FEATURE 2: ROPE SLACK PREVENTION

• Avoids slackness of rope while placing the load
• Maintain tightness by rotating the drum in opposite direction
• Saves operating time
• Maintains Tensile strength of the rope
• Increases productivity

FEATURE 3: IMPACT STOP

• Drive senses any impact on the load and runs in lower speed for some time
• If the Run command is also removed, the drive will stop after monitoring torque reference
• Enhances safety

FEATURE 4: ZERO SPEED REGULATION

• Protection against mechanical brake failures during NO RUN command
• DC injection function provides required torque to hold the load
• Alarms the operator about mechanical brake failure.
• Enhances safety

FEATURE 5: SWIFT LIFT FUNCTION

• This function saves operating time of hoist during No- Load condition
• In built intelligent function provides dynamic speed control by load detection
• No external load sensor required
• Reduces cycle time
• Improves operational efficiency
• Increases productivity

FEATURE 6: TRAVEL LIMIT

• Prevent the load from travelling beyond a predefined point.
• Reduces physical damages due to uncontrolled operations.
• Multi-function digital inputs can be configured for forward or reverse travel limits.
• Provides the safety operation for the Long / cross travel.

FEATURE 7: COMPACT FOR BUILDING INTO MACHINE

• Smaller footprint drives ensure high compatibility.
• Panel provision in single girder cranes can be eliminated.

FEATURE 8: IMPROVED LOAD CONTROL

• Dedicated acceleration and deceleration parameters for smooth operation.
• Prevents shocks and load swings.
• Allows very accurate load positioning

FEATURE 9: HIGH AMBIENT TEMPERATURE OPERATION

• YASKAWA Drives are designed to operate upto 60ºC.
• Deration of the drive current above 50ºC.
• Drives are designed to operate in Humidity / Dust operation

FEATURE 10: MULTI SPEED REFERENCE

• Controls the crane on multi speeds, allowing customer to customize as per the requirement.
• Multiple speed references (17 speeds) are available.
• Provides smooth operation of crane and prevent jerk.

FEATURE 11: SAFE TORQUE OFF

• Provides a redundant hardware safety circuit
• Isolates the Drive and Motor during an Emergency with safe torque off function.
• Eliminates the need for external circuit for isolating the power.
• It allows easy maintenance of the motor / mechanical system without Drive power off.

FEATURE 12: SLIP COMPENSATION

• It ensures the speed regulation and accuracy in both hoisting directions.
• Reduces operating time.
• Improves speed response

FEATURE 13: MOTOR PHASE LOSS DETECTION

• Causes the drive to fault and commands the brake to set if an input or output phase loss occurs.
• Prevents over heating of motor due to output phase loss.

FEATURE 14: ADVANCED TORQUE CONTROL

• Ensures the full load torque at zero RPM
• Monitor over load & load loss and perform load sharing operation for multiple hoist cranes.
• Detects over torque and under torque condition

Ratings:

• 3ph 200V …. 240V +10%/-15%,0.4kW to 110kW
• 3ph 380V…. 480V +10%/-15%, 0.4kW to 300kW

A1000 for Winder is the solution to requirements of rewinder and unwinder systems. Being able to control induction and PM motors in open or closed loop,it allows precise winding of different materials such as textiles, paper, foils,wires and others.

Features & Benefits

• For line speeds up to 1500 m/min.
• Accurate motor control for smooth movements assures gentle winding and prevents stretch or material break, especially with sensitive materials
• Line tension control by direct torque control or by utilizing a dancer or tension cell
• Built in diameter calculator with memory function for easy start up after power off
• Static and dynamic friction compensation for precise tension control
• Excellent winding performance independent of line
  speed or diameter thanks to self-adapting PID, selfadapting motor control and inertia compensation
• Adjustable taper function optimizes tension depending on diameter
• Built in web break detection
• Application intelligence in the drive reduces requirements for external PLC and I/Os and improves winding performance
• Cost reduction, reliability improvement and lessmaintenance by doing away with external sensors for diameter or web break.
