BT300 Variable Frequency Drives
21
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.
22
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.
23
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: Only change the DIP switches with the drive power off.
24
Verify the speed reference signal for proper polarity and operation.
25
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.
26
Configure Password and Access Level if desired. This prevents unauthorized parameterization via
the keypad.
