Rotary encoder to roll the output pulse, through the counting equipment to know its position (PLC) we usually use incremental encoders, the incremental encoder output pulse signal can be directly input to the PLC, the PLC's high-speed counter is used to count its pulse signal, in order to obtain the measurement results. Due to the different phases of the output pulse of the rotary encoder, some rotary encoders output A, B, and Z three-phase pulses, some only need A and B phases, and the simplest only needs A phase. There are up to three groups of three-phase pulses: A, A+, A-, B, B+, B-, Z, Z+, Z-.
Commonly used rotary encoders have 5 leads, of which 3 are pulse output lines, 1 is COM end wire, and 1 is power line (OC gate output type). The power supply can be an external power supply, or it can directly use the power supply of the PLC. The "-" side of the power supply should be connected to the COM end of the encoder, and the "+" side should be connected to the power end of the encoder. The COM end of the encoder is connected with the PLC input COM end, and the A, B, and Z two-phase pulse output lines are directly connected to the PLC input end, and A and B are pulses with a difference of 90 degrees. The rotary encoder also has a shielded wire, which should be grounded when used to improve the anti-interference performance.
Device steps
1. Sturdy device encoder to avoid sensation and loosening
2. When the encoder is wired, please ensure that the load does not exceed the maximum allowable value
3. When the encoder is wired, please ensure that there is no error
4. Tighten the screws of the coupling to avoid loosening during use

Is there still an output after the UPS power is turned off?
1. After the UPS power supply is shut down, the output terminal is still powered, but the UPS power supply does not play a role at this time, and it is in a bypass state.
2. The power supply will not be cut off after the UPS power supply is shut down, because the UPS power supply will go bypass after the shutdown, there is still a mains power input at this time, ...

Motor control mode of Schneider inverter
Fundamentals of magnetic flux vector manipulation
The control of a three-phase asynchronous motor is much more complicated than that of a DC motor because the current, voltage, induced potential, magnetic flux, etc., of the stator and rotor are all alternating.
However, the stator winding of the three-phase asynchronous motor is a symmetrical three-phase winding, which exerts a ...
