100 H9 ASD Installation and Operation Manual

Base Frequency 4

Program ⇒ Motor ⇒ Motor Set #4
The Base Frequency 4 setting is the frequenc y at which the output voltage of
the ASD reaches its maximum setting. The Base Frequency Voltage 4
parameter is set at F179.
This parameter is use d only when the param eters for motor set #4 are
configured and selected. Motor set #4 may be selected by a properl y co n f i gu r e d
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.

Changeable During Run — Yes
Minimum — 25.00
Maximum — 299.0
Units — Hz

Base Frequency Voltage 4

Program ⇒ Motor ⇒ Motor Set #4
The Base Frequency Voltage 4 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 use d only when the param eters for motor set #4 are
configured and selected. Motor set #4 may be selected by a properl y co n f i gu r e d
input terminal (see Table 5 on pg. 236 ).
Direct Access Number — F179
Parameter Type — Numeri cal
Factory Default — (ASD-dependent)
Changeable During Run — Yes
Minimum — 50.0
Maximum — 660.0
Units — Volts

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 increasi ng the output voltage at frequencies
below ½ of the #4 Base Frequency setting (F178).
See parameter F016 (Manual Tor que Boost 1) for an explanation of torque
boost.
This parameter is use d only when the param eters 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 ).
Direct Access Number — F180
Parameter Type — Numeri cal
Factory Default — (ASD-dependent)
Changeable During Run — Yes
Minimum — 0.0
Maximum — 30.0

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 AS D or as the FLA of th e 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 4 Overload Protection Level setting will be displayed in Amps if
the EOI display units are set to A/V ra th e r th an %.
