DBT Reach Drive User Manual

When Start At Powerup in 2 wire control is configured, the drive will start if the start
permissive conditions are met within 10 seconds of drive power being applied. An
alarm will be annunciated from application of power until the drive actually starts,
indicating the powerup start attempt is in progress. If the drive has not started within
the 10 second interval, the powerup start attempt will be terminated.

Vector Control Option

A powerup delay time of up to 30 seconds can be programmed through [Powerup
Delay (167). After the time expires, the drive will start if all of the start permissive
conditions are met. Before that time, restart is not possible.

The Reach Drive offers several methods for stopping a load. The method/mode us
defined by Stop/Brk Mode A/B (155 and 156). These modes include:
