Hello. i am using AT89c51 micro controller in driving bipolar stepper motor. can someone give me idea on generating PWM clock signal to the L297???(like period, pulse width, duty cycle, etc) i have read somewhere that if have wrong clock signal, the motors will be destroyed. :shock::shock:
according to me steeper motor does't require PWM it just required pulse and no matter of duty cycle.
and servo motor required PWM so for steeper motor just give pulses to IC and keep current at low. and motor will not get destroy.

sir as you given link they required 50% duty cycle and can be achive with timer is it right?
bcoz in timer other work can be done.
