Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 463315 EPL-10201 is a high-performance Drive PLC module designed to add integrated IEC 61131-3 control capabilities directly to Lenze drive systems. Operating on an 18 to 32 V DC supply voltage range with a 24 V DC nominal rating, this plug-in module installs directly into the automation slot of Lenze 8200 vector frequency inverters and Lenze 9300 servo drives. By performing local logic execution and motion control sequences within the drive hardware, the module eliminates the need for separate central PLC hardware and reduces cabinet space in automated packaging, material handling, textile, automotive assembly, and converting lines.
Interfacing the unit with external devices and host automation involves built-in digital I/O and network connections. The module features four 24 V DC fast interrupt-capable digital inputs and two short-circuit protected 24 V DC digital outputs, along with an integrated CAN system bus interface operating at speeds up to 1000 kbit/s using CANopen or Lenze system bus protocol. Replacing an existing unit requires transferring the original application program and device parameters, as a spare controller will not run without programmed logic. Machine programs are transferred using Lenze Drive PLC Developer Studio (DDS) software, where complete program backups or configuration extractions from a donor module can be loaded prior to putting the machine back into service. ABC Industrial Parts can support maintenance teams with replacement hardware to minimize operational downtime.
System diagnostics and operating states are indicated via status LEDs located on the module front, including RUN, FAIL/ERR, and CAN RUN/ERR indicators. Detailed monitoring is also accessible through DDS software or connected operator keypads such as the Keypad XT and Keypad 9300. When errors occur, diagnostic codes such as watchdog timeouts (EPL-001) or CAN bus faults (EPL-003) point directly to execution timing or network issues. If a hardware configuration error (EPL-004) persists after powering down and reseating the module in its drive slot, internal hardware damage is present, requiring replacement or repair through ABC Industrial Parts.

Programming and Configuration
Programming and configuring the Lenze 463315 EPL-10201 Drive PLC is carried out using Lenze Drive PLC Developer Studio (DDS) software. The environment supports standard IEC 61131-3 programming languages, allowing engineers to construct complex motion control sequences, positioning tasks, and process logic that execute directly inside the host drive controller.
The module architecture includes 512 kB of Flash program memory, 512 kB of RAM data memory, and 8 kB of non-volatile NVRAM for retentive data storage. Retentive memory preserves active process parameters, counters, and machine setup data during power cycles. During commissioning or spare part replacement, the user must load the compiled application project into the unit via DDS to re-establish proper machine functionality.
Communication and System Integration
The Lenze 463315 EPL-10201 features an integrated system bus interface based on CAN hardware, capable of supporting communication rates up to 1000 kbit/s. Operating via CANopen or the native Lenze System Bus protocol, this high-speed link provides fast data exchange between drive controllers, external remote I/O, and supervisory automation systems.
By handling time-critical axis positioning and control tasks locally on the drive module, the EPL-10201 significantly decreases the traffic load on higher-level fieldbus networks. Network topology requires proper 120-ohm bus termination resistors at the physical end nodes of the CAN bus line and consistent baud rate selection across all connected nodes for reliable data transmission.
Diagnostics and Status Indication
The EPL-10201 module provides real-time status monitoring through hardware diagnostic LEDs on its front panel alongside comprehensive software diagnostics. Visual indicators display operational states for the PLC core runtime and the CAN system bus connection.
In addition to LED indications, technicians can conduct live troubleshooting using Drive PLC Developer Studio (DDS) software for online variable monitoring and task timing analysis. Diagnostic parameters can also be accessed directly at the machine using a pluggable Lenze Keypad XT or Keypad 9300.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| RUN | Green - Solid / Flashing | Solid Green = PLC program in RUN state; Flashing Green = Stop or initializing state |
| FAIL / ERR | Red - Solid | PLC error, runtime fault, or system error indicating hardware or application failure |
| CAN RUN / ERR | Green / Red - Solid / Flashing | Indicates operational status and error conditions of CAN system bus communication |
Replacement and Spare Part Considerations
When replacing a Lenze 463315 EPL-10201 module, physical installation requires powering down the host inverter and firmly seating the replacement unit into the dedicated automation slot of the Lenze 8200 vector inverter or 9300 servo drive. Inspect the backplane connectors for clean contact prior to fully engaging the module.
A replacement EPL-10201 will not function out of the box without the application software loaded. Maintenance staff must download the specific IEC 61131-3 PLC application program and machine parameter settings using Drive PLC Developer Studio (DDS). Furthermore, verify that the CAN bus node address and baud rate settings match the original drive configuration to restore communication with the rest of the machine.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| EPL-001 | System Watchdog Error | PLC task execution exceeded watchdog timeout limit | Program loop execution too long, task period set too short | Check PLC application program task timing in DDS software and adjust watchdog configuration |
| EPL-002 | Stack Overflow | PLC memory stack exceeded maximum allocated limit | Deep subroutine nesting or excessive local variable declaration | Optimize code structure, reduce recursion and nested subroutines in DDS project |
| EPL-003 | CAN Bus Fault / Bus Off | System bus communication error or physical line disconnect | Bus cabling issue, missing termination resistor, wrong baud rate setting | Verify CAN wiring, check bus termination (120 Ohm) at end nodes, check baud rate settings |
| EPL-004 | Hardware Configuration Error | PLC module lost communication with host drive backplane | Module not seated properly in automation slot, defective module connector, internal hardware failure | Power down, reseat EPL-10201 module in slot. If persistent, replace unit - internal hardware error. |

What do the LED status indicators on the EPL-10201 indicate?
The RUN LED shows PLC program status (solid green for RUN, flashing for Stop), FAIL/ERR indicates system or runtime errors, and CAN RUN/ERR signals CAN bus operational state and communication errors.
How should fault code EPL-004 be resolved during maintenance?
Fault code EPL-004 indicates a communication loss with the drive backplane. First power down and reseat the module in its automation slot; if the fault persists, internal hardware damage is present and the module must be replaced.
