AC Drive - Keypad Operation

Your trainer comes ready for the drive to run the fan motor.

1.  Turn the potentiometer knob on the keypad to 100.

2.  Press the green "RUN" button and the motor will start to run.  Notice how it slowly ramps up to speed.

3.  Turn keypad potentiometer to 50 which is the 12 o'clock position.  Notice how the motor speed slowly lowers to half speed.

4.  Press the "FWDREV" button.  Notice the drive slowly ramps down to a stop then begins running in the opposite direction.

5.  Press the red "STOP/RESET" button.

There are three commonly adjusted parameters that we are going to go through changing below.  The acceleration which affects how quickly the motor comes up to speed, the deceleration which affects how quickly the motor stops, and the stop method which switches between the drive decelerating or coasting to a stop.

6.  The acceleration is parameter 1.01.  It determines how long it takes for the motor to get to speed.  To get to it, press the "PROGRAM" button until you see P1.00, press the "UP" button until you get to 1.01, press "ENTER", and change the acceleration from 10.0 to 1.0.  Now repeat steps 1-5 and notice how much faster the motor comes up to speed.

7.  The deceleration parameter 1.02.  It determines how long it takes for the motor to stop.  To get to it, press the "PROGRAM" button until you see P1.00, press the "UP" button until you get to 1.02, press "ENTER", and change the acceleration from 30.0 to 5.0.  Now repeat steps 1-5 and notice how much faster the motor stops.

8.  The stop method is parameter 1.00.  00 is ramp to stop and 01 is coast to stop.  Press the "PROGRAM" button until you see P1.00, press "ENTER", and change the acceleration from 00 to 01.  Now repeat steps 1-5 and notice how much faster the motor coast to stop.
