8.3 VFD – Advanced Setup
Group
VFD-4: Auto Bypass
Auto Bypass
4) Disabled 0 - Disabled
1 - On VFD Fault
2 - Bypass Comm Loss
3 - VFD Fault & Bypass
Comm Loss
Default: Disabled
If set to “On VFD Fault” and VFD trips, the VFD
bypass will start if run command is present. If set
to “Bypass Comm Loss” and VFD communication
is not present, the bypass will start. If set to both,
bypass starts when either VFD ‐ Bypass comms
are lost or VFD is in Fault mode.
VFD-6: Damper Control
Damper Control
6) Disabled 0 - Disabled
1 – Enabled
Default: (0) Disabled
Enables Damper or Lubrication Mode. If start
command is received, VFD will provide 24VDC,
0.5A to a damper motor and after Damper delay
or when DSW is closed VFD will start motor.
VFD-7: Damper Delay
Damper Delay
7) 120s Min: 0s
Max: 6000s
Default: 120s
1. No damper limit switch. After start
command is received, VFD will provide
power to a damper motor and after Damper
delay it will start the motor. There is no
damper fault by limit switch.
2. If a digital input is set to damper SW and VFD
receives run command, VFD provides power
to damper motor and after limit SW is
closed, it will start a motor. If SW is not
closed within time delay, VFD will trip on
damper fault.
Skip Frequencies
There are three sets of Skip Frequency pairs of
parameters that let you Enable or Disable or set
Low and High value for each set. The description
below applies to each set respectively:

Disabled: Skip frequency is disabled

Enabled: Skip frequency allows you to skip
from the VFD reference short frequency
range of system resonant frequencies.
If the speed reference given digitally from a
keypad or communication is set to a value in the
skip zone, the VFD will run at Low Skip Hz until
the speed command is at or above High Skip Hz.
Then the VFD speed reference will jump from
Low to High Skip Hz and the VFD output
frequency will ramped up based on the
acceleration time. On each skip zone, the only
condition we need to maintain is that the Skip
High should be at least 1Hz greater than Skip
Low. Between zones it is not a problem if the 2
nd
Skip Zone is set below or overlapping the 1
st
one.

Low Frequency (Low frequency of the
resonance skip zone) : If analog signal or
communication is used for speed reference,
the VFD will continue to run at the Low Skip
Frequency until the signal value is at or
greater than the High Skip Frequency. Then
the VFD will ramp ‐ up from Low to High skip
Hz based on the acceleration time. Range
0Hz to PRIMARY ‐ 7 (Max Frequency).

High Frequency (High frequency of the
resonance skip zone ): Range ‐ Low
Frequency for this Skip Frequency to
PRIMARY ‐ 7 (Max Frequency).
