Description
Product Introduction
The Indramat (Bosch Rexroth) CLM01 is a high-performance positioning control module engineered for complex multi-axis motion control applications. Designed to interface directly with Indramat drive systems—such as the DDS, KDA, and TVM drive series—the CLM01 handles closed-loop position monitoring, speed generation, and high-speed target indexing independent of the main PLC.
Equipped with an integrated front-panel keypad and display (or support for external programming terminals), the CLM01 allows machine operators to input motion profiles, stroke lengths, and dwell times directly. Its modular architecture relies on plug-in firmware EPROM modules, enabling tailored execution for roll feeds, press feeds, cut-to-length systems, and transfer lines without adding burden to upper-level control networks.

Application Scenarios & The “Trench” Experience
When an automated indexing table or high-speed feeder loses position alignment mid-shift, the fault often traces back to a corrupted memory module or failed encoder channel on a central motion card. In our field experience, replacing a faulted CLM01 card on a high-speed stamping line required transferring the socketed firmware EPROM chip directly from the damaged board to the replacement unit. Once re-seated and powered up, the card retained all original program parameters, getting the feed rolls back into sync within 30 minutes without needing a full system re-download.
- Metal Stamping & Press Feeds – Controls high-speed sheet metal indexing and coil feed roll positioning.
- Packaging & Cut-to-Length Lines – Manages continuous motion synchronization and flying shears.
- Gantry & Transfer Systems – Executes precise point-to-point positioning for pick-and-place automation.
- Specialty Machine Tools – Provides dedicated axis motion profiles for grinding, drilling, and indexing heads.

Transparency SOP: Quality Assurance & Testing
Every Indramat CLM01 module undergoes dynamic hardware validation prior to shipment:
- Visual & Header Inspection: Inspecting backplane pin connectors, front-panel keypad membranes, and EPROM socket integrity.
- Power-Up & Boot Diagnostic: Seating the card into a live Indramat rack to verify internal DC bus regulation and successful firmware boot routines.
- Encoder Signal & Motion Loop Verification: Simulating quadrature encoder feedback inputs to verify high-speed counting and position loop closed-loop responses.
- Serial Communication Test: Communicating via RS-232/RS-485 to confirm parameter read/write routines and diagnostic readout functionality.
- ESD Cleaning & Protective Packaging: Cleaning connector pins with isopropyl contact cleaner and sealing the module in anti-static shielding bags with fresh desiccant.
The Veteran’s Tech Trap Guide (Crucial Value-Add)
⚠️ Never Swap Cards Without Moving the Firmware EPROM! The CLM01 board houses operating logic on a removable firmware module (e.g., FWC-CLM01…). Installing a replacement board without transferring your original system’s firmware chip will result in boot errors or incorrect axis profiles.
❗ Check the Back-Up Battery Voltage! The CLM01 uses an onboard lithium battery to preserve volatile RAM parameter memory. If replacing a unit that has been in long-term storage, check or replace the battery before commissioning; otherwise, turning off cabinet power will erase your motion program.
⚠️ Align Pin Headers Carefully During Installation: The backplane connector pins on legacy Indramat rack systems can bend easily if forced. Ensure the card glides smoothly along the card-cage guide rails before applying pressure to seat the connectors.
Frequently Asked Questions (FAQ for Conversion)
Q: Does the CLM01 require external software to program motion profiles?
A: No. Standard motion parameters and positioning blocks can be entered directly using the front panel keypad and display unit, though serial communication software can also be used for backup and editing.
Q: What should I do if the CLM01 display shows a “Clear RAM” or memory error?
A: This typically indicates a depleted internal backup battery or power drop while writing to RAM. Re-enter parameters or restore the program backup after replacing the lithium battery.
Q: Are different sub-models (e.g., CLM01.1 vs CLM01.3) directly interchangeable?
A: Not always. Sub-models differ in hardware revisions, expansion slots, and backplane pinouts. Always match the full part number and firmware designation when sourcing a drop-in replacement.
Q: Does the CLM01 support digital feedback encoders?
A: Yes, depending on the installed interface option cards, the CLM01 supports standard differential RS-422 incremental encoders and absolute encoders.
Q: What warranty is provided on this surplus Indramat module?
A: All CLM01 modules supplied come backed by a full 12-month functional replacement warranty.
