The parameter number
DRV-25 will flash over
Output value while VFD is stopped as an indication
of the current parameter. The PID Values Display
shows [R] R
eference (Set-point) and [F] Feedback
(Transducer reading) as a percentage of the SET-25
transducer range. The [T] T
arget Hz is the speed
reference that PID provides to VFD to follow and
[O] Output Hz is the actual VFD output frequency.
This parameter display is very useful for PID and
transducer operation adjustment or trouble-
shooting.

The readings shown on
this display are raw AD
converter values from 0 to approximately 4095
depending on VFD calibration values.
V1 value divided approximately by 337
represents the analog 0-10VDC signal on V1 input.
V1S value will be shown only when bi-polar
analog input is selected in SET-10. The following
readings approximately represent analog signal
values: 0 is -12VDC, 2040 is 0VDC and 4095 is
+12VDC.
V2 value will be shown when expansion analog
card is installed.
I value divided approximately by 204 represents
the analog 4-20mA signal on I input. This
parameter display is very useful for PID and
transducer operation adjustment or trouble-
shooting.

The External PID
Values Display shows
[R] Reference (Set-point), [F] Feedback
(Transducer reading) as a percentage of the SET-25
transducer range. The [O] O
utput value is a
percentage of the VFD maximum output frequency.
This parameter display is very useful for EXT-PID
operation adjustment or trouble-shooting.

The Drive Mode2
parameter will be
available when SET-90 is set to 2
nd
Source and
determines the source of the Start/Stop command to
VFD when LOC/REM key or LOC/REM digital
input is used to switch VFD to 2
nd
Source. The
selection choices are: Keypad, Remote-1 and
Remote-2. Refer to parameter SET-09 for detailed
control mode descriptions.
)5+1! "
The Frequency
Mode2 parameter will
be available when SET-90 is set to 2
nd
Source and
determines the source of the speed reference
command to VFD when LOC/REM key or
LOC/REM digital input is used to switch VFD to
2
nd
Source. The selection choices are: Keypad-1,
Keypad-Up/Down, V1, V1S, I, V1+I, and Pulse.
Refer to parameter SET-10 for detailed
descriptions.
