Torque setting for
upward loose rope
protection
After loose rope protection is enabled, loose
rope detection is performed during crane
startup:
When the hoist runs upward and reaches

rope (Torque value > Loose rope torque
for downward running), normal
ACC/DEC is performed.
If the detected status is loose rope (Torque value
<= Loose rope torque
), the output
frequency is restricted to
