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.

Pr.08-59 is only valid when Pr.08-39 is not set to 0 and Pr.08-42 is set to 0.
When the broken belt detection is enabled, line speed is higher than Pr.08-60, allowance
difference of reel diameter of broken belt detection exceeds Pr.08-61 and detection time of
broken belt exceeds Pr.08-62, the broken belt occurs. When the broken belt occurs, it will
display “bEb” with free running. It can be used with the multi-function output terminal setting 46
for broken belt detection.
