This particular sectional door control system utilizes a frequency converter, motor, absolute encoder and control center, and is equipped with a power off memory function and identification function. By using limit encoding technology, the door control unit has an average precision of 1mm.

Advantages
1. LCD Human to Machine Interface
The interface directly monitors the internal system as well as external signals (radar, security protection, buttons). This reduces maintenance labor costs and increase the efficiency. The main display parameters include the degree to which the door is open, operating time, and other related codes.

2. Absolute Limit Control
The absolute encoder is a key component in full range limit control technology. The FS/F series control system uses a single turn encoder, providing a power-off memory function and identification functions. The absolute encoder also has no accumulative errors, a problem common among traditional encoders. The absolute encoder guarantees an average precision of 1mm.

3. Frequency Modulation
The speed of the sectional door can be adjusted, and there is no need to reset the limit switch.

4. Functional Port
The input port is responsible for door opening/closing, door stop, security protection, sensors, manual switch, one key startup/shutdown, interlock input and external fault inputs. The output port is responsible for interlock output and fault output.

5. Reliable Drive System
The drive system is comprised of a number of individual parts: the CPU chips are high performance 32 bit DSP chips from the American company TI, and the peripheral interface circuit utilizes Toshiba optical coupler isolation technology and supports hot plugging. The power modules are IPM modules and inverter modules from Infineon, while the drive system ensures the industrial door control system operates normally for at least 200,000 cycles.

6. Smooth Startup and Stop
With the application of an IPM module, the sectional door operator achieves an intelligent control and protection. Along with the SPWM drive method, a smooth start up and stop function are provided, extending the service life of mechanical transmission components.

7. Convenient Maintenance
For non-destructive malfunctions and fault, the system can give a clear direction for inspection and repair. Standard terminals are also installed on the system, ensuring the entire system works seamlessly, and saves time.

8. Overload Protection
The protection system effectively protects the motor against overload or motor stalling faults.
