The available evidence does not establish the Lenze EVS9325-CKV003 as a direct replacement for the EVS9325-EP. The suffixes identify different functions, and the CKV unit also has a different cooling configuration.

Replacement decision

Do not substitute the EVS9325-CKV003 solely because the base model is EVS9325. Confirm both the required application function and the installed cooling arrangement before selecting a replacement.

Model or suffix Confirmed function Confirmed hardware detail Replacement implication
EVS9325-EP Positioner Not stated The replacement must provide the required positioning function.
EVS9325-CKV003 Cam function Cold-plate version without a heatsink Functional and cooling differences prevent assuming drop-in compatibility.
ES and EK variants Not stated Not stated Firmware conversion with EP is possible only through Lenze service.

Function and cooling must both match

The EP suffix identifies a positioner, while CKV identifies a cam variant. The evidence does not show that the CKV application function can replace the EP positioning function.

The CKV unit is a cold-plate version supplied without a heatsink. Its suitability therefore also depends on whether the machine provides the required cold-plate installation. No thermal ratings or mounting requirements are available in the evidence, so verify those requirements with Lenze before installation.

Firmware conversion has a restricted scope

Firmware can be changed among EP, ES, and EK variants, but the procedure requires a Lenze service visit because the necessary adapter is reserved for Lenze internal use. The evidence does not state that this conversion path includes CKV variants; do not treat CKV003 as firmware-convertible to EP without written confirmation from Lenze.

Verification before substitution

  1. Confirm that the original EVS9325-EP is used as a positioner and document the functions the machine requires.
  2. Inspect the installation to determine whether it supports a cold-plate unit without an integral heatsink.
  3. Ask Lenze service whether EVS9325-CKV003 can provide the required EP function and whether any supported conversion exists.
  4. If considering an EP, ES, or EK firmware conversion, arrange it through Lenze service; the required adapter is not available for external use.

FAQ

Can EVS9325-CKV003 directly replace EVS9325-EP?

Direct compatibility is not established. EVS9325-EP is a positioner, while EVS9325-CKV003 is a cam-function, cold-plate unit without a heatsink.

Can Lenze change EVS9325 firmware from EP to ES or EK?

Yes. Firmware changes among EP, ES, and EK require Lenze service and a special adapter unavailable for external use.

Does the EVS9325-CKV003 include a heatsink?

No. The evidence identifies it as a cold-plate version without a heatsink, so verify that the machine provides a suitable cooling installation.
