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 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 No reaction to signals transmitted to the
operation terminal.
[1] Reset Resets frequency converter after a TRIP/
ALARM. Not all alarms can be reset.
[2] Coast (Default Digital input 27): Coasting stop,
inverse inverted input (NC). The frequency converter

leaves the motor in free mode. Logic '0'
⇒coasting stop.
Reset and coasting stop inverted input (NC).
Leaves motor in free mode and resets
frequency converter. Logic '0' ⇒ coasting stop
and reset.
Inverted input (NC). Generates a stop in
accordance with quick-stop ramp time set in
3-81 Quick Stop Ramp Time. When motor stops,
the shaft is in free mode. Logic '0' ⇒ Quick-
stop.
Inverted input for DC braking (NC). Stops
motor by energising it with a DC current for a
certain time period. See 2-01 DC Brake Current
to 2-04 DC Brake Cut In Speed [Hz]. The
function is only active when the value in
2-02 DC Braking Time is different from 0.
Logic '0' => DC braking.
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
(3-42 Ramp 1 Ramp Down Time,
parameter 3-52 Ramp 2 Ramp Down Time).
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
Torque limit & stop [27] and connect this
digital output to a digital input that is
configured as coast.
(Default Digital input 18): Select start for a
start/stop command. Logic '1' = start, logic '0'
= stop.
The motor starts, if a pulse is applied for min.
2 ms. The motor stops when [6] Stop inverse is
activated or a reset command (via DI) is given.
(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
4-10 Motor Speed Direction. The function is not
active in process closed loop.
Used for start/stop and for reversing on the
same wire. Signals on start are not allowed at
the same time.
Disengages the counterclockwise movement
and allows for the clockwise direction.
Disengages the clockwise movement and
allows for the counterclockwise direction.
(Default Digital input 29): Use to activate jog
speed. See 3-11 Jog Speed [Hz].
