Motor #2 Max Output Voltage

Program Motor Parameters Motor Set #2

The Motor #2 Maximum Output Voltage is the Motor #2 output voltage at the Base Frequency (F170). 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 #2 are configured and selected. Motor set #2 may be selected by a properly configured input terminal.

Direct Access Number — F171

Parameter Type — Numerical

Factory Default — (ASD-dependent)

Changeable During Run — Yes

Minimum — 0.0

Maximum — 600.0

Units — Volts

Motor #2 Torque Boost

Program Motor Parameters Motor Set #2

The Motor #2 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 #2 Base Frequency setting (F170).

See parameter F016 (Motor #1 Torque Boost) 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.

Program Motor Parameters Motor Set #2

Parameter Type — Numerical

The Motor #2 Electronic Thermal Protection 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.

Minimum — 10.0

 

The unit of measurement for this parameter may be set to Amps (V/A) or it

Maximum — 100.0

 

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).

 

 

Electronic Thermal Protection settings (#1 – #4) will be displayed in Amps if

 

 

the EOI display units are set to V/A rather than %.

Program Motor Parameters Motor Set #3

Parameter Type — Numerical

The Motor #3 Base Frequency setting is the frequency at which the output

Changeable During Run — Yes

voltage of the ASD reaches its maximum setting. The Maximum Output

 

 

Voltage is set at F175.

Minimum — 25.0

 

This parameter is used only when the parameters for motor set #3 are

input terminal.

For proper motor operation, the Base Frequency should be set for the name- plated frequency of the motor.
