I/O Terminal Descriptions
Note:
The programmable terminal assignments of the discrete input terminals may be
accessed and changed from their default settings as mapped on
pg. 42
(see Input
Terminals).
ST — The default setting for this terminal is ST. The function of this input as ST is a Standby mode
controller (system is in Standby when on). As the default setting, this terminal must be connected to
CC for normal operation. If not connected to CC, Off is displayed on the LCD screen. This input
terminal may be programmed to any 1 of the 69 functions that are listed in
Table 6 on page 138
. See
ST
Terminal on pg. 128
for more information on this terminal.
RES — The default setting for this terminal is RES. The function of this input as RES is a system
Reset. A momentary connection to CC resets the ASD and any fault indications from the display. This
input terminal may be programmed to any 1 of the 69 possible functions that are listed in
Table 6 on
page 138
. Reset is effective when faulted only. See
RES Terminal on pg. 106
for more information on
this terminal.
F — The default setting for this terminal is Forward Run. Forward Run runs the motor in the
Forward direction when it is on. This input terminal may be programmed to any 1 of the 69 functions
that are listed in
Table 6 on page 138
. See
F Terminal on pg. 75
for more information on this terminal.
R — The default setting for this terminal is Reverse Run. Reverse Run runs the motor in the Reverse
direction when it is on. This input terminal may be programmed to any 1 of the 69 functions that are
listed in
Table 6 on page 138
. See
R Terminal on pg. 111
for more information on this terminal.
S1 — The default setting for this terminal is S1. The function of this input as S1 is to run the motor at
Preset Speed #1 (see
Preset Speed #1 on pg. 100
) when it is on. This input terminal may be
programmed to any 1 of the 69 functions that are listed in
Table 6 on page 138
. See
S1 Terminal on pg.
119
for more information on this terminal.
S2 — The default setting for this terminal is S2. The function of this input as S2 is to run the motor at
Preset Speed #2 (see
Preset Speed #2 on pg. 100
) when it is on. This input terminal may be
programmed to any 1 of the 69 functions that are listed in
Table 6 on page 138
. See
S2 Terminal on pg.
120
for more information on this terminal.
S3 — The default setting for this terminal is S3. The function of this input as S3 is to run the motor at
Preset Speed #3 (see
Preset Speed #3 on pg. 101
) when it is on. This input terminal may be
programmed to any 1 of the 69 functions that are listed in
Table 6 on page 138
. See
S3 Terminal on pg.
120
for more information on this terminal.
S4 — The default setting for this terminal is Emergency Off (normally closed). The function of this
input as Emergency Off is to remove power from the output of the ASD and may apply a supplemental
braking system using the method selected at the Emg Off Mode selection parameter. This input
terminal may be programmed to any 1 of the 69 functions that are listed in
Table 6 on page 138
. See
S4
Terminal on pg. 121
for more information on this terminal.
RR — The default function assigned to this terminal is to carry out the Frequency Mode #1 setting.
The RR terminal accepts a 0 – 10 VDC input signal and controls the function assigned to this terminal.
This input terminal may be programmed to control the speed or torque of the motor. It may also be used
to regulate (limit) the speed or torque of the motor. The gain and bias of this terminal may be adjusted
for application-specific suitability.
See
RR Speed Frequency Setpoint #1 on pg. 107
for more
information on this terminal.
RX — The RX terminal accepts a ±10 VDC input signal and controls the function assigned to this
terminal. This input terminal may be programmed to control the speed, torque, or direction of the motor.
It may also be used to regulate (limit) the speed or torque of the motor. The gain and bias of this
terminal may be adjusted for application-specific suitability.
See
RX Speed Frequency Setpoint #1 on
pg. 116
for more information on this terminal.
