Product Introduction
Motion control systems live or die by their timing, and trying to run four axes of complex interpolation on a single CPU is a recipe for jitter. The INDEL AG INFO-4KP-94161 solves this by acting as a dedicated peripheral node that handles the dirty work of signal conversion and axis management. It takes the heavy lifting off your INFOMaster, converting raw encoder increments into meaningful units like degrees or millimeters with single-increment precision.
I’ve seen generic motion cards fail when the master controller gets bogged down by HMI updates or network traffic. The INDEL AG INFO-4KP-94161 doesn’t care; it’s a pure hardware node that just executes. It supports servos, VFDs, and even handwheels directly, with onboard DC/DC converters for resolvers and proximity switches. Just remember: this board is dumb on its own. It needs an INFO-PPC host to feed it the control algorithms. Don’t expect it to run standalone logic.
Quality SOP & Tech Pitfalls
The Lab Report:
We don’t guess if it works. Every INDEL AG INFO-4KP-94161 gets a visual inspection for cold solder joints or cracked connectors. Then it goes on our INFO-PPC test rack to verify all four channels can actually lock onto a reference and hold position. We check the onboard DC/DC converters for resolver excitation voltage stability and verify fieldbus communication under load. Finally, it’s sealed in anti-static packaging with a QC tag.
The Engineer’s Warning:
Here’s the trap: this is a peripheral board, not a standalone controller. I’ve seen techs rack up an INDEL AG INFO-4KP-94161 and wonder why it does nothing. It has no brain; the brain is in the INFOMaster firmware on the INFO-PPC host. If your host firmware is mismatched or corrupted, this card is just expensive silicon. Also, check your resolver wiring. The onboard DC/DC converter is robust, but a shorted resolver coil will fry it fast.
Installation & Configuration Guide
- Pre-Installation: ⚠️ Power down the INFO-PPC host and discharge capacitors. Take a photo of the fieldbus termination settings and axis wiring. Verify your INFOMaster firmware version matches the INFO-4KP-94161 hardware revision.
- Removal: Label all 4 axis cables and handwheel connections. Release the DIN clips or ejector screws. Pull the module straight out; do not pry. Inspect the backplane connector for bent pins.
- Installation: Verify the fieldbus node address matches the old module exactly. Slide the INDEL AG into the slot and lock it down. Reconnect axis cables, ensuring resolver and feedback wires are separated from power lines to prevent noise.
- Power-On & Testing: Restore power to the INFO-PPC host. Watch the host diagnostics for node recognition. Verify all 4 axes report “Ready” status. Run a single-axis reference move to confirm the increment-to-mm conversion is correct before enabling full motion.

Frequently Asked Questions
Can I use this card without an INFO-PPC host?
No. The INDEL AG is a pure peripheral node. All control algorithms, interpolation, and trajectory planning run on the INFO-PPC host firmware. This card only handles I/O, signal conversion, and drive interfacing.
Why is my axis drifting after replacement?
Check your resolver wiring and excitation voltage. The INDEL AG has onboard DC/DC converters for resolvers; if the resolver is wired backwards or shorted, you’ll get noisy feedback. Also, verify the “increments per revolution” parameter in the INFOMaster config matches your actual encoder.
Does this support handwheels directly?
Yes. The INDEL AG can read handwheels directly for manual jogging or teach-mode operations. Just ensure your INFOMaster firmware has the handwheel function blocks enabled for that specific axis.
How many of these can I put on one host?
The INFO-PPC host can handle up to 64 axes total. Since the INDEL AG handles 4 axes each, you could theoretically run 16 of these cards on a single host, provided your fieldbus bandwidth and scan time can handle the load.
Is this card obsolete?
INDEL AG still supports the INFO-4KP series, but always verify your specific revision against the latest INFOMaster firmware release notes. Older hardware revisions sometimes require specific firmware patches for new features.
