Simodrive 611 Universal: Error 607 Troubleshooting Guide

Step 1: Visual and Power Checks

• Check the 48V LED on the power module (usually labeled “Vdc logic” or “48V”). Off or flickering → problem with 48V supply.
• Measure voltage between terminals X181 pin 1 (P48) and pin 2 (M) on the power module. Should be 48V DC ±5%.
• Check DC link LED (red). If off, the main contactor or supply module is not energizing.
