Lenze’s EVS9331-ER is engineered as a servo register controller suitable for demanding automation tasks. This device supports a mains voltage range from 320 to 528 volts AC and is designed to operate within a frequency range of 45 to 65 Hz. It is capable of delivering substantial motor power, rated at 55.0 kW when supplied with either 400V or 480V input.

Output currents are impressive, with the controller providing 110.0 A at an 8 kHz frequency for 400 V and 105.0 A for 480 V. Moreover, at a 16 kHz output, the unit delivers 70.0 A at 400 V and 65.0 A at 480 V. For maximum performance requirements, the EVS9331-ER can accommodate peak output currents of 165.0 A at 8 kHz and 105.0 A at 16 kHz. This drive achieves an output power rating of 76.2 kVA at 400 V and 87.8 kVA at 480 V. The mains current at a 400 V connection reaches 96.4 A, reflecting its robust capacity for energy delivery.

With a motor voltage range extending from 0 to the incoming mains voltage, the device has an indicative power loss of 1470 W when operating at 400 V. Additionally, performance is optimized under varying temperatures, with a power reduction of 2% per degree Celsius from 40°C to 55°C, and a 5% reduction per 1000 meters of altitude beyond 1000 meters amsl.

In terms of practical dimensions, the EVS9331-ER controller measures 440 mm in length, 680 mm in width, and 285 mm in height, while its weight is approximately 59 kg. These specifications make the EVS9331-ER a solid choice for projects demanding efficiency, reliability, and adaptability in motor control.
