AF-650 GP standard terminals are 18, 19, 27, 29, 32 and 33. OPCGPIO General Purpose I/O Option Module terminals are
X30/2, X30/3 and X30/4.
Functions dedicated to only one digital input are stated in the associated parameter.
All digital inputs can be programmed to these functions:
[0] No
operation
No reaction to signals transmitted to the
terminal.
[1] Reset Resets frequency converter after a TRIP/
ALARM. Not all alarms can be reset.
[2] Coast
inverse
Coasting stop, inverted input (NC). The
frequency converter leaves the motor in free
mode. Logic ‘0’ => coasting stop.
[3] Coast and
reset inverse
Reset and coasting stop Inverted input (NC).
Leaves motor in free mode and resets
frequency converter. Logic ‘0’ => coasting
stop and reset.
[4] Quick stop
inverse
Inverted input (NC). Generates a stop in
accordance with quick-stop ramp time set in
C-23 Quick Stop Decel Time . When motor
stops, the shaft is in free mode. Logic ‘0’ =>
Quick-stop.
[5] DC-brake
inverse
Inverted input for DC braking (NC). Stops
motor by energizing it with a DC current for
a certain time period. See B-01 DC Brake
Current to B-03 DC Brake Cut In Speed [RPM] .
The function is only active when the value in
B-02 DC Braking Time is different from 0.
Logic ’0’ => DC braking.
[6] Stop inverse Stop Inverted function. Generates a stop
function when the selected terminal goes
from logical level ‘1’ to ‘0’. The stop is
performed according to the selected ramp
time ( F-08 Decel Time 1 , E-11 Decel Time 2 ,
E-13 Decel Time 3 , E-15 Decel Time 4 ).
NOTE
When the frequency converter is at the
torque limit and has received a stop
command, it may not stop by itself. To
ensure that the frequency converter
stops, configure a digital output to
[27]
Torque limit & stop and connect this
digital output to a digital input that is
configured as coast.
[8] Start (Default Digital input 18): Select start for a
start/stop command. Logic ‘1’ = start, logic ‘0’
= stop.
[9] Latched
start
The motor starts, if a pulse is applied for min.
2 ms. The motor stops when Stop inverse is
activated.
[10] Reversing (Default Digital input 19). Change the
direction of motor shaft rotation. Select Logic
‘1’ to reverse. The reversing signal only
changes the direction of rotation. It does not
activate the start function. Select both
directions in H-08 Reverse Lock . The function
is not active in process closed loop.
[11] Start
reversing
Used for start/stop and for reversing on the
same wire. Signals on start are not allowed at
the same time.
[12] Enable start
forward
Disengages the counterclockwise movement
and allows for the clockwise direction.
[13] Enable start
reverse
Disengages the clockwise movement and
allows for the counterclockwise direction.
[14] Jog (Default Digital input 29): Use to activate jog
speed. See C-20 Jog Speed [Hz] .
[15] Preset
reference on
Shifts between external reference and preset
reference. It is assumed that [1] External/preset
has been selected in F-54 Reference Function .
Logic '0' = external reference active; logic '1'
= one of the eight preset references is active.
[16] Preset ref bit
0
Preset ref. bit 0,1, and 2 enables a choice
between one of the eight preset references
according to the table below.
[17] Preset ref bit
1
Same as Preset ref bit 0 [16].
[18] Preset ref bit
2
Same as Preset ref bit 0 [16].
