EXHAUST FAN VFD CONFIGURATION
The submenu that contains these configurations is located at
the local display under

E.VFD
.
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 greater volt
-
age than the voltage supplied to the input of the VFD. Power to
the VFD must be cycled in order for a change to this configura
-
tion to take effect.
VFD2 Nominal Motor Amps (N.AMP)
This configuration defines the nominal motor current. This val
-
ue must equal the value defined in:
• the High-Capacity Power Exhaust Systems Motor Limita
-
tions table (Table 22) if
BP.CF
=4
• the Supply Fan Motor Limitations table (Table 21) if
BP.CF
=5
• the Optional VFD Power Exhaust Motor Limitations table
(Table 68) 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
value must equal the value on the motor rating plate. This val
-
ue sets the frequency at which the output voltage equals the
Nominal Motor Volts (
N.VLT
). Power to the VFD must be cy
-
cled 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 val
-
ue 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 val
-
ue 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.
