Lenze 13445379 ECSEP004C4B ECS Positioning Axis Module Servo Drive
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13445379 ECSEP004C4B is a positioning axis module servo drive from the Lenze ECS Servo System. It controls a positioning axis within a modular multi-axis machine architecture using a shared DC bus and CAN system bus. The drive provides 2 A rated output current and 4 A peak output current, with a nominal 565 V DC bus supplied through a compatible ECS power supply module. Resolver and encoder feedback connections support motor feedback through a 9-pin Sub-D interface or a 15-pin Sub-D interface for Hiperface, Sin/Cos and incremental encoder types.
For replacement commissioning, the ECSEP004C4B uses internal non-volatile EEPROM to retain one parameter set. Parameters can be backed up and restored with Lenze Global Drive Control software using a compatible PC system-bus adapter. Before installing a spare, the replacement must match the existing hardware revision, firmware generation and Pos application variant. The CANopen system-bus connection and any optional PROFIBUS-DP communication through the Lenze EMF2133IB module must also correspond to the installed ECS system.
The ECSEP004C4B provides drive-ready and fault indication through green and red LED states, while the CAN status LED indicates CAN system-bus Run and Error conditions. Global Drive Control can be used for parameter-buffer inspection and diagnostic-history review, and the Lenze Keypad XT provides an additional diagnostic method. During troubleshooting, check the ECS power-supply arrangement, CAN system-bus connection, feedback interface and stored parameter configuration before commissioning a replacement module.

Programming and Configuration
Lenze Global Drive Control is used to inspect the parameter buffer and back up or restore the ECSEP004C4B configuration. A compatible PC system-bus adapter provides the connection for parameter work on the drive.
The drive stores one parameter set in internal non-volatile EEPROM. When transferring the configuration to a replacement, check the hardware revision, firmware generation and Pos application variant so that the spare matches the existing ECS installation.
Communication and System Integration
The ECSEP004C4B uses a CAN bus interface via a pluggable terminal block and communicates over the CANopen system bus. This supports coordinated communication and control between axes in a modular Lenze ECS multi-axis system using a shared DC bus.
Motor feedback is connected through a 9-pin Sub-D resolver interface or a 15-pin Sub-D encoder interface. The encoder interface supports Hiperface, Sin/Cos and incremental encoder types. PROFIBUS-DP communication can be provided through the optional Lenze EMF2133IB communication module.
Diagnostics and Status Indication
The DRIVE READY / FAULT indicator displays the operational state, ready status or active fault condition through green and red LED states. The CAN status LED indicates CAN system-bus communication status, including Run and Error conditions.
Diagnostic work can include parameter-buffer inspection with Lenze Global Drive Control, review of the diagnostic history log, monitoring of drive status and CAN communication, and use of the Lenze Keypad XT. These checks help separate configuration, feedback and CAN system-bus issues during replacement commissioning.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY / FAULT | Green/red | Displays the operational state, ready status or active fault condition through green and red LED states |
| CAN status LED | Indicates CAN system-bus communication status, including Run and Error conditions |
Replacement and Spare Part Considerations
The Lenze 13445379 ECSEP004C4B is a discontinued positioning axis module servo drive for legacy ECS Servo System equipment. Replacement compatibility depends on the existing ECS power supply module, hardware revision, firmware generation and Pos application variant.
The internal EEPROM allows one parameter set to be backed up and restored through Lenze Global Drive Control. Before returning a spare to service, confirm the CANopen system-bus connection, feedback interface, optional EMF2133IB communication module and transferred parameter configuration against the installed machine.
