Symptoms
ThyssenKrupp Synergy controller displays fault indicating drive system malfunction requiring immediate inspection of the drive unit and safety circuit integrity.
Possible Causes
- Drive inverter hardware fault detected by the controller safety supervisor
- Safety circuit interruption from door interlock or car safety edge
- Encoder feedback loss causing speed deviation beyond threshold
- Brake monitoring relay detected insufficient braking torque
Troubleshooting Steps
- Step 1: Access the Synergy controller diagnostic menu and read the fault log
Fault code and timestamp displayed on the HMI panel - Step 2: Check the drive status LEDs on the inverter module
Green LED solid indicates drive ready; red flashing indicates active fault - Step 3: Inspect safety circuit continuity using the test points on the controller board
Safety chain shows closed loop with no breaks - Step 4: Verify encoder connection and signal quality at the drive terminal
Encoder pulses show clean square wave on oscilloscope
How to Reset
Reset by: 1) Clear the fault from the diagnostic menu. 2) Run a service reset cycle. 3) Verify the elevator performs a successful releveling test before returning to service.
Common Replacement Parts
- TCM-DRV-001: Synergy drive inverter module (Match to elevator power rating)
Frequently Asked Questions
- Q: Can I reset the fault without investigating the cause?
No. The Synergy controller requires fault cause verification before allowing reset to prevent repeated safety circuit violations.
