Rockwell Automation Liqui-Flo DBT Reach Drive - Manual (Page 63)

Parameter Descriptions 3-37
The Accel Time parameters set the rate at which the drive ramps to its output
frequency after a start command or during an increase in command frequency (speed
change). The rate established is the result of the following equation:
(Maximum Speed / Accel Time) = Accel Rate
Two accel times exist to enable acceleration rate changes “on the fly” using a building
automation system command or digital input, if configured.
Sets the rate of deceleration for all speed decreases.
(Max Speed / Decel Time) = Decel Rate
Two decel times exist to enable deceleration rate changes “on the fly” using a building
automation system command or digital input, if configured.
Enables/disables dynamic brake operation when drive is stopped. DB may operate
when drive is stopped. DB may operate if input voltage becomes too high.
Disabled = DB will only operate when drive is running.
Enabled = DB will only operate when the drive is energized.
