Lenze EVS9322-EP 9300 position controller

Lenze EVS9322-EP is a 9300 position controller; review its supply context, PLC or terminal inputs, drive stage and exact configuration before recovery.

System role

Rebuilt from individual evidence

Evidence-led recovery

The Lenze BA9300POS EN 2.3 operating instructions list EVS9322-EP as a 9300 servo positioning controller and specify a 320-528 V AC, 45-65 Hz mains range with a 460-740 V DC alternative supply for the 9300 types.

The instructions connect automation interface X1 to a superimposed PLC, position control or operating terminal and describe adapting the controller to the mains and drive before entering machine and positioning data.

The rated-data table lists 0.75 kW rated power and 2.5 A at 8 kHz or 1.8 A at 16 kHz for EVS9322-EP under the stated 400/480 V conditions; verify the installed nameplate and configuration before a replacement decision.

System role

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

Function
Controls configured machine positioning as the EP position-controller stage in a Lenze 9300 drive system.
System position
Sits between upstream PLC, position-control or operating-terminal commands and the downstream drive output stage in the machine chain.
Upstream / inputs
Receives the upstream control connection and configured drive, machine and positioning parameters.
Downstream / outputs
Drives the downstream output stage using the position-control sequence documented for the 9300 controller.
Limitations
Unknown: the individual unit's condition, software revision, drive pairing, compatibility and availability are not established by this research.

Evidence ledger

Facts, inferences, and unknowns are kept separate.

Facts

  • The Lenze BA9300POS EN 2.3 operating instructions list EVS9322-EP as a 9300 servo positioning controller type.

    Confidence: high

  • Lenze's official 9300EP documentation page describes the 9300EP as a position controller and provides resources for a standard absolute-positioning configuration.

    Confidence: high

  • The operating instructions specify a 320-528 V AC and 45-65 Hz mains range plus a 460-740 V DC alternative supply for the 9300 types that include EVS9322-EP.

    Confidence: high

  • In the manual's 3 AC 400/480 V, 50/60 Hz rated-data tables, EVS9322-EP is listed with 0.75 kW motor power and rated output current of 2.5 A at 8 kHz and 1.8 A at 16 kHz.

    Confidence: high

  • The operating instructions describe the automation interface X1 for connection to a superimposed PLC, position control or operating terminal, with fieldbus modules also listed for that interface.

    Confidence: high

  • The manual's position-control commissioning sequence includes adapting the controller to the mains and motor, entering machine parameters and positioning data, and controlling the drive.

    Confidence: high

Inferences

  • The documented arrangement places EVS9322-EP between an upstream PLC, position-control or operating-terminal layer and the downstream motor/output stage in a machine.

    Confidence: medium

    Rationale: The official role identifies a position controller, while the manual names the upstream automation connection and a downstream drive-control commissioning sequence.

  • The downstream motor/output stage is the controlled side of this chain, based on the manual's EVS9322-EP U, V, W rated-output table and position-control sequence.

    Confidence: medium

    Rationale: The rated-data table identifies controller output terminals and the commissioning procedure describes controlling the drive after motor and position parameters are entered.

  • For a maintenance decision, the evidence supports checking supply context, motor parameters and positioning data against the exact manual before recommissioning or replacement.

    Confidence: medium

    Rationale: The manual makes supply, motor adaptation and machine-position parameters explicit parts of the controller setup.

Unknowns

  • Unknown: the consulted sources do not establish the current condition of the individual EVS9322-EP unit.

    Confidence: low

    Missing evidence: A current inspection or service record for the specific unit was not captured.

  • Unknown: the consulted sources do not establish the installed software revision, motor pairing, machine parameters or wiring of the individual EVS9322-EP unit.

    Confidence: low

    Missing evidence: The exact unit nameplate, parameter backup and as-installed wiring record were not captured.

  • Unknown: the consulted sources do not establish installation-specific replacement compatibility or current availability.

    Confidence: low

    Missing evidence: No approved machine compatibility record or current commercial source was captured.

Next action

The evidence supports a position-control recovery path: verify the exact EP identifier and supply context, capture the installed drive and machine parameters, and use the matching Lenze instructions before recommissioning.

Unknown: the consulted sources do not establish this unit's current condition, software revision, installed drive pairing, compatibility or availability; obtain the nameplate and configuration record before action.
