Lenze 13445950 EPCZEMSD3 8GB Industrial SDHC Memory Card
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13445950 EPCZEMSD3 is an 8 GB industrial SDHC flash memory card engineered for non-volatile application and system data storage in Lenze control and drive environments. Functioning as a high-endurance storage medium within Lenze Controller Accessories, this card retains PLC boot projects, drive parameter sets, application programs, and operational firmware across power cycles. Designed in a standard SD card form factor, the EPCZEMSD3 provides reliable flash storage capable of surviving demanding operating conditions in factory automation, packaging machinery, material handling, and motion control systems.
The EPCZEMSD3 connects directly to the dedicated SD memory card slot on supported host units, including the Lenze c300 Controller, c520 Controller, c550 Controller, Controller 3200 C, and i950 Servo Drive. Engineering project files, boot applications, and firmware updates managed in Lenze EASY Starter or Lenze PLC Designer software can be stored directly onto the card. When commissioned as a backup storage device, the card enables PC-free hardware replacements: maintenance personnel can move the memory card from a failed controller directly to a replacement unit, which automatically loads the saved boot project and drive parameters upon initialization. For critical production lines needing tested spares or assistance with hardware swaps, ABC Industrial Parts supplies verified replacements to ensure fast system recovery.
Diagnostic verification of the Lenze 13445950 memory card is conducted through the host controller's system boot log and status displays within Lenze EASY Starter software. Using an authentic industrial-grade SDHC card instead of commercial consumer media prevents boot failure, file corruption, and host drive faults caused by insufficient write endurance or electrical noise. If a host controller fails to read the card during boot, initial troubleshooting should verify that the memory card is firmly seated in the slot and that the saved project matches the target controller hardware revision. Because internal card controller errors cannot be repaired in the field, replacing the unit or sourcing a tested spare from ABC Industrial Parts is the most reliable method to restore machine operation.

Programming and Configuration
The Lenze 13445950 EPCZEMSD3 memory card works in conjunction with Lenze EASY Starter engineering software and Lenze PLC Designer software suites to manage application programs, parameter files, and system firmware. Engineers can write complete PLC boot projects directly to the card, establishing a reliable non-volatile backup that loads automatically when the host controller boots up.
In addition to project storage, the card enables automated system configuration transfers and PC-free controller parameter backups. During maintenance or hardware migration, transfer of the physical card to a new host unit eliminates the requirement for a local engineering PC, allowing direct parameter restoration and immediate system cloning.
Diagnostics and Status Indication
The Lenze 13445950 EPCZEMSD3 does not feature onboard status LEDs. Diagnostic evaluation is performed at the host level by inspecting the system boot log on the connected controller or drive interface.
Detailed card status verification and file integrity checks can be executed through Lenze EASY Starter commissioning software when connected to the host controller.
Replacement and Spare Part Considerations
Replacing a Lenze 13445950 EPCZEMSD3 memory card requires verifying physical seating and compatibility with the host hardware platform. The card is compatible across Lenze c300, c520, c550, and Controller 3200 C systems, as well as Lenze i950 Servo Drives.
Using standard commercial SD cards as substitutes introduces significant risk of boot project corruption, read/write errors, and drive operational faults due to lower write endurance and lack of industrial noise resistance. Retaining an authentic industrial EPCZEMSD3 card ensures persistent non-volatile parameter storage and rapid recovery during emergency hardware swaps.
Frequently Asked Questions
What is the primary function of the Lenze 13445950 EPCZEMSD3 memory card?
The Lenze 13445950 EPCZEMSD3 is an 8 GB industrial SDHC flash memory card used for non-volatile storage of PLC boot projects, drive parameters, application files, and operational firmware.
Which Lenze controllers and drives are compatible with the EPCZEMSD3 card?
The EPCZEMSD3 memory card is fully compatible with Lenze c300, c520, c550, and Controller 3200 C units, as well as Lenze i950 Servo Drives.
How does the EPCZEMSD3 card simplify hardware replacement during a failure?
Because the card stores the controller's full boot project and parameter set, transferring the card from a failed controller to a replacement unit allows the new hardware to load the saved application automatically without needing an engineering PC.
Which software tools are used to write projects and manage configuration on the EPCZEMSD3?
Project creation, parameter backup, firmware updates, and status verification are performed using Lenze EASY Starter and Lenze PLC Designer software.
Why shouldn't a standard commercial SD card be used as a replacement?
Commercial SD cards lack industrial high-endurance flash architecture and resistance to electrical noise or temperature extremes, which can lead to file corruption, boot failures, and unexpected drive faults.
How can I check the diagnostic status of the Lenze 13445950 memory card?
Card status can be checked by reviewing the host controller's system boot log or by connecting via Lenze EASY Starter commissioning software.
