Technical terms
Specification
 
Two signals with 90°phase difference and zero-position signal
 
Two signals with 90°phase difference on two ways and zero-position signal
 
UVW signal
 
The relationship of three-way signal(electrical degree) representing 120°phase difference
 
Voltage output
 
Earth with NPN type transistor emitter, circuit outputting collector and load resistance
 
Open collector output
 
NPN type circuit outputting directly from transistor emitter
 
 
Long distance driver output
 
To use integrated circuit with long distance output, the signal is output in two directions very fast, with strong antijamming capability, which can also test the disconnection of the cable.
 
 
 
Long distance receiver
 
To receive with the dedicated IC outputting signals from the driver. When in use, please be noted that the long distance driver must match the long distance receiver. If you choose to use 75113 long distance driver for output, you should use 75115 circuit receiver for receiving. If not matched, it shall be affected for its use.
 
Complementary output
 
 
Connect NPN type and PNP type geminate transistors emitter with output circuit. This kind of circuit can response rapidly, and can transmit in long distance.
 
Injection current permitted
 
The current value absorbed most for one-way signal of the encoder.
 
Output resistance
 
Internal impedance of the output circuit
 
Minimum load impedance
 
The minimum load impedance
 
Allowable shaft load
 
The axle and radial load capacity the shaft can bear
 
accuracy
 
Half of the difference between the rotating angle obtained by accumulation of the output pulse numbers and theoretical rotating angle. Plus positive and negative signs.
 
Periodic error
 
The difference between the output pulse number period and theoretical pulse number period.
 
The difference between adjacent periods
 
The difference between adjacent pulse periods
 
 
Incremental
 
The way to output pulse train or the periodic pulse train of the sine wave. Its position is obtained through accumulation.
 
Absolute
The way to output mechanical displacement as the absolute position by binary code or Gray code.
 
Positive logic
 
The way to output mechanical displacement as the absolute position by binary code or Gray code.
 
Negative logic
 
Symbol “1” is the output logic corresponding to output voltage “L”
