can send "funny" signals that make the servo behave erratically and hit its limits. Faulty Control Module

(short-circuit protection) in the power section has triggered, often due to an IGBT failure. Cable Damage: A broken or intermittent motor supply cable or connector. DC Link Issues:

Never ignore intermittent 607 faults. What happens once a week will eventually happen every cycle, often taking out the entire power module. Use the diagnostic roadmap in this guide, prioritize safety, and restore your machine’s reliability. simodrive 611 error 607

Step 1: Inspect the Mechanical SystemBefore swapping electronics, ensure the axis moves freely. Manually turn the ballscrew if possible (with power off and safety protocols followed). Check if the mechanical brake is receiving the proper 24V signal to release.

| Step | Action | |------|--------| | 1 | Verify 48V DC (42–53V, stable, low ripple) | | 2 | Check pulse enable wiring (X111.663-664) | | 3 | Test with jumpers (isolate external causes) | | 4 | Swap power module with a good axis | | 5 | Read diagnostic with SimoCom U | | 6 | Examine PLC enable sequence timing | | 7 | Replace 48V supply if >8 years old | | 8 | Repair or replace power module if all else fails | can send "funny" signals that make the servo

Error 607 rarely points to a single component. Below are the five primary sources:
