Main Features Of China Cheap Price Close Loop Power Inverters VFD AC Drives Frequency Inverter
1. Drive both the asynchronous motor and permanent magnetic synchronous motor (PMSM), and provide
multiple encoder interfaces.
2. Support motor auto-tuning (static auto-tuning and complete auto-tuning).
3. Support multiple speed sources, multi-speed and analog setting.
4. Guarantee good elevator riding comfort with flexible startup curves, multi-segment S-curve setting, and
four groups of acceleration/deceleration time.
5. Support emergency evacuation at power failure with the 48 V battery power supply.
6. Provide various elevator-related functions, including enable detection, brake contactor control, output
contactor control, slow-down judgment, overspeed protection, speed deviation detection, door preopen,
contact stuck detection, motor overheat detection, and startup pre-torque compensation.
7. Support connection to the external operation panel through the RJ45 interface, making the operation
and commissioning simpler and easier.
8. Provide the built-in DC reactor and braking unit, which improves the output power factor and reduces
costs of peripheral devices.
9. Separate air duct with conformal coating process, professional manufacturing platform, and advanced
process make good product quality.
10.Have the lightning protection design and the strong anti-interface capability, compliant with the EMC
standard.
11.Support Synchronous and asynchronous motors.Support the Heidenhain encoder.
