ENCODER TECHNOLOGY THEORY
An incremental rotary encoder outputs a certain amount of Pulses
per Revolution. The higher this PPR number, the smaller the angle
between each pulse. This PPR number is fixed for ordinary
incremental encoders. Programmable incremental encoders can adjust
this value to a desired number by a software change.
Today most incremental encoders have a Push-Pull (HTL) or RS422
(TTL) output driver, these have replaced most of the older output
circuits like Open Collector NPN, Open Collector PNP, Voltage
Output.
Push-Pull (HTL) circuits, also known as Totem Pole, provide a
signal level which corresponds to the applied supply voltage. The
supply voltage typically ranges from 8 to 30 VDC.
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.
About Encoder Vibration
Vibration acting on an encoder always cause wrong pulse easily.
So we have to pay more attention to encoder working place.
The more pulse per round, the narrower groovy spacing of grating,
ore effect to encoder by vibration, when motor speed is low or even
stopped, vibration acting on encoder shaft or encoder shell would
cause grating vibration, in this way, encoder might show wrong
pulse signal.
