input terminal (see Table 5 on pg. 236).
For proper motor operation, the Base Frequency should be set for the name-
plated frequency of the motor.

This parameter is used only when the parameters for motor set #2 are configured and selected. Motor set #2 may be selected by a properly configured input terminal (see Table 5 on pg. 236).

Manual Torque Boost 2

Program ⇒ Motor ⇒ Motor Set #2

The Manual Torque Boost 2 function is used to increase the low frequency torque for high inertia loads by increasing the output voltage at frequencies below ½ of the Base Frequency 2 setting (F170).

See parameter F016 (Manual Torque Boost 1) for an explanation of torque boost.

This parameter is used only when the parameters for motor set #2 are configured and selected. Motor set #2 may be selected by a properly configured input terminal (see Table 5 on pg. 236).

Direct Access Number — F172

Motor Overload Protection Level 2

Program ⇒ Motor ⇒ Motor Set #2

The Motor 2 Overload Protection Level parameter specifies the motor overload current level for motor set #2. This value is entered as either a percentage of the full load rating of the ASD or as the FLA of the motor.

The unit of measurement for this parameter may be set to Amps (A/V) or it may be set as a percentage of the ASD rating. The name-plated FLA of the motor may be entered directly when Amps is selected as the unit of measurement (see F701 to change the display unit).

The Motor 2 Overload Protection Level setting will be displayed in Amps if the EOI display units are set to A/V rather than %.

Direct Access Number — F173

Parameter Type — Numerical

Factory Default — 100

Changeable During Run — Yes

Minimum — 10

Maximum — 100
