SUPPLY FAN VFD CONFIGURATION — The sub-menu
that contains these configurations is located at the local display
under ConfigurationS.VFD.
VFD1 Nominal Motor Volts (N.VLT) — This configuration
defines the nominal motor voltage. This value must equal the
value on the motor rating plate. This value sets the maximum
drive output voltage supplied to the motor.
NOTE: The VFD cannot supply the motor with a greater voltage
than the voltage supplied to the input of the VFD. Power to
the VFD must be cycled in order for a change to this configuration
to take effect.
VFD1 Nominal Motor Amps (N.AMP) — This configuration
defines the nominal motor current. This value must equal
the value defined in the Supply Fan Motor Limitations Table
26 or Table 27. Power to the VFD must be cycled in order for a
change to this configuration to take effect.
VFD1 Nominal Motor Freq (N.FRQ) — This configuration
defines the nominal motor frequency. This value must equal
the value on the motor rating plate. This value sets the frequency
at which the output voltage equals the Nominal Motor Volts
(N.VLT). Power to the VFD must be cycled in order for a
change to this configuration to take effect.
VFD1 Nominal Motor RPM (N.RPM) — This configuration
defines the nominal motor speed. This value must equal
the value on the motor rating plate. Power to the VFD must be
cycled in order for a change to this configuration to take effect.
VFD1 Nominal Motor HPwr (N.PWR) — This configuration
defines the nominal motor power. This value must equal
the value on the motor rating plate. Power to the VFD must be
cycled in order for a change to this configuration to take effect.
VFD1 Motor Direction (M.DIR) — This configuration sets
the direction of motor rotation. Motor direction change occurs
immediately upon a change to this configuration. Power to the
VFD need NOT be cycled for a change to this configuration to
take effect.
VFD1 Acceleration Time (ACCL) — This configuration sets
the acceleration time from zero to maximum output frequency.
Power to the VFD must be cycled in order for a change to this
configuration to take effect.
VFD1 Deceleration Time (DECL) — This configuration sets
the deceleration time from maximum output frequency to zero.
Power to the VFD must be cycled in order for a change to this
configuration to take effect.
VFD1 Switching Frequency (SW.FQ) — This configuration
sets the switching frequency for the drive. Power to the VFD
*This default is model number dependent.

must be cycled in order for a change to this configuration to
take effect.
VFD1 Type (TYPE) — This configuration sets the type of
VFD communication. This configuration should not be
changed without first consulting a Carrier service engineering
representative.
EXHAUST FAN VFD CONFIGURATION — The submenu
that contains these configurations is located at the local
display under ConfigurationE.VFD.
VFD2 Nominal Motor Volts (N.VLT) — This configuration
defines the nominal motor voltage. This value must equal the
value on the motor rating plate. This value sets the maximum
drive output voltage supplied to the motor.
NOTE: The VFD cannot supply the motor with a greater voltage
than the voltage supplied to the input of the VFD. Power to
the VFD must be cycled in order for a change to this configuration
to take effect.
VFD2 Nominal Motor Amps (N.AMP) — This configuration
defines the nominal motor current. This value must equal
the value defined in the High-Capacity Power Exhaust Systems
Motor Limitations Table 28. Power to the VFD must be cycled
in order for a change to this configuration to take effect.
VFD2 Nominal Motor Freq (N.FRQ) — This configuration
defines the nominal motor frequency. This value must equal
the value on the motor rating plate. This value sets the frequency
at which the output voltage equals the Nominal Motor Volts
(N.VLT). Power to the VFD must be cycled in order for a
change to this configuration to take effect.
VFD2 Nominal Motor RPM (N.RPM) — This configuration
defines the nominal motor speed. This value must equal
the value on the motor rating plate. Power to the VFD must be
cycled in order for a change to this configuration to take effect.
VFD2 Nominal Motor HPwr (N.PWR) — This configuration
defines the nominal motor power. This value must equal
the value on the motor rating plate. Power to the VFD must be
cycled in order for a change to this configuration to take effect.
VFD2 Motor Direction (M.DIR) — This configuration sets
the direction of motor rotation. Motor direction change occurs
immediately upon a change to this configuration. Power to the
VFD need NOT be cycled for a change to this configuration to
take effect.
VFD2 Acceleration Time (ACCL) — This configuration sets
the acceleration time from zero to maximum output frequency.
Power to the VFD must be cycled in order for a change to this
configuration to take effect.
