start, run, and stop at the preset running frequency and time
according to the settings. During the process, the brake can be
normally opened or closed under the control of VFD, ensuring
the stability without hook slip or exception when the crane starts
or stops.
In high-speed lifting mode, the high speed is limited at the
moment of steel rope straightening, reducing the impact caused
by the sudden load to the crane at the lifting start.
In the process of upward lifting, if the hook is abnormally hung, it
can quickly stop the machine and instantly eliminate the potential
safety hazards.
If the set frequency is lower than the threshold after the brake is
opened, the VFD reports the set frequency exception, which
prevents slip caused by insufficient force at low speed.
An I/O expansion card can receive the input from a motor
temperature sensor (PT100, PT1000, or PTC); at the same time,
AI analog can also receive the input from a motor temperature
sensor (PT100, PT1000, KTY84, or PTC), for motor overheating
protection.
