Audited Supplier Based on years of experience in the industry, CH310 series features excellent torque control, reliable brake control timing, speed and torque monitoring, power optimization, position processing, intelligent deceleration and more, fully ensuring the safety, reliability and high efficiency of the hoisting appliances in harbor, ships, marine engineering, and mining.
It can realize 200% of the rated torque output at 0.0Hz, and stable operation with load at the ultra-low speed under 0.01Hz. High torque output for starting ensures smooth ascending/descending process without sliding.
Stable torque output in torque control mode with linearity tolerance within 3% or less.
The brake will act only when the two conditions of release/apply frequency and release/apply torque are satisfied at the same time to ensure smooth lifting and stopping without slipping.
Speed is automatically lowered to tighten the wire rope slowly when goods are raised at high speed and the rope is slack, so as to prevent overstretching of the wire rope due to excessive tension, prolonging its service life.
When a sudden increase in load torque is detected during the hoisting process (hanging by a foreign object or being held by an obstacle), an alarm is issued and operation is stopped.
Master-slave sync control function: when the dual hoisting mechanism lifts one object at the same time, the master-slave sync control function can ensure that it is lifted synchronously to ensure safety.
Built-in constant power control algorithm (speed change with load ) automatically matches the best running speed according to the current lifting weight, 1-2 times up of the working efficiency.
Open/closed loop anti-swing control algorithm with simple debugging and good adaptability reduces hook swaying caused by inertial shock from the cart and trolley and goods swing during translation to keep efficiency and safety.
Turn it on or off by the switch.
Master-slave sync control function: when the double hoisting mechanism lifts one object at the same time, the master-slave sync control function can ensure that it is lifted synchronously to ensure safety.
Real-time position correction is adopted for master and slave for traveling mechanisms with large spans to realize synchronization control.
Low-speed slewing is smooth without "stuttering" for quick positioning.
Quick stop with reverse gear (Slewing)
Quick stop can be realized by the reverse gear during slewing without boom shake and rebounce.(for slewing mechanism of tower cranes).
Grab sync control
CH310 AC drives automatically control the grab with a single closing command, the system will close the grab automatically, then adjust tension of the supporting rope and the clamping rope until they are balanced.
Similarly, the clamping of the grab only needs a command, and the system automatically completes it. Its status is determined by the absolute rope difference between the clamping and the supporting ropes, and the deceleration zone is automatically set up to prevent the sudden impact.
Wide tooth surface for heat dissipa-tion and high air speed to ensure no derating under high tempera-ture for full power.
The allowable fluctuation range of input voltage is ±20% of the standard rated voltage to avoid its influence effectively and at the same time, the output is still qualified under harsh grids.
150% of the rated current for 1 minute, 180% for 10 seconds, and 200% for 3s.
The drive reduces the operating frequency when the supply voltage decreases to keep working.
Power(kW)
0.75kW~110kW standard with braking units.
45kW~110kW optional for built-in reactors.
132kW (incl.) standard with DC reactors.
It realizes all-round protection for the drives and peripheral devices including short-circuit protection to ground, internal buffer relay protection, fan protection, external 24V DC short-circuit protection, motor overload protection and more.
CH310 series supports several encoder interfaces of collec-tor signal, differential signal, and resolver signal for closed-loop vector control.
A variety of expansion interfaces are available for customization.
CH310 control board retains two SPI high-speed channels for the external expansions, and its type and parameters are automat-ically recognized.
Intelligent terminals with high positioning accuracy in small size with easy installation. GPRS and GSM dual-mode communica-tions ensures stable operation and reliable performance. And online monitoring, and remote fault diagnosis are realized through the remote monitoring module, offering customers with a wider range of value-added services.
Drive can perform simple logic instead of PLC with the widely used MELSEC programmable controller program development environment integrated with general and compre-hensive function blocks.
Applications:Rubber tyre gantry cranes, rail-mounted cranes, gantry cranes, general cranes, tower cranes etc.
