Heavy Duty Rating

The overload tolerance is 150% of the rated output current for 60 seconds.

Normal Duty Rating

The overload tolerance is 110% of the rated output current for 60 seconds.

There are two types of load ratings for this product depending on the load characteristics of the application: Heavy Duty Rating (HD) and Normal Duty Rating (ND).

The drive rated output current, overload tolerance, and acceleration stall prevention level change when the duty rating changes. Set the drive to agree with the duty rating of the selected drive capacity. In HD, the tolerance is 150% overload for 60 seconds. In ND, the tolerance is 110% overload for 60 seconds. The rated output current for ND drives is higher than the rated output current for HD drives. Refer to “Model-Specific Specifications“ for more information about the rated output current.

Load Characteristics

Application

A high overload tolerance is necessary during start up, acceleration, deceleration, and equivalent conditions.

  • Extruder

  • Conveyor

  • Cranes and hoists

  • Constant torque or high overload capacity are necessary.

Overload tolerance is not necessary.

  • Fan

  • Pump

  • Blower

Note:

  • Set the stall prevention level during acceleration with L3-02 and the stall prevention level during run with L3-06.

  • Changing C6-01 also changes the maximum capacity of applicable drive motors. The drive automatically changes the setting values E2-xx and E4-xx to applicable values. The drive also automatically changes these parameters that depend on motor output:

    • b8-04 [Energy Saving Coefficient Value]

    • C5-17 [Motor Inertia]

    • C5-37 [Motor 2 Inertia]

    • L2-03 [Minimum Baseblock Time]

    • L3-24 [Motor Accel Time @ Rated Torque]

    • n5-02 [Motor Inertia Acceleration Time]
