11 Drive Control, Duty Modes, and Programming
◆
Drive Duty Modes
The drive has two duty modes from which to select for the application: Heavy Duty (HD) and Normal Duty (ND).
• The input power kVA
• The maximum applicable motor output
• The rated input current
• The rated output capacity
• The rated output current
Note:
The reference for the parameter set as a percentage of the drive rated output current is the rated output current of HD/ND.
Refer to
Table 11.1
for information about the differences between HD and ND ratings.

Auto-Tuning
WARNING
Crush Hazard. Rotational Auto-Tuning rotates the motor at 50% or more of the motor rated frequency. Make sure
that there are no issues related to safety in the area around the drive and motor. Increased motor frequency can cause serious
injury or death.
WARNING
Sudden Movement Hazard. Before you do Rotational Auto-Tuning, disconnect the load from the motor. The load
can move suddenly and cause serious injury or death.
Auto-Tuning automatically sets parameters on the drive connected to the motor. You must input some parameters
individually during Auto-Tuning.
1. Select [Auto-Tuning] from the main menu to select the Auto-Tuning Mode.
2. Use the information in
3. Push
to start Auto-Tuning.
Refer to the Technical Reference for more information about Auto-Tuning.

Application Conditions and Benefits
Recommended tuning mode for the most accurate results. Select this tuning mode when:
• You can decouple the motor from the load.
• You cannot decouple the motor from the load, but the motor load is less than 30%.
Automatically calculates motor parameters for vector control. Select this tuning mode when:
• You cannot decouple the motor from the load.
• The motor test report data is not available.
Select this tuning mode when:
• The drive and motor capacities are different.
• The drive is in V/f Control.
• You have replaced the drive and motor.
