Frequently Asked Questions

All Product Parts Procurement Installation Certification Shipping After-Sales
What is required for elevator commissioning?
Commissioning requires completed installation, correct wiring, parameter setup, safety-circuit verification, functional tests, load tests and documented results.
How do I size a replacement elevator inverter for an existing traction motor?
Use the motor nameplate, required output current, overload duty, supply voltage and elevator operating conditions. Check motor type, feedback and brake-control integration as well. Matching only the kilowatt rating can miss important current, control or duty requirements.
Can elevator software parameters be restored after controller replacement?
Yes when a valid backup and compatible hardware and software are available. Parameters must be reviewed and commissioning tests completed before service.
What is the intended application of Landing Door Panel?
Landing Door Panel is grouped for the elevator or escalator function represented by the listed product options. Confirm the exact model and application before selection.
How do I verify an elevator encoder specification?
Check encoder type, resolution, supply voltage, output signal, shaft size, mounting, connector and compatibility with both the motor and drive.
What is the minimum order quantity for elevator parts?
MOQ varies by stock status, manufacturer, customization, tooling and packaging. Request sample and production quantities separately.
How should elevator glass and decorative panels be packed?
Use protective film, corner guards, non-abrasive separators, rigid cases, upright orientation where required and clear fragile-handling marks.
Can elevator circuit boards be repaired instead of replaced?
Some boards can be repaired after professional diagnosis, but safety-critical damage, unavailable components, burned multilayer traces or corrupted firmware may make replacement safer and more economical.
