Lenze E84AYCPMV Profibus Module – 8400 Inverter Series
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AYCPMV is a PROFIBUS DP communication option module engineered for the Lenze Inverter Drives 8400 series, including StateLine, HighLine, and TopLine frequency inverters. Operating as a plug-in fieldbus interface, the module mounts directly into the dedicated communication slot of the host drive. It draws operating power internally from the inverter at 5 V DC and 0.17 A, eliminating the need for external auxiliary power supply wiring. This module enables direct integration of 8400 inverters into centralized PROFIBUS fieldbus networks across automated systems such as material handling, conveyor networks, packaging lines, and automotive manufacturing facilities.
Physical bus connection is established through a standard 9-pin Sub-D female RS-485 connector located on the module front panel. Hardware addressing is configured directly on the device using an integrated 7-pole DIP switch to set the physical PROFIBUS station node address. The module supports both PROFIBUS DP-V0 and DP-V1 protocol extensions with automatic baud rate detection ranging from 9.6 kbit/s up to 12 Mbit/s, enabling rapid network synchronization. When replacing an existing module, matching the 7-pole DIP switch settings ensures seamless fieldbus recognition upon power-up. Parameterization and commissioning can be performed using Lenze EASY Starter or Lenze Engineer configuration software, with support available from ABC Industrial Parts when preparing replacement units.
Real-time network diagnostics are indicated via front-panel LEDs labeled BUS OK and BUS ERR. The green BUS OK LED signals active data exchange, initialization, or bus disconnection, while the red BUS ERR LED indicates fieldbus faults, parameterization errors, or communication timeouts. Diagnostic parameters and fieldbus status can also be accessed through the host inverter using a Keypad X400 terminal or remotely via software tools. Internal electronic or communication board faults are not field-serviceable; replacing a faulty card or securing a tested exchange unit from ABC Industrial Parts provides a direct route to restoring network operation and avoiding extended machine downtime.

Programming and Configuration
Configuration and software integration of the Lenze E84AYCPMV PROFIBUS module are performed using Lenze EASY Starter or Lenze Engineer configuration packages. These software environments facilitate the setup of process data structures and enable cyclic communication mapping between the host inverter and the fieldbus master PLC.
Hardware station addressing is set manually using an integrated 7-pole DIP switch on the module body. Setting the DIP switches to the designated PROFIBUS node address prior to installation ensures that the fieldbus master recognizes the drive immediately upon network initialization without requiring software-based node re-assignment.
Communication and System Integration
The E84AYCPMV connects to PROFIBUS DP networks via a standard 9-pin Sub-D female RS-485 connector. The unit features automatic baud rate detection across transmission speeds from 9.6 kbit/s to 12 Mbit/s, permitting effortless integration into existing bus topologies without manual transmission rate matching.
Support for both PROFIBUS DP-V0 and DP-V1 protocols allows the module to handle deterministic cyclic data exchange for real-time speed and torque control alongside acyclic parameter channels. The DP-V1 acyclic channel enables background parameter read/write access, remote drive diagnostics, and configuration backup while the drive continues real-time motion control.
Diagnostics and Status Indication
Fieldbus operating status is visually displayed on the module front panel using two status LEDs labeled BUS OK and BUS ERR. Additional diagnostic information can be retrieved via the host drive using a Keypad X400 diagnostic module or through connected engineering software tools.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| BUS OK | Green - Solid / Blinking / Off | On: Active data exchange; Blinking: Initializing / ready for data exchange; Off: No connection or bus error. |
| BUS ERR | Red - Solid / Blinking / Off | On: Fieldbus error, timeout, or configuration error; Blinking: Parameterization error; Off: Normal operation / no error. |
Replacement and Spare Part Considerations
When replacing a failed E84AYCPMV module in a Lenze 8400 StateLine, HighLine, or TopLine inverter, verify that the replacement module is completely plugged into the drive's communication slot. Because power is supplied internally at 5 V DC, no auxiliary power cables need to be connected.
Before applying power to the drive, mirror the position of the 7-pole DIP switches from the original module onto the replacement unit to ensure the physical node address matches the PLC configuration. Once power is restored, the module will automatically match the network baud rate and resume cyclic communication with the PROFIBUS master.
Frequently Asked Questions
Which Lenze inverter models support the E84AYCPMV PROFIBUS module?
The E84AYCPMV communication module is designed for direct insertion into Lenze 8400 Inverter Drives, including StateLine, HighLine, and TopLine models.
How is the PROFIBUS station address set on the E84AYCPMV module?
The station node address is set manually using an integrated 7-pole DIP switch located directly on the module prior to connecting the drive to the network.
Does the Lenze E84AYCPMV require external auxiliary power?
No, the module draws power directly from the host 8400 inverter drive's internal power supply at 5 V DC and 0.17 A when installed in the communication slot.
What engineering software is used to configure the E84AYCPMV?
The module can be configured using Lenze EASY Starter or Lenze Engineer software tools, as well as monitored directly using the host drive's Keypad X400.
What do the BUS OK and BUS ERR status LEDs indicate?
The green BUS OK LED indicates active fieldbus communication, initialization, or bus loss. The red BUS ERR LED indicates fieldbus errors, parameterization faults, timeouts, or normal operation when off.
