Chapter 5 Description of Parameter Settings

NOTE: 1. DC Braking during Start-up is used for loads that may move before AC

drive starts, such as fans and pumps. These loads may also be moving

in the wrong direction. Under such circumstances, DC Braking can be

executed to hold the load in position before applying a forward motion.

2. DC Braking during stopping is used to decrease stopping time and also

to hold a stopped load in position. For high inertial loads, a dynamic

braking resistor may be needed for quick decelerations.
