Function
Specification
mode)
Downward loose rope protection: If the loose rope state is
detected, the VFD reports a fault or alarm.
Upward or
downward
position limit
The function is used to limit the hoist to run within the specified
range. The VFD enables emergency stop and reports an alarm
once the range is exceeded.
Upward or
downward DEC
position
When the deceleration signal is valid, the running speed of the
hoist is limited once the hoist runs within the slow speed area.
The function also features uni-directional speed limit. For
example, only the upward running speed is limited when the hoist
runs within the upward slow speed area.
Load position
In closed-loop mode, the encoder is used to obtain load position
information.
Master/slave
control
Including power balance and speed synchronization between the
master and slave.
Hoisting
application macro
Including lifting, horizontal moving, construction hoist, and tower
crane rotating, and user-defined application macros.
Lifting and
horizontal moving
switchover
Three groups of motor parameters, control modes, and
application macros can be switched.
Frequency
derating with
voltage
When the bus voltage is continuously low, the reference
frequency is decreased to keep the normal output torque of VFD.
Low voltage
protection
When the bus voltage decrease transiently or the VFD quickly
stops due to power outage, the function is used to ensure the
hook does not slip. The low voltage protection function is
automatically disabled once the bus voltage restores to the
normal state.
Low-speed
running protection
The VFD reports the low-speed running protection fault when the
low-speed running time exceeds the allowed time. The prevents
the axial cooling motor from being damaged due to overheating
caused by long-time running.
Overload
protection
In closed-loop mode, when overload occurs, upward lifting is
restricted.
Turbulence
control
HDO outputs PWM waves to directly control turbulence.
Brake feedback
When the brake control signal is inconsistent with the brake
feedback signal, the VFD handles the inconsistency according to
the brake status to ensure safety.
