The fast door control box is a special inverter developed according to the application needs of customers in the rolling door machine and fast door industry. It integrates PLC + inverter + display functions. The product has high integration, high reliability and complete functions; it can be completely replaced The solution of PLC+frequency converter+display; Company product features: Support up to three limit working modes. In absolute working mode, the door position is changed artificially due to power failure, which will not affect the normal use of the door machine (no need to re-learn or reset manually) . Support the real-time display of the current position pulse, support the operation panel up and down, manual automatic conversion, and emergency stop operation (the door machine can be manually controlled to work normally inside and outside the door) Comprehensive technical indicators of fast door control box 1. Input and output characteristics Input voltage range: 220V±20% Output voltage range: 0～rated input voltage Output frequency range: 0～100HZ 2. Peripheral interface characteristics 16 isolated external signal digital inputs: X0-X9, FWD, REV Incremental encoder interface: input AB pulse frequency up to 100KHZ Absolute encoder communication interface: 485 communication mode, baud rate 19200bps Relay output: 2 multi-function relay signal output 3. Technical performance characteristics Control method: SVPWM Overload capacity: 150% rated current 60s; 180% rated current 10s Starting torque: 1.0Hz/150% Carrier frequency: 1.0K～10.0KHZ V/F curve: V/F curve can be set arbitrarily Acceleration and deceleration control: any choice of 16-segment acceleration and deceleration time 4. Protection features Automatic shutdown when running overtime If the encoder is disconnected, it will stop automatically when damaged; Absolute encoder communication error, overtime automatic protection; Protection functions such as overcurrent, overvoltage, undervoltage, overtemperature, phase loss, and overload
