Delta Electronics VFD-VL manual Operation and Start Up

Chapter 3 Operation and Start Up

„Setting the acceleration/deceleration with Pr.01-23 and the setting 08 (the 1st, 2nd acceleration/deceleration time selection) and 09 (the 3rd, 4th acceleration/deceleration time selection) of multi-function input command Pr.02-01~02-08.

„Settings of acceleration/deceleration time: Pr.01-12~Pr.01-19

Settings of Pr.01-12 to	Accel Time 1	0.00~600.00 sec
Pr.01-19	Decel Time 1	0.00~600.00 sec
	Accel Time 2	0.00~600.00 sec
	Decel Time 2	0.00~600.00 sec
	Accel Time 3	0.00~600.00 sec
	Decel Time 3	0.00~600.00 sec
	Accel Time 4	0.00~600.00 sec
	Decel Time 4	0.00~600.00 sec

NOTE: it is recommended to set the acceleration/deceleration time to the small value in the trial run and execute smooth test after all the actions are correct.

„Settings of S curve: Pr.01-24~Pr.01-30

Settings of Pr.01-24 to	S-curve for Acceleration	0.00~25.00 sec
Pr.01-30	Departure Time S1
	S-curve for Acceleration	0.00~25.00 sec
	Arrival Time S2
	S-curve for Deceleration	0.00~25.00 sec
	Departure Time S3
	S-curve for Deceleration	0.00~25.00 sec
	Arrival Time S4
		0: Output waiting
	Mode Selection when	1: Zero-speed operation
	Frequency < Fmin	2: Fmin (4th output
		frequency setting)
	Switch Frequency for	0.00~120.00Hz
	S3/S4 Changes to S5
	S-curve for Deceleration	0.00~25.00 sec
	Arrival Time S5

NOTE: it is recommended to set the S curve time to 0 in trial run and execute smooth test after all the actions are correct.
