H9 ASD Installation and Operation Manual

Base Frequency 2

Program

Motor

Motor Set #2

The Base Frequency 2 setting is the frequency at which the output voltage of
the ASD reaches its maximum setting. The Base Frequency Voltage 2
parameter is set at

F171

.

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

).

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

Direct Access Number — F170

Parameter Type — Numerical

Factory Default — 60.0

Changeable During Run — Yes

Minimum — 25.0

Maximum — 299.0

Units — Hz

Base Frequency Voltage 2

Program

Motor

Motor Set #2

The Base Frequency Voltage 2 setting 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 (see

Table 5 on pg. 236

).

Direct Access Number — F171

Parameter Type — Numerical

Factory Default — (ASD-dependent)

Changeable During Run — Yes

Minimum — 50.0

Maximum — 660.0

Units — Volts

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

Parameter Type — Numerical

Factory Default — (ASD-dependent)

Changeable During Run — Yes

Minimum — 0.0

Maximum — 30.0

Units — %

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 %.
