CR700
AC drives for crane applications
Enhanced dedicated crane functions
Continuous improvements of the key functions for crane applications has won the trust of our customers for over 30 years. The CR700 balances the hoist application in perfection. Made possible by innovative design advantages the CR700 crane drive helps you to lower initial investment for factory construction, supports you by increasing your productivity, lowers the efforts for daily maintenance and helps to reduce energy consumption.
Supreme features to build excellent crane solutions
These functions are our pride in crane. And these will support you in being unique. All the precious goods transported with the crane are handled with a lot of care. It's as smooth as handling containers with your own hands.
The outstanding master-follower position control of the CR700 is the key function for applications where multiple motors are not mechanically connected together but still require synchronous and precise position control. The speed and position control functions constantly monitor and compare the target and actual value of the motor shaft position and ensure super precise tandem operation.
- Master-follower position control
- Super precise tandem applications
- Speed controlled positioning
- No external controller needed, all control features built-in
- Automatic operation stop in case of position deviation
The anti-sway function improves the efficiency and safety in long and cross travel applications. Minimizing horizontal load sway allows for faster and easier positioning of the load. This intelligent function supports the crane operator and reduces maintenance costs by reducing wear.
- Reduces accidents and damage caused by load sway
- Works without external anti-sway sensors
- No motor encoder necessary
- Improves crane productivity and efficiency
- Applicable for long and cross travel
The light load function optimizes cycle times of the crane by adjusting the hoist speed according to the weight of the load. When a light load is detected, it automatically switches the operation speed to maximum. This minimizes hoist operating time and increases productivity.
- Detects load
- Automatically adjusts operation speed
- Shorter cycle time
- Increases hoist efficiency

Even more useful features for your crane application
With the following features and functions of the CR700, it's easier and more convenient than ever to build your crane application - and to deliver outstanding solutions for your own customers.
The CR700 is optimized to combine the required power gained from all travel drives to overcome friction forces during travel in Open Loop Vector Control. This feature solves the problem of overloading one motor due to an unbalanced load and minimizes the risk of mechanical wear by distributing the load impact across multiple drives.
- Reduces costs and the risk of encoder failure
- Prevents unbalanced load and motor overload
- Reduces mechanical friction and crane wear
- Smooth and precise travel acceleration

In applications with long hoisting distance, the rope length detection function supports the crane operator to work more safely by sharing the information about actual load position.
- Prevents operation range mismatch
- Monitors hook and load position
- Improves hoist safety
- Travel limit monitor

Preventive maintenance monitors increase crane safety and product availability. All drive lifetime monitors can be easily accessed via keypad operator or network communication options. These comprehensive service functions support you to schedule preventive maintenance before fault happens.
- Number of run commands
- Drive and cooling fan operation time
- Capacitor, IGBT and SoftCharge relay lifetime
- Drive temperature
- Actual operation peak load

The programmable counter monitors the number of run commands and brake release commands and outputs an alarm once the number reaches the operation value. This supports the maintenance team to schedule preventive maintenance of the mechanical brake.
- Preventive maintenance
- Reduce brake wear
- Increase brake safety and reliability
