Our number one priority at Yaskawa Electric Corporation is to always keep the customerʼs

perspective in mind by leading the industry in meeting demands with uncompromising quality

and trust.

Our new CR700 was developed to further optimize cranes based on the concepts of Flexible,

Easy, Sustainable.

Yaskawa can now deliver the most ideal “answers”for various tasks related to the operation

of cranes, including brake sequences that have evolved from the technologies we have

developed to date.

Yaskawa has further improved the key functions for stable operations in our crane

sequence that has won the trust of our customers for over 30 years.

Reliable Crane Sequence

Brake Sequence

The break release command is judged and output in relation to the operation

frequency of the drive, output current, and amount of torque.

Brakes are released and applied while ensuring enough torque to maintain

the load during starts and stops to prevent load rollback.

Contact Positioning Function

When the Stop command is valid while a contact position

command is in effect for applications, such as transport

lines, the drive detects collision and stops operating if

the torque reference or output current are higher than the

standard value.

Quick positioning can be performed using this contact

positioning function.

Travel Limit Function

The limit sensor set in the allowable movement range

prevents over-traveling and overwinding.

Run Command Adjustment Function

Reliable movement during inching. Our system prevents

excessive current from flowing during lifting operations

performed immediately after lowering operations.

Note:This is only enabled when ramp to stop mode is selected.

Do not use this function with machines such as trucks with wheels

that may spin freely when there is a crash because the motor will not

be constrained, and the torque reference or output current will not

increase.

Yaskawa has enhanced dedicated crane functions for high-performance drives

using our collective technology to improve work efciency.

Shortened Takt Time & Improved Quality

Cargo Swing Suppression Function

Cargo swing during traverse motion can be reduced with

the built-in Cargo Swing Suppression function.

This enables cargo to be lowered without any swing,

which reduces takt times.

High-speed Operation at Light Loads

With this light-load, high-speed function, our drive

operates at optimal speed in accordance with the load.

High-speed operation can be performed when handling

light loads. This shortens the takt times when using long

lifting cranes, such as those used in constructions. ■Disabled

Yaskawa has tirelessly pursued ease of use, including initial setting functions for

crane motion axes, to improve operations and workability at all sites.

Improved Operations and Workability

Quick Deceleration Function

This function supports reverse phase braking (plugging)in

conventional crane operations that are not operated with drives.

The deceleration rate can be changed to quickly stop operation by

inputting a Run command in reverse to the current running direction

after a Stop command is received. This enables quick deceleration

near the target location even when using high speed operation.

Wire Length Detection

Information on the height of the hook that is not visible from

the operating room can be externally output using only the

drive.

Automatic Parameter Selection for Each Application

Application selection can be made for different types of crane

applications.

Selecting the appropriate application, such as lifting, traveling,

and transverse operation, will automatically enable only those

functions and disable unnecessary functions. This allows users

to easily set the optimal parameters for each application.

Lifting

Traveling

Traverse

CR700

Contactor Motor

3-Motor Switching Function

One drive can switch between and control motors with three axes for lifting/

lowering, travelling, and transverse operations. Our drive can support

individual brake sequences for each motor, so downtime during a drive failure

can also be reduced as a result of the ability of drives to act as substitutes for

other motors. Traditionally, one drive was needed for each motor. However,

one drive can switch between motors to reduce the number of drives needed.

Slope Prevention

High

precision control is performed in accordance with the operating conditions of machines to enable stable traveling and operation.

[Synchronization Control ]

Synchronization control is performed to prevent positional

deviation that can occur when lifting a load jointly with

two elevators using Closed Loop Vector Control. Separate

equipment and control to reduce slope are not required.

[Load Balancing Function ]

The load can be distributed evenly between drives without

the use of encoders.

Crane Maintenance Monitor

The monitor keeps a count of the number of brake

commands. This information is helpful in determining

brake maintenance schedules for inspecting system and

replacing parts.

Performance Life Monitors

With performance life monitors, the approximate maintenance

period of parts can be output as an alarm signal to notify users

in advance.

In addition, you can monitor the deterioration status of the

parts which can help you to make a maintenance plan easier.

Overload Detection Function

The drive restricts the operation of the crane (elevator)when the load exceeds a predetermined

upper limit value. The drive can be configured to display alarms and stop crane operation to

prevent operation with an overload that could lead to a dangerous situation.

Overtorque Detection Function

Detects an increased torque value when a load comes into contact with an object.

The drive stops the motor automatically to prevent machine malfunctions and increase safety.

Power supply

To minimize initial investment, the functions of the peripheral devices are

incorporated into the CR700. This eliminates the need for these devices, and saves

space, wiring, and labor.

Do You Want to Reduce Costs?

Note:Comparison with our conventional models.

In this case, a 400 V 110 kW model is used as an example.

Reductions in footprints vary depending on the capacity.

Built-in Braking Transistor and DC Reactor

Braking Transistor / DC Reactor Built-in

Harmonics resulting from built-in DC reactors are taken

into consideration. The braking transistor is also built in to

eliminate the need for a stand-alone braking unit.

This reduces a driveʼs footprint by approximately 45% in

comparison with the conventional drives, which enables the

design for more compact control panels.
