4.14.2 Auto Torque Boost
Set DRV-
15 to ‘Auto 1’ or ‘Auto 2’ to select the type of torque boost. While manual torque
boost adjusts the inverter output based on the setting values regardless of the type of load
used in the operation, auto torque boost enables the inverter to automatically calculate the
amount of output voltage required for torque boost based on the entered motor parameters.
Because auto torque boost requires motor-related parameters such as stator resistance,
inductance, and no-load current, auto tuning (BAS-20) has to be performed before auto
torque boost can be configured. Similarly to manual torque boost, configure auto torque
boost while running a load that requires high starting torque, such as lift-type loads. Refer to
5.21 Auto Tuning on page 210.
4.14.3 Auto Torque Boost 2 (No Motor Parameter Tuning
Required)
By adjusting the auto torque boost voltage gain set at DRV-15 (ATB Volt Gain), automatic
torque boost may be operated without tuning the motor-related parameter values. The
DRV-15 (ATB Volt Gain) value is used to adjust the amount of compensation required for
each load. It prevents stalls or overcurrent fault trips at start up.
