P+F encoders are devices that compile signals (e.g. bit streams) or data and convert them into signals that can be communicated, transmitted, and stored. The P+F encoder converts angular or linear displacements, the former known as the code disc and the latter into an electrical signal. Therefore, the phenomenon: 1. When the rotating P+F encoder is bad (no output), the inverter cannot operate normally, and the running speed becomes very slow, and the inverter is protected in an instant, and the display of "PG disconnection" is displayed. Joint action talent works. In order for the electrical signal to rise to a higher level and generate a square wave pulse without any disturbance, it is necessary to use electronic circuits to deal with it. The connection method between P+E encoder pq wiring and parameter vector inverter and P+F encoder pq, it is necessary to correspond to the type of P+F encoder pgGenerally speaking, P+F encoder pg type is divided into three types: differential output, open collector output and push-pull output, and the signal transmission method needs to take into account the interface of the inverter PG card, so the appropriate PG card type or setting is reasonable.
P+F encoders are generally divided into incremental and type, and there are big differences between them:
In the case of incremental P+F encoders, the bearing is confirmed by the number of pulses calculated from the zero sign, while the bearing of the P+F encoder is confirmed by the reading of the output code. In a circle, the reading of the output code for each direction is weiyi;
As a result, the P+ encoder is not separated from the actual orientation when the power supply is disconnected. If the power is turned on again, the azimuth reading is still current and valid; Unlike incremental P+F encoders, it is necessary to look for the zero symbol.
The series produced by the manufacturers of P+F encoders are very complete, generally yes, such as elevator type P+F encoders, machine tool P+F encoders, Tongfu motor type P+F encoders, etc., and P+F encoders are intelligent, with a variety of parallel interfaces to communicate with other equipment.
The P+F encoder is a device that converts angular or linear displacement into an electrical signal. The former becomes the code disc, the latter is called the yardstick, according to the readout method P+F encoder can be divided into touch type and non-touch type, the brush output is selected, and a brush touches the conductive area or the absolute green area to indicate that the condition of the code is "1" or "0"; The non-touch bearing sensitive element is a photosensitive element or a magnetic sensitive element, and when selecting a photosensitive element, the light transmission area and the opaque area indicate that the condition of the code is 1" or "0"
