4.6 Parameters: 5-** Digital In/Out
4.6.1 5-0* Digital I/O Mode
Parameters for configuring the input and output using
NPN and PNP.
NOTICE
These parameters cannot be adjusted while the motor is
running.
5-00 Digital Input Mode
Option:
Function:
Set NPN or PNP mode for digital inputs 18, 19, and
27. Digital input mode.
[0]
*
PNP Action on positive directional pulses (0). PNP systems
are pulled down to ground (GND).
[1]
NPN Action on negative directional pulses (1). NPN
systems are pulled up to +24 V, internally in the
frequency converter.
5-01 Terminal 27 Mode
Option:
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
[0]
*
Input
Defines terminal 27 as a digital input.
[1]
Output Defines terminal 27 as a digital output.
5-02 Terminal 29 Mode
Option:
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
[0]
*
Input
Defines terminal 29 as a digital input.
[1]
Output Defines terminal 29 as a digital output.
4.6.2 5-1* Digital Inputs
The digital inputs are used for selecting various functions
in the frequency converter.
5-10 to 5-16 Digital Inputs
[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
(Default Digital input 27): 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 the quick stop ramp time set
in
parameter 3-81 Quick Stop Ramp Time
. When
the motor stops, the shaft is in free mode.
Logic 0
⇒
Quick-stop.
[5]
DC-brake
inverse
Inverted input for DC braking (NC). Stops the
motor by energising it with a DC current for a
certain time period. See
parameter 2-01 DC
Brake Current
to
parameter 2-04 DC Brake Cut In
Speed [Hz]
. The function is only active when
the value in
parameter 2-02 DC Braking Time
is
different from 0. Logic 0=>DC braking.
[6]
Stop
inverse
NOTICE
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 and stop
and connect this
digital output to a digital input that is
configured as coast.
Stop inverted function. Generates a stop
function when the selected terminal goes from
logic 1 to logic 0. The stop is performed
according to the selected ramp time
(
parameter 3-42 Ramp 1 Ramp Down Time
,
parameter 3-52 Ramp 2 Ramp Down Time
).
[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 when a pulse is applied for
minimum 2 ms. The motor stops when
[6] Stop
inverse
is activated or a reset command (via DI)
is given.
[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
parameter 4-10 Motor Speed Direction
. 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
parameter 3-11 Jog Speed [Hz]
.
