Goals:
Read error codes and clear faults.
Backup and restore a MOVIDRIVE®B.
Start up the MOVIDRIVE®B in V/f mode.
Run the drive in manual mode.
Examine and edit parameters.
In most cases, it’s much easier and convenient to work with the MOVIDRIVE®B through
MOVITOOLS®. But on some occasions, a laptop may not be available. Or perhaps you need to
do something very simple, such as changing a parameter or two. For these situations, the
DBG60 keypad is a useful tool.
Admittedly, the keypad is far less convenient and a bit more challenging to use because of its
tiny screen and limited controls. But knowing how to use it can be a lifesaver, so it’s worthwhile
to develop your skills. Let’s examine its buttons.

The keypad can be helpful if the MOVIDRIVE®B has halted because of a fault. As you already
know, the unit’s single-digit display isn’t very detailed. Being able to read the full fault code is
much better. Once you know what’s wrong, you can correct the problem and clear the fault.
To demonstrate this feature, you need to force the MOVIDRIVE®B into a fault condition. If
you’ve just completed the Table Positioning exercise, this will be very easy.
Step 1
Set all switches on the control box to the OFF (down) position.
Step 2
Set switches DI 00 and DI 01 to the ON (up) position.
The MOVIDRIVE®B should fault immediately and display a code of F27.
Step 3
Connect the keypad to the MOVIDRIVE®B and wait for it to initialize. If the screen displays
a globe symbol, the keypad language hasn’t been set. Press the SELECT LANGUAGE button.
Then, use the MOVE UP / MOVE DOWN buttons to locate Englisch. Press the CONFIRM button.
Step 4
The current fault code and description will appear on the keypad display.
Question
1. What caused the MOVIDRIVE®B to fault?
Once you’ve identified the fault’s cause, you can correct it and clear the fault.
Step 5
Set switches DI 00 and DI 01 to the OFF (down) position.
Before clearing a fault condition, always confirm that the drive won’t do anything dangerous
when it comes back on. Setting Controller Inhibit (DI 00) to 0 V is always a wise idea.
Step 6
Press the EXIT button.
Step 7
Using the MOVE UP / MOVE DOWN buttons, change MANUAL RESET to YES.
Step 8
Press the CONFIRM button.
The MOVIDRIVE®B will reset and clear the original fault code. If you’ve corrected the problem,
the drive will be ready to run.

The keypad can store a backup of the MOVIDRIVE®B. If desired, this backup can be used to
duplicate the drive setup across multiple units.
Step 1
Press the MENUS button.
Step 2
Press the MOVE UP / MOVE DOWN buttons until COPY TO DBG appears.
Press the CONFIRM button.
The keypad will perform a backup.
We’ll use this backup later on to restore the MOVIDRIVE®B to its original state.
Factory resetting the drive and performing a quick startup in V/f mode is yet another task that
the keypad can do. More sophisticated startups should be done through MOVITOOLS®.
Step 1
Press the MOVE UP / MOVE DOWN buttons until PARAMETER MODE appears.
Press the CONFIRM button.
Step 2
Key in 802 and press the CONFIRM button to access the Factory setting parameter.
Step 3
Press the MOVE UP button until DELIVERY COND.appears.
Press the CONFIRM button to factory reset the MOVIDRIVE®B.
Step 4
Wait for the MOVIDRIVE®B to reset and the keypad to initialize.
Step 5
Press the MENUS button.
Step 6
Press the MOVE DOWN button until STARTUP appears.
Press the CONFIRM button.
The startup process involves setting a series of parameters. You’ll work your way through the
parameter list by pressing the MOVE UP button. If the parameter doesn’t need to be changed,
just press MOVE UP again to go to the next.
If you do need to change a parameter, press the CONFIRM button. If there are a number of
choices, you can use the MOVE UP / MOVE DOWN buttons to select among them. Pressing the
CONFIRM button accepts the change.
If a parameter requires a numeric value, key it in with the number pad and then press the
CONFIRM button. Finally, press the SWITCH button followed by the MOVE UP button to advance to
the next parameter.

Step 7
Select PARAMETER SET 1.
Step 8
Select SINGLE MOTOR.
Step 9
Select STANDARD V/Fmode.
Step 10
Select NO for DC BRAKING.
Step 11
Select the correct motor class. You may need to ask for help if you are not familiar with
SEW-EURODRIVE motors.
Step 12
Select the correct motor model (obtained from the nameplate).
Step 13
Enter the correct motor voltage (obtained from the nameplate).
Step 14
Enter the correct motor frequency (obtained from the nameplate).
Step 15
Enter the MOVIDRIVE®B’s supply voltage (ask the instructor if you’re not sure).
Step 16
Select NO RESPONSE for motor thermal protection.
Step 17
Select YES for CALCULATION.
Step 18
Select YES for SAVE.
Step 19
Press the EXIT button.
Now you can test the MOVIDRIVE®B by running it in manual mode.
Step 1
Press the MOVE UP / MOVE DOWN buttons until MANUAL OPERATION appears.
Press the CONFIRM button.
Step 2
Flip DI 00 to the ON (up) position.

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.

Now, let’s change a parameter that requires a keyed-in value.
Step 7
Press the MOVE UP / MOVE DOWN buttons until PARAMETER MODE appears.
Press the CONFIRM button.
Step 8
Key in 160 and press the CONFIRM button to access the Internal setpoint n11 parameter.
This parameter requires you to enter a numeric value rather than scrolling through a list of
choices. We’ll set it to 1,200 rpm.
Step 9
Key in 1200.
Press the CONFIRM button, followed by the SWITCH button.
Step 10
Press the MENUS button to exit.
To finish, we’ll use the backup stored in the keypad to restore the MOVIDRIVE®B back to the
state it was in at the beginning of this activity.
Step 1
Set all control box switches to the OFF (down) position.
Step 2
Press the MOVE UP / MOVE DOWN buttons until COPY TO MDX appears.
Press the CONFIRM button.
The keypad will restore the backup onto the MOVIDRIVE®B.
Note: If you need to access a menu option and the menus are not displayed on the screen,
pressing the MENUS button will usually bring them up.
