SOME OF THE ADVANTAGES OF STEPLESS SPEED CONTROL USING VVVF DRIVES ARE AS LISTED BELOW:

• ALL MOTIONS CAN BE OPERATED FROM 10% TO 100% OF THE SPEED.
• ALL MOTOR PROTECTIONS ARE PROVIDED IN THE DRIVE.SOME OF THE PROTECTIONS ARE AS LISTED BELOW.
  • OVER LOAD OR OVER CURRENT PROTECTION
  • SINGLE PHASING PROTECTION.(CURRENT SENSING)
  • OVER TORQUE PROTECTION.
  • PHASE SEQUENCE PROTECTION.
• MINIMIZED LOAD SWING.
• EXCELLENT LOAD HANDLING CAPABILITIES.
• NO CRANE SKEW.
• OPTIMISED LOAD CURRENT DEPENDING ON THE LOAD BEING HANDLED. 
• OVERALL POWER CONSUMED IS DEPENDANT ON THE LOAD CARRIED. I.E IF YOU HAVE TAKEN A 50T CRANE AND HANDLING 5T LOAD WITH IT, THE POWER CONSUMED WILL BE CORRESPONDING TO 5T ONLY.
• SOFT START AND SOFT STOP REDUCING STRESSES ON CRANE  MECHANICALS, MOTORS AND BRAKES.
• ENHANCED MECH BRAKE LIFE AS IT IS ONLY USED TO HOLD THE LOAD, STOPPING IS DONE ELECTRICALLY.
•  ALMOST UNITY POWER FACTOR.
