l297 vref
good day... too many question to ask... please help...
this is the data sheet i need help on
https://www.st.com/stonline/books/pdf/docs/1334.pdf
i hav few questions... please help... i am using it to control 2 phase variable magnet bipolar stepper motor
1. could anyone explain to me wad is the purpose of OSC pin?.. i know it is stated as chopper rate... anyone know how to explain this using more simple term?...i dunno wad is chopper even though i read many time the data sheet D....
wad is the value for the RC circuits,,, wad is this for... n wad value i can use,, any?
2. wad is the control pin for??... it stated either to act on A,B,C,D or /INH1/2 faint![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
3. wad is tht /INH1 and /INH2 for?? should i use it if i just wanna control the stepper motor. please explain on this 2 pin,,, i am really headache read over n over again wthout any understanding on this...
4. and how about the SENSE1 and sense2 pin....wad is tht also...
5. how fast the frequency of the step clock can i input to the /clock pin of the L297.... does it depend on the stepper motor i use?...
6. for stepper motor, which part of the data sheet i should refer in order to know how fast the step/clock i can use wth the motor from my controller??
i would b grateful if anyone can help... u can answer part or even one question if u r really busy... any will help....
many many many thanks... in advance...
my warm regards,
sp

Code:
The L297 integratesall the control circuitry required to control bipolar and unipolar steppermotors. Used with a dual bridge driver such as the L298N forms a complete microprocessor-to-bipolar stepper motor interface. Unipolar stepper motor can be driven with an L297 plus a quad darlington array. This note describes the operation of the circuit and shows how it is used.
