Chapter 6 - Parameter Description [I/O]
6-56
I/O-84: Cooling Fan Control Selection
This parameter determines the operating condition of
the drives cooling fans.
I/O-84
Setting Range
Description
PowerOn Fan Fan is ON when power is ON.
Run Fan Fan is ON when the drive runs
(outputs frequency).
Temper Fan Fan is ON when the drive
temp exceeds the preset value
in I/O-85.
Note: I/O-84, 85 are only programmable for drives
50HP and higher.
I/O-85: Fan Temperature
When I/O-84 is set to Temper Fan, this parameter sets
the temperature at which the fans turn on.
Range 0 – 70 degrees Celsius
Note: I/O-84, 85 are only programmable for drives
50HP and higher.
I/O-86: User Unit selection (PI Mode only)
I/O-87: Units Maximum Value
When PID operation is selected in APP-02, APP-80, or
APP-62, the drive displays units in PSI, rather than
speed (Hz.). The user can chose units to display listed
in the table below.

Description
Percent
Flow rate, pressure and
temperature are displayed in
[%].
Bar Pressure is displayed in [Bar].
mBar
Pressure is displayed in
[mBar].
kPa Pressure is displayed in [kPa].
Pa Pressure is displayed in [Pa].
Psi Pressure is displayed in [Psi].
Scaling: I/O-87
, Unit Maximum Value is used to set
the maximum value of the units selected in I/O-86. If
PSI (I/O-86) is selected and sensor maximum pressure
is 300 PSI, enter 300 PSI. When “I” is selected as the
feedback (APP-06 default), scaling of the “I” is done
with parameters I/O-87, Max. Pressure along with
parameter APP-31 “meter I max”. These two
parameters set the maximum pressure at the maximum
feedback signal (default is 20mA). See table below.
