TAC ATV8, IP55 Variable Speed Drives for Asynchronous Motors. -phase. 80/460 V, 50-60 Hz E-60-24 24 May 2004 ATV 8 IP55 drives are specifically designed for pump and fan applications powered by a three-phase supply 80 to 460 V in the power range 8.5 to 75 kw. They are housed inside a dust and damp proof enclosure which contains: - An ATV 8 drive - A line choke - A built in class B EMC filter A slot is provided for installing an additional contactor. The front panel has a hinged cover. For safety reasons, it can only be opened when the switch disconnector is in the OFF position. The underside of the enclosure should be fitted with cable glands via which the cables can be routed. Options Common functions of the ATV 8: - Powersuite software workshop (for further information about accessories and their relations, please refer to Schneider Altivar Catalogue) - Specific options for an IP 65 enclosure for the remote operator terminal.

() These power levels are for a maximum switching frequency of 2 or 4 khz, depending on the rating, and continuous operation. Switching frequencies are detailed in the section on Technical Specifications. Using the ATV 8ED with a higher switching frequency: For continuous operation derate by one power rating, for example: TAC ATV8ED28N4 for 8,5 kw - TAC ATV8ED46N4 for 0 kw. If no power derating is applied, do not exceed the following operating conditions: Cumulative running time 6 s maximum per 60 s cycle (load factor 60%). (2) For 60 seconds.

CHARACTERISTICS SPECIAL USES Torque characteristics Variable torque applications: Available overtorque: Variable torque applications: 0% of the nominal motor torque for 60 seconds. T/Tn. 0.95 2 2 4 Continuous operation 0.5 For self-cooled motors, cooling is linked to the motor speed. Derating therefore occurs at speeds of less than half the nominal speed. Overspeed operation As the voltage can no longer change with the frequency, induction in the motor is reduced which results in a reduction in torque. Check with the manufacturer that the motor can operate at overspeed. 0 N (Hz) 5 25 50 75 00 0 60 90 20 Self-cooled motor: continuous useful torque () 2 Force-cooled motor: continuous useful torque Transient overtorque.7 to 2 Tn 4 Torque in overspeed at constant power (2) Note: With a special motor, the nominal and maximum frequencies can be adjusted between 0 and 500 Hz using the operator terminal or PowerSuite tools. Switching the motor at the drive output The drive can be switched when locked or unlocked. If the drive is switched onthe-fly (drive unlocked), the motor is controlled and accelerates until it reaches the reference speed smoothly following the acceleration ramp. KM 0 N t t2 t t This use requires configuration of automatic catching a spinning load ( catch on the fly ) and activation of the function which manages the presence of a downstream contactor. t: deceleration without ramp t2: acceleration with ramp Example: breaking of downstream contactor Typical applications: breaking safety circuit at drive outputs, bypass function, switching of motors connected in parallel.
