Encoder Operation method
With proper connections you can use the Push Pull interface to
replace true open collector circuits by using an external diode
connected in a way to limit the direction of the current for RS422
(TTL) circuits provide a constant 5 V signal level that is not
dependent on the supply voltage. Two supply voltage ranges can be
selected: From 4.75 to 5.5 VDC (can be used to replace open
collector output drivers) or from 8 to 30 VDC. Using differential
signals the output fully complies to the RS422 standard.
The differential outputs have the highest frequency response
capability and the best noise immunity. To ensure this the receiver
should also be a differential.
Replacement of Older Output Drivers
A logic gate interprets certain input voltages as high (logic 1) or
low (logic 0).
TTL (transistor-transistor-logic): A signal above 2 V is
interpreted as logic 1 and a signal less than 0.8 V is interpreted
as logic 0. The output voltage ranges between 0-5 V.
HTL (high-threshold-logic): A signal above 3 V is a logic 1 and a
signal less than 1 V is a logic 0. The high output signal level is
dependent from the supply voltage. Because of the higher voltage
difference between logic 0 and 1, the HTL logic is more immune to
interference and more resistant against electrical noise.
Mechanical degree is the actual rotation of the shaft in degrees.
Electrical degree is used for electrical signals. The required time
for completing one alternating voltage/current cycle is defined as
360 electrical degrees (el°). For incremental encoders, one cycle
is equal to one complete pulse. With a given PPR the electrical
degree can be converted to mechanical degree for any incremental
encoder.
