Step 3
Key in a speed value and press the
CONFIRM
button. A positive number makes the motor
turn clockwise. To make the motor run counterclockwise, key in the speed and press the
–
button before pressing the
CONFIRM
button.
Step 4
Press the
RUN MOTOR
button to start the motor.
Press the
STOP MOTOR
button when you’re finished.
Step 5
Press the
EXIT
button to leave manual mode.
Reminder: always exit manual mode before disconnecting the keypad. If you fail to deactivate it,
the drive will remain in manual mode and ignore all other control signals.
The keypad isn’t the best tool for editing a large number of parameters, but it’s fine if you have
to change just one or two.
Let’s adjust a few parameters to see how it’s done.
As you probably noticed when you tested the drive in manual mode, the PWM base frequency is
back at 4
kHz, which isn’t pleasant to hear. We’ll change it to 16 kHz.
Step 1
Press the
MOVE UP
/
MOVE DOWN
buttons until
PARAMETER MODE
appears.
Press the
CONFIRM
button.
Step 2
Key in
860
and press the
CONFIRM
button to access the
PWM frequency 1
parameter.
Directly keying in a parameter number takes you straight to that parameter. The keypad display
shows a short description so you can verify that you have the correct one.
In this case, the parameter has a fixed set of choices (2.5, 4, 8, 12, and 16).
Step 3
Use the
MOVE UP
/
MOVE DOWN
buttons to cycle through the choices until you reach
16
.
Step 4
Press the
CONFIRM
button, followed by the
SWITCH
button.
Step 5
Press the
MENUS
button to exit.
Step 6
Run the drive in manual mode to confirm that you’ve changed the PWM base frequency.
