- Parameterisation via L-force Engineer: Unified software environment for commissioning, diagnostics, and firmware updates
System Architecture & Signal Flow
The E84DEPCE7514C5CNRR operates within the Lenze L-force automation platform. The signal flow is as follows:
- PLC / Motion Controller → Fieldbus command (speed setpoint, enable, direction)
- 8400 PROTEC Inverter → PWM modulation → Motor control output
- Motor Feedback (encoder optional) → Closed-loop speed/torque regulation
- Diagnostics → Status word transmitted back to PLC via fieldbus; accessible via L-force Engineer software
The decentralised topology eliminates the central drive cabinet, distributing intelligence to each drive node and enabling modular machine design with simplified wiring harnesses.

Technical FAQ
Q: Is the E84DEPCE7514C5CNRR compatible with third-party motors?
A: Yes. While optimised for Lenze MF/MH motors, it supports any standard three-phase induction motor within the rated power range via standard IEC connector.
Q: What fieldbus protocol does the suffix “C5” indicate?
A: The “C5” suffix in the Lenze 8400 PROTEC naming convention denotes CANopen communication interface. Confirm your network topology before ordering.
Q: Can this inverter be used in a STO (Safe Torque Off) safety application?
A: The base E84DEPCE7514C5CNRR supports STO via the integrated safety input. Verify SIL/PLe certification requirements with your safety engineer and consult the Lenze 8400 PROTEC safety manual.
Q: What is the minimum order quantity?
A: Single units available. Volume discounts apply for orders of 5+ units. Contact us for project pricing.
Q: Do you provide a warranty?
A: 12-month warranty against manufacturing defects. Extended warranty options available for OEM/system integrator accounts.
