More DocumentsIf your business has a crane or manufactures cranes, Nam Phuong Viet thinks you should know about the Yaskawa CR700 Inverter product line. CR700 is an advanced inverter line, researched and developed with specialized features to help solve problems during crane operation.
Let’s see what special features it has!
Yaskawa CR700 Inverter – Optimal solution for lifting applications
Master-follower position control function
This is probably a function that not all inverters on the market have. The Master-Follower function allows the Yaskawa CR700 inverter to operate synchronously and accurately control the speed and position of the motor. If the load deviates slightly, the system will immediately stop working.
This is an extremely useful feature in cases such as lifting a heavy-duty bridge connecting two buildings, building a bridge across a river, lifting goods requiring a combination of two inverters and two motors…
Anti-sway function
The problem of vibration during lifting can lead to serious consequences if not handled properly. With the Yaskawa CR700 inverter, you no longer have to worry about that problem. The CR700 is integrated with an anti-sway function to help position the load faster and more accurately. This minimizes the situation of horizontal load shaking when the load is moved over a long distance or diagonally.
Light load function
The Yaskawa CR700 inverter can adjust the lifting speed according to the weight of the load. When a light load is detected, the device automatically switches the operating speed to the maximum level. Thereby helping to improve lifting efficiency.
Encoder-free load balancing function
The Yaskawa CR700 inverter can synchronize motor speed and torque control in open-loop vector control mode. This feature solves the problem of motor overload due to an unbalanced load and minimizes the risk of mechanical wear by distributing the load impact force across multiple inverters.
Cable length detection function
In applications with long lifting distances, the Yaskawa CR700 inverter’s cable length detection function helps crane operators work more safely by sharing information about the actual load position. This helps:
- Prevent mismatched operating ranges
- Monitor hook and load positions
- Improve hoist safety
- Travel limit display
Screen integrated with function to monitor the life of components and accessories
All Yasskawa CR700 drive displays can be accessed via the keypad or network. This feature helps operators schedule preventive maintenance before a failure occurs:
- Number of Runs
- Cooling Fan and Controller Runtime
- Capacitor, IGBT, and SoftCharge Relay Lifespan
- Controller Temperature
- Actual Peak Load
Thereby increasing the safety of the crane and the availability of the product.
Integrated trip limit sensor
A trip limit sensor connected to the controller prevents the motor from overspeeding and winding outside the defined working area.
- Limit the working area of the load hook
- Equipped with anti-collision features
Equipped with a programmable counter that tracks the number of running commands and brake release commands
The Yaskawa CR700 inverter has a programmable counter that tracks the number of running and brake release commands. It also issues a warning when the command number reaches the operating value. Helps:
- Schedule Brake Maintenance
- Reduce Brake Wear
- Increase Brake Safety and Reliability
Other outstanding features of the Yaskawa CR700 inverter
The Yaskawa CR700 inverter has a friendly, intuitive interface
The Yaskawa CR700 inverter offers a user-friendly programming experience with an intuitively designed keypad. The self-guided navigation menu and startup wizard make programming and setup faster and easier than ever.
With DriveWizard Mobile, your smartphone or tablet can easily manage and control drives.
In addition, CR700 is also equipped with many user support utilities such as:
- Real-time clock
- Automatic parameter backup function
- Advanced keyboard and start-up wizard
- Parameter setting for up to 4 motors
- Copy function
- Micro SD storage
- High-resolution display
- Optional LCD keyboard with Bluetooth connection
Yaskawa CR700 – Super energy-saving inverter
In addition to crane-specific features, Yaskawa inverters offer solutions to help businesses save energy effectively.
By combining the CR700 inverter with other Yaskawa inverters, such as the D1000 inverter and R1000 inverter, your business can save up to 35 – 40% of energy consumption.
The Yaskawa CR700 inverter is easy to install and monitor
With DriveWizard ® Mobile software, you can set parameters and control the Yaskawa CR700 drive, backing up data on your smartphone or in the YASKAWA Drive Cloud.
The software provides intuitive parameter editing tasks with help and search functions, creating favorite parameter lists, parameter backup/verification, etc. In addition, the software also integrates an 8-channel oscilloscope with comprehensive triggering and data analysis functions, as well as a setup wizard for quick setup without knowing about menus and parameters.
Helps you install the inverter quickly and monitor the operation conveniently.
