Lenze EVS9323-EP 9300 position controller

Lenze EVS9323-EP is a 9300 position controller for documented variable-speed drive and positioning functions.

Documented facts

Rebuilt from individual evidence

Concrete system role

Research inference

Unknown: configuration and commercial status

Fact: The Lenze manual lists EVS9323-EP as a 9300 servo position controller 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 servo, or asynchronous standard 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 resolver and encoder feedback options, absolute and relative point-to-point positioning, and touch-probe positioning.

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, the EP controller receives power, motion setpoints, and configured feedback, then regulates the drive axis and its position profile.

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
Controls a variable-speed drive and provides documented speed, torque, and position-control functions for an EP positioning controller.
System position
Acts in the machine control cabinet between the AC or DC-bus supply and the drive axis as part of a 93XX drive system.
Upstream / inputs
Receives three-phase AC or DC-bus power, motion setpoints, and a configured resolver or encoder feedback signal.
Downstream / outputs
Supplies controlled drive output and applies the selected position profile to the machine axis.
Limitations
The controller must be operated only under the conditions in its instructions, with the connected machine and suitable drive selection checked.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • The Lenze manual lists EVS9323-EP as a type and order number in the 9300 servo position-controller range.

    Confidence: high

  • Lenze classifies the EP variant as a 9300 Position Controller servo inverter.

    Confidence: high

  • The 93XX controller is documented for open- and closed-loop control of variable-speed drives with PM synchronous, asynchronous servo, or asynchronous standard motors.

    Confidence: high

    • www.dtc.no — retrieved 2026-09-11; high confidence

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

    Confidence: high

    • www.dtc.no — retrieved 2026-09-11; high confidence

  • The EVS9323 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 resolver feedback and encoder feedback options for the controller.

    Confidence: high

    • www.dtc.no — retrieved 2026-09-11; high confidence

  • The EP function documentation supports absolute and relative point-to-point positioning and touch-probe positioning.

    Confidence: high

    • www.dtc.no — retrieved 2026-09-11; high confidence

  • 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 requires operation under its prescribed conditions and directs adjustment to the connected machine and selection of a suitable motor from the documented table.

Inferences

  • In a machine drive chain, EVS9323-EP receives supply, motion setpoints, and configured feedback, then regulates the motor axis and its position profile.

    Confidence: medium

    Rationale: The manual connects the controller to variable-speed motor control, cabinet installation, supply ratings, feedback systems, and positioning functions; 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-EP in a control cabinet: AC or DC-bus supply, motion setpoints, and resolver or encoder feedback enter the position controller, which sends controlled output to a variable-speed drive axis and position profile.

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

System-position inference: power, motion setpoints, and configured feedback enter EVS9323-EP; controlled output serves the drive axis and its position profile.

Next action

Decision: The captured documentation supports the documented position-controller role and rated context for EVS9323-EP; 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.
