After loose rope protection is enabled, loose rope
detection is performed during hoist startup:
When the hoist runs upward and reaches P93.26,
torque detection is performed after the delay
P93.28. If the detected status is non loose rope
(Torque value > Loose rope torque P93.24 or
P93.25 for downward running), normal ACC/DEC
is performed.
If the detected status is loose rope (Torque value
<= Loose rope torque P93.24), the output
frequency is restricted to P93.26 within P93.27.
If load holding, (Torque value) > (Loose rope
torque P93.24+2%), is detected within P93.27,
normal ACC/DEC is performed from this time.
If the time exceeds P93.27, normal ACC/DEC is
performed from this time.
P93.24 can be set with the reference to the
autotuning result P93.33. Generally, the value of
