor cableDC+, DC-, R (optional)Mains cableFig. 25 Connecting motor and mains cables1.
