Stroke limit protection: Integrate the functions of upper/lower limit and up/down deceleration limit to restrict the operation of the crane within the specified range, ensure safety while optimizing the shutdown mode and improving equipment efficiency.

Anti-sway function: Sensorless anti-sway control algorithm is used to realize the anti-sway control of various lifting equipment, which is simple to debug and has good adaptability

The standard anti-sway function can effectively suppress the shaking of goods during translation and improve work efficiency

The high-efficiency anti-roll function can effectively reduce the shaking of the goods during translation and improve work efficiency

Rope loosening protection: avoid safety accidents caused by high-speed lifting, malfunction of the speed lifting function and rope failure in the state of rope relaxation.

Smooth lifting: When running at high speed, when the hook lifts the load, the speed is automatically reduced, the hook is lifted smoothly, and the impact of the sudden load on the crane is reduced.

Zero servo: The motor is locked at zero speed, and the motor can remain locked at zero speed even if an external force in the forward/reverse direction is applied. When the brake fails, it can also drive the motor to control full-load hovering or controlled low-speed lowering to ensure safe use.

Light load speed increase: support constant power, stepped speed limit mode, according to the load situation to achieve the best running speed matching, shorten the crane operation cycle, improve the operation efficiency.

Warehouse protection: During the lifting process, after an abnormality such as hanging on other objects, the machine will be shut down in an emergency manner to ensure safety and improve efficiency

Safe torque shutdown (STO/SIL2): cut off the torque output when the motor stops to prevent the equipment from starting unexpectedly, which is reliable and safer; The inverter is uninterrupted, and can continue to monitor the system status and recover quickly.

Open-loop mode: simple ramp-up mode, ramp-up to the set frequency at light load, constant power mode ramp-up/speed limiting, step-by-step speed limiting.
Zero servo
In the closed-loop mode, when the shutdown is stopped, the load slippage will automatically enter the zero servo state, and the brake failure alarm will be output. In the event of a second-level fault, if the load slips, the fault will be automatically reset and enter the zero servo state, and the brake failure alarm will be output
Anti-sway and anti-sway of large and small cars
When the anti-sway function, the encoder needs to be installed for lifting, and the lifting and the large and small car frequency conversion are connected through analog AI or HDI, or are equipped with CAN master-slave card communication, so that the large and small car frequency conversion obtains the height value of real-time lifting and frequency conversion, and then combined with the built-in amplitude anti-sway algorithm, the output of the given frequency and acceleration and deceleration time, the large and small car frequency conversion accelerates or decelerates according to the start-stop command and the given frequency, which can eliminate the swing when the frequency conversion reaches steady state or stops.
According to the built-in amplitude reduction algorithm, it can run according to the set acceleration and deceleration time, and reduce the swing when the frequency conversion reaches steady state or stops.
The tower crane rotates to remove the eddy current
The built-in tower crane rotation and eddy current curve can adjust the frequency conversion acceleration in real time to make the torque more stable and ensure that the boom can be eliminated during operation and boom rebound and vibration during shutdown.
The tower crane is slewing and wind-resistant
In view of the problem that the rotation speed of the tower crane can not reach the given speed in the windy environment, the built-in rotary anti-wind algorithm overcomes the influence of wind factors on the rotation.
Loose rope protection (closed-loop mode only)
Upward loose rope protection: If the speed limit is detected as a loose rope state, the speed limit will be lifted when the load is overed or raised;
Downlink loose rope protection: If the loose rope state is detected, the inverter will report a fault or warning
Upper and lower limits
Restrict the crane to run within the specified range, and stop the emergency and alarm when it exceeds the range;
Up and down deceleration positions
When the deceleration signal is valid, the crane runs to the slow speed zone to limit the running speed.
One-way speed limit, e.g., when going up the slow zone, only the uplink speed limit
Load location
In closed-loop mode, the encoder is used to measure the load position
Master-slave control

Frequency drop with voltage
When the bus voltage is continuously low, reduce the given frequency to maintain the normal output torque of the inverter
Low voltage protection
When the bus voltage is instantaneously reduced or the power is off, the inverter stops quickly to ensure that there is no slippage, and the low voltage protection function is automatically restored when the bus voltage is restored
Low-speed operation protection
Low-speed overtime operation reports low-speed operation protection faults to avoid overheating and damage to the shaft-cooled motor during long-term operation
Overload protection
In closed-loop mode, when overloaded, the limit is raised upwards
Eddy current control
HDO outputs PWM waves, which directly control eddy currents
Hug brake feedback
When it is detected that the control signal of the brake is inconsistent with the feedback signal of the brake, it will be processed according to the state of the brake to ensure safety
Zero detection
The zero signal and the operating signal are mutually exclusive detections
Torque verification
Before the gate is released, the current or torque verification is carried out, and after the verification is successful, the operation is run to perform the release operation, and the torque verification fault is reported if the verification fails
Closed-loop/open-loop one-key switching
When the encoder fails, it can be switched to open-loop control mode through the terminal, and the application parameters can be switched at the same time, and it will respond when it stops and does not respond during operation.
Inching function
After receiving the inch command, the inverter can automatically start, run and stop according to the set value according to the given operating frequency and time. In this process, the brake can be loosened and closed normally under the control of the inverter, and ensure the smoothness, no slip hook and no abnormal movement in the starting and stopping process of the lifting machinery.
Smooth lifting
During high-speed lifting, the rapid speed limit is limited at the moment when the wire rope is straightened, so as to reduce the impact of the sudden load on the crane at the start of lifting
Set frequency anomaly protection
After the brake is opened, if the given frequency is lower than the set threshold, the abnormal fault or warning of the set frequency will be reported to avoid slipping due to insufficient output of low-speed operation under abnormal conditions
