The Lenze EVS9331-EK is engineered as a servo cam controller optimized for a diverse operating environment. It can manipulate an input voltage range spanning from 320V to 528V AC, coupled with an operational frequency between 45 and 65 Hz. This advanced controller also accepts a DC supply voltage that lies between 460V and 740V, showcasing its capability for high-performance applications.
Rated for a motor power of 55 kW, equivalent to 73.5 HP, this unit effectively operates at both 400V and 480V settings. In terms of output performance, the EVS9331-EK delivers a power rating of 76.2 kVA, while the maximum output current can reach 165 A. For stable operation, the standstill currents are specified at 110 A for an 8 kHz frequency and 70 A for 16 kHz. Users can select either of the switching frequencies to match their application needs.
An overcurrent capacity feature permits 1-minute temporary overcurrent conditions while under base load, enhancing performance resilience. With a reported power loss of 1470 W, the efficiency of the system remains considerable. The motor voltage can soar up to three times the input voltage, accommodating various motor configurations.
Designed with a mains filter current rated at 125 A, the EVS9331-EK supports the integration of RFI filters to mitigate interference in sensitive environments. Weighing in at 59 kg, this servo cam controller is built to endure demanding conditions, making it suitable for a range of industrial applications.
