Dedicated control algorithm for speed door

◦ Built-in special door control program + simple PLC, eliminating the need for an external PLC controller.

◦ Minimum terminal start response time: 0.01s; outputs 150% rated torque at low speed without stalling under heavy loads.

◦ Automatically decelerates before door closing, delivers soft stop with no impact or rebound.

◦ Optional control modes: V/F mode, open-loop SVC vector mode.

Two limit / positioning modes

◦ Mechanical limit: Connect travel limit switches, factory default mode with easy commissioning.

◦ Incremental encoder: High-precision position control, ideal for high-speed doors.

High reliability & anti-interference performance

◦ Integrated EMC filter, suitable for heavy industrial interference environments (welding machines, punching presses).

◦ IP20 protection grade, flame-retardant PC housing, fully coated PCBA to resist dust and oil mist.

◦ Wide voltage tolerance: ±15% grid voltage fluctuation, compatible with aging factory power supply systems.

Low noise & energy efficiency

◦ Carrier frequency up to 12kHz for quiet operation.

◦ Over 30% lower power consumption compared to contactor control, doubles motor service life.

Comprehensive dedicated door control functions

◦ Double-door interlock, automatic door opening, air curtain interlock control.
