If a cable longer than that recommended is used, the filters may overheat. Motor chokes Motor chokes, also known as load reactors can be inserted between the Altivar 32 drive and the motor to: Reduce the peak voltage in the motor and motor cable Limit dv/dt at motor terminals (500 to 1500 V/s) for cables exceeding 164 ft. (50 m) Filter interference caused by opening of a contactor placed between the filter and the motor Reduce the motor ground leakage current and lower the chance of nuisance ground fault trips Smooth the motor current wave form to reduce motor noise 25 Motor Cable Installation Guidelines in Cable Trays or One Conduit This information for the 230 Vac / 480 Vac Altivar 32 AC drives applies to products rated 5 HP and below operating at 4 kHz switching frequency. These guidelines are for the installation of the output power conductors for AC drive and motor installation where up to three un-shielded motor power cables are in one conduit or cable tray and cable lengths are up to 500 feet in length and inverter duty motors compliant to NEMA MG-1 Part 31 are specified. This type of installation is typical for baggage conveyance applications. Number of conductors: Use four conductors for each motor, one per phase and one ground wire for each motor. Cable type: Do not use mineral-impregnated cables. These cables increases likelihood of capacitive coupling between sets of motor cables. Cable installation: Do not install more than three sets of motor power cables (four wires per set) per conduit or cable tray. Install the cables in a dry location as wet cables increase the likelihood of capacitive coupling between sets of motor cables. Cable length: The following table shows the recommended cable length with and without filters using un-shielded cable. Altivar 32: 0.5 - 5 HP rating, installed with un-shielded cable. Maximum of 3 sets of motor power cables per conduit or cable tray Cable length: ft (m) Filter requirements Up to 300 (91) no filter required 300 (91) to 500 (152) dv/dt filter recommended M1 3 ATV32H ppppp Motor choke Accessories & Options
