Application Scenarios & Engineering Pain Points
The S72402 is a powerhouse in high-dynamic applications such as packaging machines, robotic pick-and-place, and precision assembly. The most common engineering headache with the S700 series is “Feedback Synchronization.” These drives support a vast array of feedback protocols; if the drive is not correctly configured for the specific resolution and signal type of the motor encoder during the initial startup, you will trigger a “Feedback Fault” (F439) before the motor even moves.
Typical Application Scenarios:
- Packaging Machinery – Form-Fill-Seal Synchronizes high-speed cutting and sealing stations with sub-millisecond precision.
- Robotics – Articulated Arms Controls high-torque joint axes with complex camming profiles.
- Printing & Converting – Web Handling Maintains precise tension and position during high-speed printing roll-to-roll processes.
Case Study: Robotic Cell Recovery A manufacturing client faced a drive failure in a multi-axis palletizing robot. The specific S72402-NANANA-NA-225 unit was discontinued, and a direct replacement required a complex firmware flash to match the older unit’s motion profile. Our team provided a tested surplus drive and used the Kollmorgen “WorkBench” software to clone the drive parameters from the failed unit’s backup. The robot was back to full cycle times within a single shift, avoiding an expensive control system migration.
Troubleshooting Quick Reference
Don’t let a generic “F-Fault” halt your production. Most drive issues on this platform are related to cabling or environmental noise.
| Failure Symptom | Possible Cause | Quick Check Method | Recommended Action |
|---|---|---|---|
| F439 Fault | Encoder/Feedback Error | Inspect feedback cable integrity | Check shield termination at drive |
| F602 Fault | Overvoltage (DC Bus) | Check braking resistor wiring | Verify deceleration ramp settings |
| F119 Fault | Communication Timeout | Check EtherCAT/CANopen bus cable | Verify bus termination (120Ω) |
| No Logic LEDs | Logic Power Failure | Measure 24 V DC at X1 terminals | Check external 24 V power supply |
Engineer’s Note: ❗ Crucial Advice: Pay extreme attention to the shielding. The S700 series is sensitive to high-frequency common-mode noise. Ensure the motor cable shield is terminated 360° to the EMC-bracket on the drive housing, not just with a “pigtail” wire. A pigtail connection is essentially an antenna for noise, which will cause random “Communication Loss” or “Encoder Errors” at high speeds.
