Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13458985 (type designation I5CAE0000000VA000S) is a pluggable EtherCAT control unit developed for the Lenze i550 cabinet frequency inverter series within the broader i500 product family. Serving as the processing and communication hub for the inverter power unit, this frequency inverter control module provides real-time motion control and fieldbus connectivity across industrial automation systems. The hardware interface features dual RJ45 fieldbus connectors, an onboard Micro USB-B engineering port, and terminal connections for physical signal interfacing, including five configurable digital inputs, one 24 V DC digital output, two multi-range analog inputs, one analog output, and one changeover relay output.
Integrating a replacement unit requires matching both physical network interfaces and application parameter configurations. Network communication is handled via built-in dual RJ45 EtherCAT interfaces running at 100 Mbit/s and supporting the CiA 402 drive profile in line or tree topologies. Commissioning a replacement unit is simplified by the pluggable i500 memory module system, which stores complete drive parameters and enables direct physical transfer to a replacement unit without software tools or line power. When manual setup or tuning is needed, the unit connects directly to a PC running Lenze EASY Starter commissioning software via the Micro USB-B port, with additional operator interaction supported by optional i500 keypads or WLAN modules. ABC Industrial Parts can assist maintenance teams with donor parameter extraction and ready replacement control units.
System status and network conditions are monitored through front-panel LED indicators, including the RDY status LED, ERR fault LED, LA link and activity LEDs for ports 1 and 2, and combined RUN / ERR EtherCAT indicators. Diagnostics can also be performed electronically by evaluating diagnostic parameters such as 0x2824 and 0x2D00, reading EtherCAT diagnostic objects, or connecting via EASY Starter. Initial troubleshooting should focus on verifying mains power supply, motor wiring, fieldbus shielding, cable integrity, and cooling air flow. When persistent hardware failures or internal faults occur, internal repairs cannot be performed in the field; replacing the control module and sending the faulty unit to ABC Industrial Parts for professional repair is the fastest route to resume production.

Programming and Configuration
Commissioning and configuring the Lenze 13458985 EtherCAT control unit is primarily accomplished through Lenze EASY Starter engineering software. Connection to a setup PC is established directly through the onboard Micro USB-B interface port, eliminating the need for specialized bus converters or powered rack setups during initial configuration.
For rapid device replacement and offline configuration backup, the unit utilizes a pluggable i500 memory module. All operational parameters, motor profiles, and fieldbus node settings stored on the memory card can be moved directly into a replacement control unit, enabling immediate parameter restoration in production environments.
Communication and System Integration
The Lenze 13458985 control unit operates as a real-time fieldbus slave on EtherCAT industrial networks. Equipped with dual RJ45 ports, the unit supports standard 100 Mbit/s transmission speeds and facilitates flexible cabling in line and tree network topologies.
Compliance with the standardized CiA 402 drive profile ensures standardized motor motion control integration into EtherCAT masters. Physical field signal integration is provided through five configurable digital inputs, one 24 V DC digital output, two multi-range analog inputs supporting 0–10 V or 0/4–20 mA, one analog output, and one changeover relay output.
Diagnostics and Status Indication
Visual status monitoring is provided on the front panel by dedicated status LEDs for device readiness (RDY), active faults (ERR), EtherCAT link/activity per network port (LA Port 1 & 2), and fieldbus state machine status (RUN / ERR). Extended diagnostics are accessible by querying diagnostic parameters 0x2824 and 0x2D00, inspecting EtherCAT diagnostic objects through the network master, or establishing a PC connection using Lenze EASY Starter via the Micro USB-B port.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| RDY | Green/Red - Blinking/Solid | Green Blinking: Ready for operation, Green Solid: Inverter active/running, Red Blinking: Error active |
| ERR | Red - Solid/Blinking | Fault indicator indicating active fault condition requiring intervention |
| LA (Link/Activity) Port 1 & 2 | Green - Solid/Blinking | EtherCAT link status and activity per network port (Green Solid: Link present, Green Blinking: Bus traffic active) |
| RUN / ERR (EtherCAT) | Green/Red - Solid/Blinking | EtherCAT state machine indicators (RUN Green: Operational state; ERR Red: EtherCAT communication error) |
Replacement and Spare Part Considerations
When replacing a Lenze 13458985 control unit, verify that the replacement device matches the control type and fieldbus interface required by the application. This control module is specifically designed for attachment to Lenze i550 cabinet frequency inverter power units.
Downtime can be significantly minimized by leveraging the pluggable i500 memory module. Transferring the pluggable memory card from the damaged unit to the replacement module transfers all parameters, fieldbus configurations, and motor profiles without requiring line power or software tools.
If parameter data cannot be read from the original memory module, configuration files must be downloaded using Lenze EASY Starter software over the Micro USB-B interface before putting the replacement drive unit back into active service.
