BT300 Variable Frequency Drives
Step
Check
Description
1
Apply power to the drive. Make sure that all three input phases are present and that the input
voltage is correct for the system being set up. Verify that the drive's keypad display is on.
NOTE: At this time, if the display indicates a fault, press and hold (for about a second) the
Back/Reset button to reset (acknowledge) the fault.
2
Complete the Startup Wizard to enter the motor data and essential operating parameters.
Note: This should be activated when the unit is first powered up. If not , then it is recommend to
reset the drive to factory default to return to a good known starting configuration. This can be
completed by navigating to the following in the menu structure:
User Settings (6)…Parameter Backup (6.5)…Restore Factory Defaults (6.5.1)... Activate
Refer to the Operator's Manual (DPD01149) for detailed information about the Startup Wizard.
3
Complete any other required wizards found in the Quick Setup (1) menu.
Refer to the Operator's Manual (DPD01149) for detailed information about the wizards.
4
Complete any other application specific settings for the site as required.
5
The automatic reset is configured for 30 second intervals and 10 reset attempts.
If this is not acceptable, configure the automatic reset settings found in Parameters (3)
…Automatic Reset (3.10) menu for desired settings.
6
Configure Motor Switch (3.1.2.2) if a disconnect between the drive and the motor exists.
7
The default display has been configured automatically to wait for 2 minutes of keypad inactivity and
then switch to the multi-monitor display. If this is not acceptable, then refer to Timeout Time (5.7.1)
and Default Page (5.7.2) for desired settings.
8
Place the drive in HAND mode at the keypad.
9
Press the green start key. Ramp the drive speed up to ten (10) hertz. Verify that the direction of the
motor rotation is correct.
Note:
If the direction of the motor rotoation is incorrect, turn the drive power off. Wait for 5 minutes. Swap
wires on the motor terminals (T1(u), T2(v)) or on a bypass unit, the output terminals of the overaload
relay. Tighten the terminal lugs, reapply power, and recheck the direction of the motor rotation.
10
With correct motor rotation, manually run the drive throughout its entire operation range while
observing operation.
If the drive trips on an over-current during acceleration, adjust the acceleration time (3.4.2).
If the drive trips on an over-voltage during deceleration, adjust the deceleration time (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.
11
Determine whether the speed reference signal is a 0-10vdc or a 4-20mA. Connect signal wires and
place DIP switch in the appropriate position.
Note: DIP switches need to be changed with the drive power off.
12
Verify the speed reference signal for proper polarity and operation.
13
Place the drive in AUTO mode at the keypad. Verify 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.
14
Configure Password and Access Level if desired. This prevents unauthorized parameterization via
the keypad.
Place a "X" in the check column when completed. Place a "n/a" if not used.
