V/I
— The V/I terminal has the dual function of being able to receive an input voltage or current. The
function as a voltage input is to receive a 0 – 10 VDC input signal. The function as a current input is to
receive a 0 – 20 mA input signal. Using either input type, the function is to control the 0.0 – Maximum
Frequency output or the 0.0 to 250% torque output of the ASD. This is an isolated input terminal. This
terminal may be programmed to control the speed or torque of the motor and cannot process both input
types simultaneously.
must be set to V or I to receive a voltage or current, respectively (see
). Terminal scaling is accomplished via
. The gain and bias of this
terminal may be adjusted for application-specific suitability (see
and
+SU
—
Control Power Supply Backup
input terminal. This terminal accepts the user-supplied
24 VDC backup power to the control circuits (only). Backup power is used in the event of an open
MCCB or during a momentary loss of the 3-phase input power and cannot be supplied by the 3-phase
input power. Parameter settings, real-time clock information, and trip history information are retained
with the use of the
+SU
backup power.
The P9 ASD is equipped with an EOI-mounted battery for this function. The battery backup has the
added feature of allowing for the transfer of the EOI to another ASD while retaining the control
programming. See the section titled
for additional information on the battery
backup features.
P24
— +24 VDC at 200 mA power supply for customer use.
PP
— The function of output
PP
is to provide a 10 VDC/10 mADC (max.) output that may be divided
using a potentiometer. The tapped voltage is applied to the
RR
input to provide manual control of the
RR
programmed function.
O1A/B
(OUT1A/B)
— The default function assigned to this terminal is
. The
function as
External Device 1
is to activate/deactivate an auxiliary motor once the
Virtual Linear
Pump
level has remained above the
Maximum
threshold setting
or below the
Minimum
threshold
setting
. The
OUT1
terminal is rated at 2 A/120 VAC and 2 A/30 VDC. This
terminal may be set to any of the functions listed in
).
O2A/B
(OUT2A/B)
— The default function assigned to this terminal is
. The
function as
External Device 2
, in conjunction with External Device 1, is to activate/deactivate an
auxiliary motor once the control level of the Virtual Linear Pump settings has remained above the
Maximum
threshold or below the
Minimum
threshold settings for the time setting of
. The
OUT2
terminal is rated at 2 A/120 VAC and 2 A/30 VDC. This terminal may be set to any of the functions
listed in
FP
— The default function of this output terminal is to output a series of pulses at a rate that is a
function of the ASD output frequency (50 mA max. at 1.0 kHz to 43.3 kHz). As the output frequency of
the ASD goes up, so does the
FP
output pulse rate. This terminal may be programmed to provide an
output pulse rate that is proportional to the magnitude of the user-selected item from
For additional information on this terminal, see
AM
—
This output terminal produces an output voltage that is proportional to the output frequency of
the ASD or of the magnitude of the function assigned to this terminal. The available assignments for
this output terminal are listed in
. For additional information on this terminal, see
.
FM
— This output terminal produces an output current or voltage that is proportional to the output
frequency of the ASD or of the magnitude of the function assigned to this terminal. The available
assignments for this output terminal are listed in
. For additional information on this
terminal, see
. The Voltage/Current output selection is performed at

FLA
— One of two normally open contacts that, under user-defined conditions, connect to
FLC
