When B0‑02 is set to 0, at zero
material speed, the unwinding
reel has no output and the
material is not tightened.
When B0‑02 is set to a value
between 0.1 m/min to 500.0 m/
min, under no‑load conditions or
if the material is in loose state, the
unwinding reel runs at the set
linear speed in the reverse
direction. At zero material speed,
the unwinding real maintains
output and the material is
tightened.
3.6.12PID Adjustment Limit
This function is valid only in closed‑loop mode (B0‑00 is set to 2 or 3).
