automatic reset settings found in the Parameters (3)/Automatic Reset (3.10) menu for desired settings.
14 The default display has been configured to wait for 2 minutes of keypad inactivity before switching to the multi-monitor
display. If this is not acceptable, see Timeout Time (5.7.1) and Default Page (5.7.2) for desired settings.
15 Manually run the drive throughout its entire operation range while observing operation.
If the drive trips on an over-current during acceleration, adjust the Accel time 1 (3.4.2).
If the drive trips on an over-voltage during deceleration, adjust the Decel time 1 (3.4.3).
If excessive vibration of the driven load is noted at specific input frequencies, use Prohibited Frequencies (3.7) to
eliminate this vibration.
16 Determine whether the speed reference signal is 0 to 10 Vdc or a 4 to 20 mA. Connect signal wires, and place the DIP
switch in the appropriate position.
NOTE:
Ensure that the drive power is off before changing the DIP switches.
17 Verify the speed reference signal for proper polarity and operation.
18 Place the drive in AUTO mode at the keypad. Verify that the drive is controlled properly by the building automation
system. Observe if the speed command can achieve the minimum and maximum speeds desired. If not, scale as
required.
19 Configure the Password and Access Level, if desired. This prevents unauthorized parameterization using the keypad.

Factory Reset
Since it is often unknown if any other users have attempted to run the unit, it is
recommended to complete a Factory Reset to return the drive to known factory
settings. Do the following to complete a Factory Reset:
At the drive keypad, select:
User Settings > Parameter Backup > Restore Factory Defa > Activate.
The drive restarts, the Siemens splash screen displays, and the Startup Wizard
automatically begins. See the Startup Wizard (P1.19) section for further details.
