yes i have that sheet. but i need to know how long pulses are.
however, i tried this sketch:

int pin = 7;

unsigned long duration;

void setup()
{
pinMode(pin, INPUT);
Serial.begin(9600);
}

void loop()
{
duration = pulseIn(pin, HIGH);
Serial.println(duration);
}

it gave me values around 9300. does that mean that the motor controller pulses are 9,3 millisec long?
