Hello everyone! Please explaine me, please!

If i understand ● Pulse + Direction: 

Pulse: on one PTI input V90 come pulse (for example q0.0 from CPU1215,  36/8="+24V" Pulse PTI_A,   37/8="0V" )

Direction:on other PTI input V90 come direction (for example q0.1 from CPU1215,  38/8="+24V" Direction PTI_B,   39/8="0V" )

1 .What means "positive logic=0" , "negative logic=1" for● Pulse + Direction?

(maybe we can changing direction without changing polarity of pulse.....i  dont sure///, and why positive logic is 0 (=0))

2. What means this line 1(see attachment)?

3. What meas ● AB track pulse? A pulse, B pulse?  I see the pulse A i B are displaced relativ each to other (see in attachment line 2)?

4. How in this case we change direction (● AB track pulse)?

5. What is diference between thise two forms pulses?

6. What to do, if in CPU for example 1215 is available only AB track pulse? Not pulse+direction

Thank everyone!

Ad. 1 positive logic = 0 / negative logic = 1 refers to parameter P29010 bit 1 values. And in fact it has no direct meaning to you , as you can set this parameter to integer values 0..3, so don't bother.

Ad. 2 think of it as a columns separating line of the table.

Ad. 3 read something on the topic of a incremental encoders with AB quadrature tracks, e.g. here

Ad. 4 -> Ad. 3
Ad. 5 AB track has higher resolution - it has 2x the bandwidth of the pulse/direction solution

Ad. 6 Use AB track, i.e. set V90 to mode 1.

Thsnk you Jaced d for ansering!

If i understood the form ● AB track pulse use the same two signals: pulse and direction (as in form ● Pulse + Direction) ?

For example

Pulse: on one PTI input V90 come pulse (for example q0.0 from CPU1215,  36/8="+24V" Pulse PTI_A,   37/8="0V" )

Direction:on other PTI input V90 come direction (for example q0.1 from CPU1215,  38/8="+24V" Direction PTI_B,   39/8="0V" )

it is  true?

Thank You!

This may sound a little bit philosophical, but to be politically correct  :

- both solutions use the same terminals on V90 AFAIK

- when you use Pulse/Direction, you refer to the terminals as Pulse/Direction

- when you use AB track, you refer to the terminals as A-tack/B-track.
