Lenze EVS9326-ES 9300 Servo Inverter 11 kW

9300 servo inverter, 11 kW

The Lenze EVS9326-ES is the 11 kW (15 hp) servo inverter of the Lenze 9300 series, a servo inverter in the 9300 family, covering speed and torque control with resolver, incremental encoder and frequency inputs. Rated output current is 23.5 A at the 8 kHz setting. 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

General data and approvals

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 EVS9326-ES

Per the key, EVS marks the servo controller range and 9326 the 11 kW size on 400 V. The letter E is the built-in design, and S the servo inverter version. Suffixes would add a variant: V003 cold plate, V004 Safe Torque Off, V100 IT mains, V104 STO with IT mains.

Inputs, outputs and feedback

The manual lists two bipolar analog inputs and outputs, five freely assignable digital inputs, four digital outputs and a separate controller inhibit, all scanned every millisecond. Position and speed feedback enter through the resolver socket, an incremental encoder input at 500 kHz TTL and a frequency input, and a frequency output is available too. The AIF slot at X1 takes the communication modules the manual lists: LECOM-A/B, LECOM-B, LECOM-LI, LON, INTERBUS, INTERBUS Loop, PROFIBUS-DP and DeviceNet/CANopen.

The manual’s operating conditions give climatic class 3K3 for operation, 1K3 for storage and 2K3 for transport, pollution degree 2 and overvoltage category III below 2000 m. The motor thermal sensor is connected through a dedicated input for PTC or thermal contact, and the setpoint inputs offer a signal level of 5 V or 10 V. Together with a rated current of 23.5 A at 8 kHz these data define the use of the 11 kW size.

Accessory table entries for the 9326 size

For this size Lenze lists mains choke ELN3-0150H024-001, C1 mains filter EZN3B0150H024, brake chopper EMB9352-E, brake resistor ERBD047R01k2 and push-through kit EJ0038 with a cutout of 139 x 350 mm, plus shield kits EZZ0015 for the control cable and EZZ0016 for the motor cable. Derate the current by 2.5% per degree above +40 degrees C and by 5% for each 1000 m above 1000 m.
