Hello,
I am looking for a way to control DC motor( Pololu 12V 100:1 z encoder 64 CPR 37Dx73L mm) through Pololu Driver 36v4. I have found in datasheet:
“Direct PWM mode is selected by setting the PWMMODE bit in the OFF register.”
And setting PWM into STEP/AIN1 and DIR/AIN2 low from ArduinoMEGA.
Is it all what should be done?
I have problem because at full PWM I have only 1/10th of nominal speed (at 12V) of the motor.
-Even when I use just digitalWrite(STEP,HIGH) it looks the same.
-By the way, when I plugged motor straight into 12V, it works fine about 100 RPM (with current around 250mA).
Could You help me with some specified informaction about setting of driver?
Piotr
