GX9 ASD Installation and Operation Manual 133
Base Frequency Voltage 1
Program Motor Motor Set 1
The Base Frequency Voltage 1 setting is the Motor 1 output voltage at the
Base Frequency (F014). 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 Correction setting (F307).
This parameter is used only when the parameters for Motor Set 1 are
configured and selected. Motor Set 1 may be selected by a properly configured
input terminal (see Table 8 on pg. 217).
Direct Access Number — F306
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — Yes
Minimum — 0.0
Maximum — 700.0
Units — Volts
Supply Voltage Correction
Program Protection Base Frequency Voltage
This parameter Enables/Disables the Voltage Compensation function.
When Enabled, this function provides a constant V/f ratio during periods of
input voltage fluctuations.
Settings:
0 — Disabled
1 — Supply Voltage Compensation
2 — Output Voltage Limitation
3 — Supply Voltage Compensation w/Output Voltage Limitation
Direct Access Number — F307
Parameter Type — Selection List
Factory Default — Supply Voltage
Compensation
Changeable During Run — No
Dynamic Braking Resistance
Program Protection Dynamic Braking
This parameter is used to input the resistive value of the Dynamic Braking
Resistor being used.
Light-duty and heavy-duty resistors vary from a few ohms to several hundred
ohms. The appropriate resistance size will be typeform- and
application-
specific.
See the section titled Dynamic Braking Resistor Requirements on pg. 6 for
more information on using the DBR system and for assistance in selecting the
appropriate resistor for a given application.
Note: Using a resistor value that is too low may result in system
damage.
Direct Access Number — F308
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 1.0
Maximum — 1000.0
Units —
Continuous Dynamic Braking Capacity
Program Protection Dynamic Braking
This parameter is used to input the wattage of the Dynamic Braking Resistor.
See the section titled Dynamic Braking Resistor Requirements on pg. 6 for
more information on using the DBR system.
Note: Using a resistor with a wattage rating that is too low may result
in system damage.
Direct Access Number — F309
Parameter Type — Numerical
Factory Default — (ASD-Dependent)
Changeable During Run — No
Minimum — 0.01
Maximum — 600.00
Units — kW
