The speed is linear with the input signal. This is for low to medium speed 
motor. 
ON 
The response to input is exponential and thus soften the control around 
the center zero speed point. This is suitable for high speed and very 
sensitive motor.

LOCKED ANTI-PHASE 
Motor stops when the input signal is 2.5V. Motor moves in one direction 
when the input is < 2.5V (0 - 2.5V) and in another direction when the 
input is > 2.5V (2.5 - 5V). 
SIGNED MAGNITUDE 
AN1 and AN2 controls the speed of the motor. Motor stops when the 
input is 0V and run at full speed when the input is 5V. IN1 and IN2 is 
digital inputs and it controls the direction of the motor respectively.
