Lenze EVS9323-ES 9300 standard servo inverter

Lenze EVS9323-ES is a 9300 standard servo inverter for documented open- and closed-loop variable-speed drive control.

Documented facts

Rebuilt from individual evidence

Concrete system role

Research inference

Unknown: configuration and commercial status

Fact: The Lenze manual lists EVS9323-ES as a 9300 standard servo inverter and places it in the machine control cabinet.

Fact: The controller is documented for open- and closed-loop control of variable-speed drives with PM synchronous, asynchronous standard, or asynchronous servo drive units.

Fact: The rated data lists 1.5 kW drive power, 3.9 A output current at 8 kHz, 2.9 A at 16 kHz, 320-528 V AC mains, and 460-740 V DC alternative supply.

Fact: The manual documents analog and digital setpoint interfaces, resolver and encoder inputs, and 8 kHz or 16 kHz switching operation.

Fact: The installation data lists EVS9323-ES dimensions and mounting set EJ0037 for thermally separated push-through mounting.

Fact: Lenze's C0086 table lists selection code 112 with MDSKS71-13-150 Servo-S, 1.6 kW, 150 Hz for the 9323 variants.

Inference: In a machine control chain, this controller receives power, motion setpoints, and configured feedback in the control cabinet, then regulates the variable-speed drive output.

Unknown: The installed drive and feedback pairing, option modules, firmware, application fit, lifecycle status, and current availability are not established by the captured sources.

System role

This section explains what the product does and where it acts in the surrounding system.

Function
Regulates a variable-speed drive in open- or closed-loop operation through the documented standard-servo control functions.
System position
Acts vertically in the machine control cabinet between the AC or DC-bus supply and the drive axis as part of a 9300 drive system.
Upstream / inputs
Receives three-phase AC or DC-bus power, analog or digital motion setpoints, and a configured resolver or encoder signal.
Downstream / outputs
Supplies controlled output to the variable-speed machine drive under the configured control loop.
Limitations
The controller is an industrial machine component, not a complete machine, and must be operated under the conditions in its instructions.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • The Lenze manual lists EVS9323-ES as a type and order number in the 9300 standard-servo range.

    Confidence: high

  • Lenze classifies the ES variant as a 9300 Standard Servo servo inverter.

    Confidence: high

  • The 9300 servo controller is documented for open- and closed-loop control of variable-speed drives with PM synchronous, asynchronous standard, or asynchronous servo motors.

    Confidence: high

  • The manual places the controller as an electrical component installed vertically in a machine control cabinet or similar enclosed operating housing.

    Confidence: high

  • The EVS9323 standard-servo rated-data row documents 320-528 V AC mains, 460-740 V DC alternative supply, 1.5 kW motor power, 3.9 A output current at 8 kHz, and 2.9 A at 16 kHz.

    Confidence: high

  • The manual documents analog and digital setpoint interfaces, resolver and encoder inputs, and 8 kHz or 16 kHz switching operation for the 9300 controller.

    Confidence: high

  • The installation data lists EVS9323-ES dimensions and mounting set EJ0037 for thermally separated push-through mounting.

    Confidence: high

  • Lenze's C0086 table groups device 9323 ES/EP with selection code 112 and MDSKS71-13-150 Servo-S Y, 1.6 kW, 150 Hz.

    Confidence: high

  • The manual limits the controller to industrial machine-component use under the conditions specified in its instructions and does not define it as a complete machine.

    Confidence: high

Inferences

  • In a machine drive chain, EVS9323-ES receives supply, motion setpoints, and configured feedback in the control cabinet, then regulates the variable-speed motor output.

    Confidence: medium

    Rationale: The manual connects the controller to variable-speed motor control, cabinet installation, power ratings, setpoint interfaces, and feedback inputs; the chain description combines those documented roles.

Unknowns

  • Unknown: the installed motor and feedback pairing, option modules, firmware, application fit, lifecycle status, and current availability for this specific unit.

    Confidence: low

    Missing evidence: No current unit nameplate, configuration export, option list, firmware record, or authoritative current lifecycle and availability record was captured.

System position diagram

Block diagram of EVS9323-ES in a control cabinet: AC or DC-bus supply, analog or digital motion setpoints, and resolver or encoder feedback enter the standard servo inverter, which sends controlled output to a variable-speed drive axis.

Reading limit: system position only, not a wiring or safety drawing.

System-position inference: power, setpoints, and configured feedback enter EVS9323-ES; controlled inverter output serves the variable-speed drive axis.

Next action

Decision: The captured documentation supports the documented standard-servo inverter role and rated context for EVS9323-ES; this record is not a commissioning or compatibility approval.

Unknown: the installed configuration and current commercial status are not established; capture the complete nameplate and match the exact drive, feedback, option, and revision documentation before replacement or commissioning.
