EXHAUST FAN VFD CONFIGURATION
The sub-menu that contains these configurations is located at the
local display under Configuration
VFD2 Nominal Motor Volts (N.VLT)
This configuration defines the nominal motor voltage. This val-
ue 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 voltage greater
than the voltage supplied to the VFD input. Power to the VFD must
be cycled 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 Limita-
tions table (Table 29) if BP.CF=4
• the Supply Fan Motor Limitations table (Table 27) if
BP.CF=5
• the Optional VFD Power Exhaust Motor Limitations table
(Table 82) if BP.CF=3
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 val-
ue 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 for a change to this configuration to take effect.
