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.
