3.6 Main Menu - Digital In/Out - Group 5

3.6.1 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.
5-03 Digital Input 29 Mode
Option:
[0] PNP
*
[1] NPN
3.6.2 5-1* Digital Inputs
Parameters for configuring the input functions for the
input terminals.
The digital inputs are used for selecting various functions
in the frequency converter. All digital inputs can be set to
the following functions:
Digital input Description
function
[0] No operation No reaction to signals transmitted to
terminal.
[1] Reset Resets frequency converter after a TRIP/
ALARM. Trip locked alarms can be reset.
Leaves motor in free mode. Logic '0' ⇒
[2] Coast inverse
coasting stop.
[3] Coast and reset Reset and coasting stop inverted input
inverse (NC). Leaves motor in free mode and
resets the frequency converter. Logic '0' ⇒
coasting stop and reset.
[4] Quick Stop Inverted input (NC). Generates a stop in
inverse accordance with the quick-stop ramp time
set in 3-81 Quick Stop Ramp Time. After
ramping down, shaft is in free mode.
TR150 Programming Guide
Function:
BAS-SVP16A-EN - Rev. 2013-09-05
Digital input Description
function
[5] DC-brake inverse Inverted input for DC braking (NC). Stops
motor by energising it with DC current for
a certain time period, see 2-01 DC Brake
Current. Function is only active when
value in 2-02 DC Braking Time is different
from 0. This selection is not possible
when 1-10 Motor Construction is set to [1]
PM non salient SPM.
[6] Stop inverse Stop inverted function. Generates stop
function when selected terminal goes
from logical level "1" to "0" (not latched).
Stop is performed according to selected
ramp time.
[7] External Interlock Same function as Coasting stop, inverse,
but External Interlock generates the alarm
message 'external fault' on the display
when the terminal which is programmed
for Coast Inverse is logic '0'. The alarm
message is also active via digital outputs
and relay outputs, if programmed for
External Interlock. The alarm can be reset
using a digital input, fieldbus, or the
[Reset] key if the cause for the External
Interlock has been removed.
*[8] Start Select start for a start/stop command.
Logic '1' = start, logic '0' = stop. (Default
Digital input 18)
[9] Latched start Motor starts, if a pulse is applied for min.
2 ms. Motor stops when Stop inverse is
activated.
[10] Reversing Change direction of motor shaft rotation.
Reversing signal only changes direction of
rotation; it does not activate start
function. Select [2] Both directions in
4-10 Motor Speed Direction. 0 = normal, 1
= reversing.
[11] Start reversing Use for start/stop and for reversing at the
same time. Signals on [8] start are not
allowed at the same time. 0 = stop, 1 =
start reversing.
[14] Jog Used for activating jog speed. See
3-11 Jog Speed [Hz]. (Default Digital input
29)
[16] Preset ref bit 0 Enables a selection between one of the 8
preset references according to Table 3.4.
[17] Preset ref bit 1 Enables a selection between one of the 8
preset references according to Table 3.4.
[18] Preset ref bit 2 Enables a selection between one of the 8
preset references according to Table 3.4.
