Frequency For Smart Start; Accel. Time For Smart Start; Broken Belt Detection, Min. Line Speed Of Broken Belt Detection; Allowance Difference Of Reel Diameter Of Broken Belt Detection - Delta VFD-VE User Manual


Example: Assume that the tension feedback 0~100% corresponds to loose tension to
tight tension, Pr.08-26=50% and Pr.08-56=10%, the smart start range will be from 0~40%.

Pr.08-55~08-58 are only valid when Pr.08-21 is set to 1.

Pr.08-58 is only valid when there is no source of line speed.

When start-up, it can set Pr.08-55 to 1 to prevent too long time for stable the dancer
(under loose material or out of Pr.08-56 setting).
Example: The PID control is only valid when setting Pr.08-57 and Pr.08-58 to make the
tension feedback reaches Pr.08-56 setting.

In unwind mode, when Pr.08-55 is set to 2, it allows to operate the motor in opposite
direction to tight the material automatically.
