Motor #4 Max Output Voltage
Program ⇒ Motor Parameters ⇒ Motor Set #4
The Motor #3 Maximum Output Voltage is the Motor #4 output voltage at the Base Frequency (F178). Regardless of the programmed value, the output voltage cannot be higher than the input voltage.
The actual output voltage will be influenced by the input voltage of the ASD and the Supply Voltage Compensation setting (F307).
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.

Motor #4 Torque Boost
Program ⇒ Motor Parameters ⇒ Motor Set #4
The Motor #4 Torque Boost 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 (Motor #1 Torque Boost) 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.
