The Lenze EVS9328-EK is classified as a servo cam controller specialized for automated processes. It has a substantial weight of 12.5 kg. This controller is capable of handling mains voltage between 320V and 528V AC, with frequency compatibility ranging from 45Hz to 65Hz. The design supports motor voltages up to three times the input supply, offering significant flexibility in motor integration.
Under standard operational conditions, the motor power capacity is rated at 22.0 kW, equivalent to approximately 30.0 hp when running at 400V AC. The unit can provide a continuous output current of 30.6 A at a frequency of 16 kHz, while at 8 kHz, the continuous current rises to 47.0 A. Maximum output current at this same frequency can reach 70.5 A, validating its application in demanding environments. For peak conditions at 16 kHz, the output current can be as high as 45.9 A. The controller also experiences a continuous stall current of 47.0 A during 8 kHz operation and maintains a stall current of 30.6 A during 16 kHz operation.
A thermal consideration must be noted as well: the unit's derating factor is set at 2.5% for each degree Celsius exceeding a temperature of 40°C. This recalibration will aid in maintaining stable operation in elevated temperature conditions. Additionally, the operational power loss is quantified at 640 W, which must be addressed in system designs for effective thermal management. Overall, the EVS9328-EK controller’s detailed specifications make it suitable for sophisticated servo control applications.
