Base Frequency Voltage 3 | Direct Access Number — | F175 | |
Program ⇒ Motor ⇒ Motor Set #3 | Parameter Type — Numerical | ||
The Base Frequency Voltage 3 setting is the Motor #3 output voltage at the | Factory Default — | ||

Base Frequency (F174). Regardless of the programmed value, the output | |||
|
| ||
voltage cannot be higher than the input voltage. | Minimum — 50.0 |

Manual Torque Boost 3
Program ⇒ Motor ⇒ Motor Set #3
The Manual Torque Boost 3 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 3 setting (F174).
See parameter F016 (Manual Torque Boost 1) for an explanation of torque boost.
This parameter is used only when the parameters for motor set #3 are configured and selected. Motor set #3 may be selected by a properly configured input terminal (see Table 5 on pg. 236).

Motor Overload Protection Level 3
Program ⇒ Motor ⇒ Motor Set #3
The Motor 3 Overload Protection Level parameter specifies the motor overload current level for motor set #3. 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
The Motor 3 Overload Protection Level setting will be displayed in Amps if the EOI display units are set to A/V rather than %.
