Lenze EVS9325-ES 9300 Servo Inverter 5.5 kW

5.5 kW 9300 servo inverter for 400 V supplies

Rated 5.5 kW on 400 V, the Lenze EVS9325-ES is a servo inverter for speed and torque control of servo motors, with a resolver feedback input and freely assignable inputs and outputs. Peak output reaches 19.5 A for the short overload period defined in the manual. On the Lenze website the 9300 appears among the previous products, which makes this a legacy drive. Values are taken from the 9300 servo inverter system manual EDSVS9332S EN 6.0, 07/2013, and supply, hardware and software version should be confirmed before you order.

Technical specifications

Standards and operating conditions

The mains connection is 3/PE AC 320 V to 440 V at 45 to 65 Hz, with an alternative DC supply of 450 V to 620 V. Protection is IP20, or IP41 when the unit is mounted in push-through technique. The motor cable may be less than 50 m at 8 kHz without extra filters. Printed approvals are CE (2006/95/EC and 2004/108/EG) and cULus, File No. E132659.

Reading the type code EVS9325-ES

The manual’s nameplate key reads EVS 93xx, design, version, variant. EVS is the servo controller product range, 9325 is the type number for 5.5 kW at 400 V, E means built-in unit (C would be cold plate) and S means servo inverter. Variants in the key are V003 (cold plate), V004 (Safe Torque Off), V100 (IT mains) and V104 (STO and IT mains); a part number without a V suffix is the standard variant.

Control terminals and feedback options

Per the control data, the controller provides 2 bipolar analog inputs, 2 analog outputs, 5 freely assignable digital inputs, 4 digital outputs and a controller-inhibit input, with 1 ms cycle times. Feedback comes through a 9-pole resolver input, a 500 kHz TTL incremental encoder input, a digital frequency input and a digital frequency output. Fieldbus and serial modules go on the AIF interface (X1). The manual names LECOM-A/B, LECOM-B, LECOM-LI, LON, INTERBUS, INTERBUS Loop, PROFIBUS-DP and DeviceNet/CANopen.

Control accuracy per the manual: the switching frequency is 8 kHz or 16 kHz, digital setpoints are accurate to plus or minus 0.005 Hz, and analog setpoints have a linearity of plus or minus 0.15 percent with an offset of plus or minus 0.1 percent. Cycle times for inputs and outputs are 1 ms. The unit meets the protective measures listed for short circuit, earth fault, overvoltage and motor overtemperature, using a PTC or thermal contact input. These features apply to the 5.5 kW size as to the rest of the range.

Accessory table entries for the 9325 size

Accessory codes in the manual: choke EZN3A0300H013, category C1 filter EZN3B0300H013, chopper EMB9352-E, resistor ERBD047R01k2, push-through kit EJ0038 (cutout 139 x 350 mm); shield kits EZZ0015 and EZZ0016. Above +40 degrees C reduce the rated output current by 2.5% per degree, and by 5% per 1000 m above 1000 m site altitude.
