Our top priority at Yaskawa is to always keep the customer perspective in mind. By directing this focus to our user-friendly frequency converters, we offer the highest level of quality and product reliability. Our CR700 crane drive is designed to further optimize crane applications based on the concepts: Flexible, Easy, Sustainable.
Enhanced special crane functions
Especially for crane applications, Yaskawa introduces the CR700. For these demanding applications, customers worldwide have trusted Yaskawa reliability for more than 30 years. Smart innovations – such as the advanced anti-sway function – increase productivity. In addition, energy consumption is significantly lower and maintenance is kept to a minimum. In short, with the new CR700 you also bring your crane application into perfect balance.
Excellent features for building superior crane solutions
These features are what we pride ourselves on in the crane drive industry. And they will help you stand out. All valuable goods that you transport with the crane are handled with great care.
The CR700's excellent master-follower position control is the key feature for applications where multiple motors are not mechanically connected, but synchronous and precise position control is still required. The speed and position control functions continuously monitor and compare the target value and the actual value of the motor shaft position, ensuring super-precise tandem operation.
• Master-follower position arrangement
• High precision tandem applications
• Speed controlled positioning
• No external controller required, all control functions built in
• Automatic operating stop in case of position deviation
The anti-sway function improves efficiency and safety in long and transverse travel applications. By minimizing the horizontal sway of the load, the load can be positioned faster and easier. This intelligent function supports the crane operator and reduces maintenance costs through less wear.
• Reduces accidents and damage caused by swinging loads
• Works without external anti-sway sensors
• No motor encoder required
• Improves crane productivity and efficiency
• Suitable for long and cross transports
The light load function optimizes the crane's cycle times by adjusting the hoist speed to the weight of the load. When a light load is detected, it automatically switches the working speed to maximum. This minimizes hoist operating time and increases productivity.
• Detects load
• Automatic adjustment of the working speed
• Shorter cycle time
• Increases hoist efficiency
Extreme conditions
Designed for 10 years of maintenance-free operation, the CR700 is ruggedly built to withstand even harsh and demanding conditions.
Extra protection as standard
Standard coated printed circuit boards protect the electronics from dust or moisture and ensure reliable operation even in harsh environments (IEC 60723-3-3, 3C2, 3S2).
Wide ambient temperature range
CR700 drives can be safely operated in ambient temperatures ranging from -10°C to 60°C. In environments with conditions up to 50°C, derating is not required.
Quick and easy installation
The CR700 offers a user programming experience with an intuitively designed keypad and user interface. Self-guided navigation menus and startup wizards make programming and setup faster and easier than ever. With DriveWizard Mobile, the CR700 can be easily managed and controlled from your smartphone or tablet.
