rewinding tension PID control.
1: Negative action. When the feedback
signal is less than the input quantity, the
output frequency of the drive drops to
make the PID reach balance. Such as
unwinding tension PID control.

1. After the drive starts, accelerate to the
initial PID value (F8.17) according to the
acceleration time. After running for a
period of time at this initial value (F8.18),
the PID starts the closed-loop adjustment
operation.
2. This function allows the closed-loop
adjustment to quickly enter the stable
phase.

indicates no detection)
When the feedback value is less than the
feedback loss detection value and the
feedback loss detection time has passed,
the drive reports a closed-loop feedback
loss fault (E020).
