What causes undervoltage in Inovance Monarch 220-NICE-L-C-4011?
T
Todd ParrishAug 27, 2025
Undervoltage in your Inovance Controller can be caused by a few things. It could be due to an instantaneous power failure on the input power supply, so check whether the power fails during running and ensure the wiring of all power input cables is secure. The input voltage might also be too low, so check the external power voltage. In some cases, the drive control board might be failing.

What should I do if my Inovance Monarch 220-NICE-L-C-4011 Controller reports a power supply phase loss?

If your Inovance Controller reports a power supply phase loss, it indicates that the power input phases are not symmetric. First, check whether any phase of the three-phase power supply is lost. Then, verify whether the three phases of the power supply are balanced. Also, check whether the power voltage is normal, and adjust the power voltage if necessary. For 220 V models, you can set FC-01 bit 14 to 1 to cancel detection of this fault.

What are the common causes of motor auto-tuning faults in Inovance Monarch 220-NICE-L-C-4011?
R
Robert Oneill DDSSep 7, 2025
A motor auto-tuning fault in your Inovance Controller can occur for various reasons:
* If learning the stator resistance fails, check whether the motor wiring is correct.
* If learning the magnetic pole position fails.
* If the synchronous motor static auto-tuning mode is selected, but the encoder is not SIN/COS, select another auto-tuning mode or use a SIN/ COS encoder.
* If CD signal fluctuation is large in synchronous motor static auto-tuning, hardware interference exists. Check whether grounding is correct.
* If Leaning the encoder zero- position angle fails in synchronous motor angle-free auto- tuning, obtain the encoder zero-point angle in inspection state, and then perform half- automatic angle-free auto-tuning under normal-speed running.

What should I check if my Inovance Monarch 220-NICE-L-C-4011 indicates a power output phase loss?

Dana ChristianSep 8, 2025
If your Inovance Controller indicates a power output phase loss, the issue likely stems from the output wiring of the main circuit being loose. Check whether the motor wiring is secure and verify whether the RUN contactor on the output side is normal.

How to troubleshoot a RUN contactor feedback abnormal error on an Inovance Monarch 220-NICE-L-C-4011?

xwatsonSep 10, 2025
A RUN contactor feedback abnormal error on your Inovance Controller can have a couple of causes:
* If the feedback of the RUN contactor is active, but the contactor has no output, check whether the feedback contact of the contactor acts properly and check the signal feature (NO, NC) of the feedback contact.
* If the current of the asynchronous motor from acceleration to constant-speed running is too small (? 0.1 A), check whether the output cables UVW of the controller are connected properly and check whether the control circuit of the RUN contactor coil is normal.

What causes the 'door lock disconnected during running' error in Inovance Monarch 220-NICE-L-C-4011?
A
Andrew EvansSep 12, 2025
If your Inovance Controller displays a 'door lock disconnected during running' error, indicated by subcodes 101 or 102, it means the door lock circuit feedback is invalid during elevator operation. Check whether the hall door lock and the car door lock are in good contact. Also, verify whether the door lock contactor acts properly, check the signal feature (NO, NC) of the feedback contact on the door lock contactor, and ensure the external power supply is normal.

Why is my Inovance Controller showing a safety circuit disconnected error?
R
Ryan SantiagoSep 13, 2025
If your Inovance Controller is showing a safety circuit disconnected error (Subcode 101), it means the safety circuit signal has become off. Check the safety circuit switches and their states. Also, verify whether the external power supply is normal, ensure the safety circuit contactor acts properly, and confirm the signal feature (NO, NC) of the feedback contact of the safety circuit contactor.

What to do when the Inovance Monarch 220-NICE-L-C-4011 shows 'Maintenance notification period reached'?
N
Nicole SmithSep 14, 2025
If your Inovance Controller displays 'Maintenance notification period reached', it means the elevator hasn't been maintained within the notification period. Power-off and maintain the elevator or disable the maintenance notification function by setting F9-13 to 0.
