U can answer part or even one question if u r really busy. 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. Does it depend on the stepper motor i use?6. How fast the frequency of the step clock can i input to the /clock pin of the L297. Please explain on this 2 pin, i am really headache read over n over again wthout any understanding on this.4.Īnd how about the SENSE1 and sense2 pin.wad is tht also.5. Wad is tht /INH1 and /INH2 for? Should i use it if i just wanna control the stepper motor. It stated either to act on A,B,C,D or /INH1/2 faint:)3. Could anyone explain to me wad is the purpose of OSC pin? I know it is stated as chopper rate.Īnyone 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. I am using it to control 2 phase variable magnet bipolar stepper motor1. This note describes the operation of the circuit and shows how it is used.i hav few questions. Unipolar stepper motor can be driven with an L297 plus a quad darlington array.
Used with a dual bridge driver such as the L298N forms a complete microprocessor-to-bipolar stepper motor interface. Code: The L297 integratesall the control circuitry required to control bipolar and unipolar steppermotors.
