H9 ASD Installation and Operation Manual

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.
SW301
must be set to V or I to receive a voltage or current, respectively (see
Figure 9 on pg. 24
). Terminal scaling and the selection of speed or torque control is accomplished via
parameters
F201
–
F206
. The gain and bias of this terminal may be adjusted for application-specific
suitability (see
F470
and
F471
).
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. Parameter settings, real-time clock
information, and trip history information are retained with the use of the
SU+
backup power. See the
section titled
Battery Backup on pg. 28
for more information on system 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
Output Low-Speed
. This
output may be programmed to provide an indication (open or closed) that any of the functions listed in
Table 8 on pg. 239
has occurred or is active. This function may be used to signal external equipment
(e.g., activate the brake) (see
F130
). The
OUT1
terminal is rated at 2 A/120 VAC and 2 A/30 VDC.
O2A/B
(OUT2A/B) — The default function assigned to this terminal is
ACC/DEC Complete
. This
output may be programmed to provide an indication (open or closed) that any of the functions listed in
Table 8 on pg. 239
has occurred or is active. This function may be used to signal external equipment
(e.g., activate the brake) (see
F131
). The
OUT2
terminal is rated at 2A/120 VAC and 2A/30 VDC.
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
Table 6 on pg. 237
.
For further information on this terminal see
F676 on pg. 193
.
AM
—
This output terminal produces an output current 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
Table 6 on pg. 237
. For further information on this terminal see
F670
on pg. 192
.
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
Table 6 on pg. 237
. For further information on this
terminal see
F005 on pg. 78
. The Voltage/Current output selection is performed at
F681
.
FLA
— One of two normally open contacts that, under user-defined conditions, connect to
FLC
.
FLB
— One of two normally closed contacts that, under user-defined conditions, connect to
FLC
.
FLC
—
FLC
is the common leg of a single-pole double-throw form C relay. The
FL
relay is the
Fault
Relay
by default, but may be programmed to any of the selections of
Table 8 on pg. 239
. For further
information on this terminal see
F132
and
Figure 8
.
Note:
The
FLA
,
FLB
,
and
FLC
contacts are rated at 2A/120 VAC and 2A/30 VDC.
