8.2ANALOG/PWMINPUTMODE
In Analog/PWM input mode, the speed and direction of the motor is controlled by the analog
voltage or PWM signal. The valid input range is 0 – 5V and it’s very easy to control by using
a potentiometer. For example, the motor can be controlled by a joystick or foot pedal with
potentiometer.
NOTE: The Analog/PWM signal to stop the motor (2.5V if SignMagnitude mode is off,
0V otherwise) must be available when the SmartDriveDuo60 is turned on. Else, the driver
willshowInputErroruntilthecorrectsignalisavailable.
Analog input mode is selected by setting SW1 to 0 (Down) and SW2 to 1 (Up). PWM input
mode is selected by setting SW1 to 1 (Up) and SW2 to 0 (Down). SW3 – SW6 can be
configureddependingontherequirementoftheuser.

Analog Input Mode – The input is analog signal. The filter
capacitor is not connected and the input signal is not filtered.
SW1isforInput1whileSW2isforInput2.
PWM Input Mode – The input is PWM signal. The filter
capacitor is connected and the input signal is low pass filtered to
be an analog signal. SW1 is for Input 1 while SW2 is for Input 2.

Off – The speed is linear with the input signal. This is for low to
mediumspeedmotor.
On –The response to input is exponential and thus soften the
control around the center zero speed point. This is suitable for
highspeedandverysensitivemotor.

Locked AntiPhase – Motor stops when the input signal is 2.5V.
Motor moves in one direction when the input is < 2.5V and in
another direction when the input is > 2.5V. Recommended this
modeifcontrolledusingBreakoutboardwithJoysticksoldered.
Signed Magnitude – AN1 and AN2 controls the speed of the
motor. Motor stops when the input is 0V and run at full speed
