Syncro/Digital Converter NT5700 Series

It converts and outputs the synchronous (Celsyn) electrical signals corresponding to the amount of rotation and movement of the machine into absolute BCD digital signals.

The zero hold function suppresses the output of abnormally large values (for example, scaling to 359 degrees when at minus 1 degree) when the synchro transmitter rotates in the negative direction from the zero position. The upper limit hold function allows you to set the maximum output value. It maintains the specified value (reference lift) while lifting the door body with a hoist beyond the maximum opening. It is also possible to set multiple different scales. The NT5700 uses two different scales based on the opening. This function accommodates the stage winding correction of the wire drum. The set values can be changed using the main unit switch, allowing for fine adjustments on-site. With the linearizer option, you can store any conversion table in ROM, enabling more complex opening conversions, such as converting the arc opening of a radial gate to a vertical opening. When you want to set the current angle of the synchro transmitter to the zero output point (zero setting), it can be done with just one push of a button on the equipment body (this is done when the gate is fully closed), making fine adjustments on-site easy. You can set the direction of increase or decrease of the output value in relation to the rotation direction of the synchro transmitter.
