Delta VFD-VE - 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

Chapter 4 Parameters
4-153
 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.
