Frequency (F178). Regardless of the programmed value, the output voltage | |||
|
| ||
cannot be higher than the input voltage. | Minimum — 50.0 |

Manual Torque Boost 4
Program ⇒ Motor ⇒ Motor Set #4
The Manual Torque Boost 4 function is used to increase the low frequency torque for high inertia loads by increasing the output voltage at frequencies below ½ of the #4 Base Frequency setting (F178).
See parameter F016 (Manual Torque Boost 1) for an explanation of torque boost.
This parameter is used only when the parameters for motor set #4 are configured and selected. Motor set #4 may be selected by a properly configured input terminal (see Table 5 on pg. 236).

Motor Overload Protection Level 4
Program ⇒ Motor ⇒ Motor Set #4
The Motor 4 Overload Protection Level parameter specifies the motor overload current level for motor set #4. 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 4 Overload Protection Level setting will be displayed in Amps if the EOI display units are set to A/V rather than %.
