DC Braking Time

DC Brake during Start-up is used for loads that may move before the AC drive starts, such as fans and pumps. Under such circumstances, DC Brake can be used to hold the load in position before setting it in motion.

DC Brake during stopping is used to shorten the stopping time and also to hold a stopped load in position. For high inertia loads, a dynamic brake resistor may also be needed for fast decelerations.

				starts with the Master Frequency reference value.
		2		Operation continues after momentary power loss, speed search
				starts with the minimum frequency.

This parameter determines the operation mode when the AC motor drive restarts from a momentary power loss.

In PG control mode, the AC motor drive will execute the speed search function automatically by the PG speed when this setting isn’t set to 0.
