In closed-loop mode, when overload occurs, upward lifting is
restricted.
The HDO outputs PWM waves to directly control vortex.
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.
The zero position signal and running signal are mutually
exclusive.
The VFD verifies the current or torque before brake release. The
VFD performs brake release when the verification succeeds, and
the VFD reports the verification fault when the verification fails.
The closed-loop control mode can be switched to the open-loop

control mode through terminals. When the encoder is faulty, the
open-loop control mode can be used. The switchover can get
response only in stopped state but not in running state.
After receiving a jogging command, the VFD can automatically
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.
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.
The I/O expansion card can receive motor temperature sensor
input (PT100, PT1000 and PTC).
