Application Areas

Residential Elevator Scenarios

Suitable for low-rise (3-10 floors), mid-rise (10-30 floors), high-rise (30-50 floors) and super high-rise (above 50 floors) residential elevators, including ordinary commercial housing, high-end residences and villa elevators.

Smooth acceleration and deceleration, low torque ripple deliver a comfortable riding experience
Energy-saving features (especially models dedicated to PM motors) reduce residential energy consumption costs
Long-life design minimizes later maintenance frequency

Commercial Building Elevator Scenarios

Covers passenger elevators, escalator supporting drives (partially adapting to escalator frequency conversion needs) and cargo elevators in commercial venues such as office buildings, shopping malls, hotels and exhibition centers.

Supports frequent start-stop and fast-response operation requirements
Safety functions like star-connection contactor control meet the high-traffic usage scenarios of commercial buildings
Wide voltage adaptation copes with power supply fluctuations in commercial buildings

Special Elevator Scenarios

Includes hospital-specific elevators (stretcher elevators), industrial plant cargo elevators, warehouse heavy-load elevators, small service elevators and barrier-free elevators.

Stable torque output under heavy-load conditions
Safety functions such as anti-slip-down and UCM protection meet the safety requirements of special scenarios
Customizable power satisfies special load/speed needs

Supplementary Sub-scenarios

Old Elevator Renovation: Compatible with both induction motors and PM motors, can directly replace traditional inverters without major modifications to the original circuit
Energy-saving Renovation Projects: High-performance torque compensation and low energy consumption of PM motor-specific models suitable for elevator systems in buildings with high energy-saving requirements
Special Environment Elevators: Supports simplified installation (output contactor-less design) to fit elevator machine rooms with limited space

Frequently Asked Questions

Q: The elevator occasionally has a "jerking feeling" when starting or stopping, instead of smooth acceleration/deceleration. What's the reason?

A: It's most likely that the acceleration/deceleration time or S-curve characteristic parameters are not properly adjusted, leading to poor matching with the elevator load. It could also be due to improper setting of feedforward control parameters, causing delayed speed response. You can first readjust the acceleration/deceleration curve according to the elevator's common load range, then calibrate the feedforward control gain.

Q: The inverter displays an "overcurrent" fault. It can temporarily recover after a restart but occurs frequently. How to troubleshoot?

A: First, check if the motor wiring is loose or oxidized, especially if the contacts of the star-connection contactor are ablated (focus on PM motor models). Then confirm if the motor insulation is aging or if the load is overweight (e.g., the elevator runs at full load for a long time). If both are normal, the inverter's internal current detection module may be faulty and require inspection and repair.

Q: After retrofitting an old elevator, the "anti-slip-down function" occasionally triggers falsely, causing the elevator to stall at startup. How to solve this?

A: The brake of an old elevator may be severely worn, leading to delayed brake feedback signals and the inverter misjudging it as "slipping." You can first adjust the sensitivity threshold of the anti-slip-down function and extend the signal detection time. At the same time, check the brake wear and replace the brake pads or adjust the brake clearance if necessary.

Q: The PM motor model makes more noise during operation than the induction motor model, and torque ripple is noticeable. Is this normal?

A: No, it's not normal. It's most likely that the motor self-learning was not properly performed, and the inverter failed to accurately match the PM motor parameters (such as magnetic pole position and stator resistance). It could also be that the torque compensation parameter is set too high. You can re-run the elevator-specific self-learning (even with steel cables attached) and then reduce the torque compensation gain to optimize operation smoothness.

Q: When using UPS for rescue operation after a power outage, the inverter occasionally fails to start or shuts down immediately after starting. What's the problem?

A: First, confirm if the UPS voltage is within the compatible range (200V class: 48VDC~340VDC; 400V class: 48VDC~680VDC). Low voltage will trigger protection. Then check if the UPS capacity is sufficient, especially when the elevator load is large--small-capacity UPS may not be able to drive it. In addition, if the control power supply is not separated from the main circuit power supply (without the optional part), it may also cause unstable power supply and trigger shutdown.

Q: After the inverter has been running for several years, it shows an "overheating" alarm, especially in summer. How to handle this?

A: First, clean the dust on the inverter's cooling fan and heat sink (elevator machine rooms usually have a lot of dust, which can easily block them) and check if the fan speed has decreased or if it has stopped. Then confirm if the machine room ventilation is good and if the ambient temperature exceeds the inverter's operating range. If it's a heavy-load condition, the 50% ED rated load may not be properly matched, and long-term overload operation can cause overheating. You need to adjust the operating load or replace it with a larger capacity model.

Q: Encoder-related alarms occur frequently, such as "encoder signal loss." The wiring is checked and normal. What's the reason?

A: The encoder itself may be aging (e.g., the battery of the absolute encoder is dead) or the connection between the encoder and the motor shaft is loose. It could also be a fault in the inverter's encoder signal interface module. You can first replace the encoder battery (if replaceable) and re-fix the connecting shaft. If the error still occurs, use a multimeter to detect the voltage and waveform of the signal interface to determine if it's an internal inverter fault.

Q: The CANopen-Lift protocol fails to connect to the elevator main control board. The parameters are set correctly, but communication still fails. How to troubleshoot?

A: First, confirm if the protocol has been activated (some models require separate activation for the protocol, which is not enabled by default). Then check if the shield layer of the communication cable is properly grounded to avoid electromagnetic interference (wiring in elevator machine rooms is complex and prone to interference). In addition, the protocol version of the main control board must match the inverter--for example, models with under-development DCP3/DCP4 protocols cannot be connected to old-version main control boards.
