1: Mode 2. The VFD outputs the loose rope
protection alarm (A-SL), changes the direction,
and runs upward at the frequency specified by
P93.31, and the VFD runs downward only when
the time specified by
loose rope status disappears.
P93.30 setting range: 0–20.00s
P93.31 setting range: 1.00Hz–10.00Hz
Note: P93.30 must be greater than the sum of
the time taken to decelerate from
and the time taken to accelerate from 0Hz to
P93.31.
The autotuning procedure is as follows:
Step 1 Put the hook on the ground and loosen
the rope.
Step 2 Set P93.19=1 (or
running).
Step 3 Push the operating lever to step-2 speed
(higher than 10Hz), which is held at least 1s in
the loose rope state after the frequency is stable
(to autotune stable frequency torque).
Step 4 Stop the device and check the autotuning
result. If P93.32 (or P93.33
