Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVTCE1524SX0 is a 1.5 kW frequency inverter belonging to the 8400 TopLine C model line within the Inverter Drives 8400 family. Designed for cabinet mounting with an IP20 protection rating, this drive operates on a 3-phase input voltage range from 320 V to 528 V AC. It provides a rated continuous output current of 3.9 A with dynamic overload capacity reaching up to 5.85 A for 60 seconds. Capable of generating output frequencies from 0 to 599 Hz across an output voltage range of 0 to 400 V AC at an 8 kHz switching frequency, it supports dynamic positioning, trajectory generation, and synchronized motion control. The device features integrated Safe Torque Off (STO) functional safety circuitry, eliminating the need for separate external safety relays in compliant machine installations.
For network control and sensor integration, the E84AVTCE1524SX0 comes equipped with an onboard CANopen system bus interface and a 15-pin Sub-D connector that supports universal encoder feedback, including Resolvers, HTL, TTL, SinCos, and SSI absolute encoders. Modular networking is expanded through an integrated MCI extension slot, accommodating option modules such as PROFINET (E84AYCER), PROFIBUS (E84AYCPM), and EtherCAT (E84AYCET). Commissioning a replacement unit is streamlined via the pluggable EAM918 EEPROM memory module, which holds the device parameter set, CAN network IDs, and custom logic. This memory chip can be removed directly from a faulty unit and inserted into a replacement drive for tool-free parameter transfer without requiring software tools. Online parameter backup, commissioning, and drive configuration can also be executed using Lenze EASY Starter or L-force Engineer software. ABC Industrial Parts can support maintenance teams with replacement units and matching hardware accessories to keep production systems operating.
Diagnostic indication is provided on the front panel by dedicated status LEDs covering drive ready, drive busy, and CANopen communication states. Detailed diagnostic messaging and error codes can be reviewed using an optional EZAEBK100 Keypad XT diagnostic tool or through EASY Starter software. When persistent error conditions occur—such as output short circuits (OC1), DC-bus overvoltage (OU), undervoltage (LU), or parameter set corruption (PI)—first-line checks on power wiring, fieldbus cables, and external braking resistors can isolate external faults. Hardware self-test failures, such as internal error H01, point to internal electronic component damage that cannot be serviced on site; in these situations, securing a tested exchange unit or utilizing professional repair services from ABC Industrial Parts provides a direct solution to restore full drive functionality.

Programming and Configuration
Drive setup and parameterization for the Lenze E84AVTCE1524SX0 are performed using Lenze EASY Starter or L-force Engineer software packages. These engineering tools give technicians access to motor parameter settings, trajectory generation, positioning profiles, and internal I/O mapping across the drive's 8 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs. Integrated Safe Torque Off (STO) functional safety parameters are also managed within the system logic to ensure safe shutdown performance without external safety relays.
Parameter management is supported locally through the pluggable Lenze EAM918 EEPROM memory module. Complete device configurations—including control parameters, CAN IDs, and customer-specific motion profiles—are written directly to this module during operation. When substituting a unit during maintenance, transferring the existing EAM918 module into the replacement inverter duplicates the full parameter set without connecting a PC or reloading software project files.
Communication and System Integration
The Lenze 8400 TopLine C inverter features an onboard CANopen system bus interface for system-level networking and axis synchronization. In addition to standard CANopen capabilities, the hardware includes a modular MCI extension slot designed to accept fieldbus communication cards. Supported MCI modules include PROFINET (E84AYCER), PROFIBUS (E84AYCPM), and EtherCAT (E84AYCET), allowing the drive to integrate directly into higher-level PLC architectures such as EtherNet/IP or POWERLINK environments.
Feedback integration is handled via a dedicated 15-pin Sub-D multi-encoder interface connector. This universal feedback interface supports a wide variety of motor feedback devices, including Resolvers, HTL, TTL, SinCos, and SSI absolute encoders. This flexibility enables high-accuracy positioning, dynamic trajectory execution, and multi-axis speed synchronization across diverse packaging, logistics, and material handling machinery.
Diagnostics and Status Indication
The front panel of the E84AVTCE1524SX0 drive includes diagnostic status LEDs that provide visual information regarding operational states and fieldbus activity. Drive status is tracked through the DRV-READY and DRV-BUSY indicators, while fieldbus communications on the CANopen network are reported by the CAN-RUN and CAN-ERR LEDs. System status, active parameters, and error history can also be read directly via the optional EZAEBK100 Keypad XT diagnostic unit or through online diagnostics in EASY Starter.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRV-READY | Green - Solid / Flashing | Green: Drive operational and ready for operation. Flashing Green: Drive active / enabled. |
| DRV-BUSY | Yellow - Solid | Yellow: Parameter transfer or internal process active. |
| CAN-RUN | Green - Solid | Green: CANopen communication state is Operational. |
| CAN-ERR | Red - Solid | Red: CANopen bus error / bus off state. |
Replacement and Spare Part Considerations
When replacing an existing Lenze E84AVTCE1524SX0 drive, physical and functional matching must be verified prior to power-up. Ensure the replacement unit shares the exact model number and rating (1.5 kW, 320–528 V AC input) to match line protection and motor specifications. If an MCI communication module (such as PROFINET, PROFIBUS, or EtherCAT) is installed on the existing drive, it must be transferred to the replacement unit's MCI slot to maintain control system communication.
To avoid manual re-parameterization, remove the pluggable EAM918 EEPROM memory module from the original drive and insert it into the replacement unit. This transfers the configured parameters, network node settings, and internal safety configuration automatically. After powering up the new drive, verify that the STO functional safety terminals are correctly wired and that communication status LEDs indicate normal operation on the system bus.

Frequently Asked Questions
How do I transfer drive parameters to a replacement Lenze E84AVTCE1524SX0?
Parameter sets can be transferred by moving the pluggable EAM918 EEPROM memory module from the original unit directly to the replacement drive. Alternatively, parameters can be uploaded and restored using Lenze EASY Starter or L-force Engineer software.
What feedback options are supported by the multi-encoder interface?
The onboard 15-pin Sub-D multi-encoder connector supports Resolvers, HTL, TTL, SinCos, and SSI absolute encoders.
Which fieldbus interfaces are compatible with the MCI extension slot?
The MCI slot accepts optional fieldbus cards including PROFINET (E84AYCER), PROFIBUS (E84AYCPM), and EtherCAT (E84AYCET), as well as EtherNet/IP and POWERLINK modules.
What does fault code H01 indicate on the 8400 TopLine C drive?
Fault code H01 indicates an internal hardware self-test failure on the control board. If cycling the input power does not clear the error, internal component damage is present, requiring repair or device replacement.
Does the E84AVTCE1524SX0 drive require an external safety relay for STO?
No. The inverter features integrated Safe Torque Off (STO) functional safety circuitry, which satisfies safety shutdown requirements without needing external safety relays.
