Functions dedicated to only 1 digital input are stated in the associated parameter.
All digital inputs can be programmed to these functions:
Table 8: 5-10 Digital Inputs - 1
Option
Function
[0]
No operation
No reaction to signals transmitted to the terminal.
[1]
Reset
Resets the drive after a trip/alarm. Not all alarms can be reset.
[2]
Coast inverse
(Default digital input 27): Coast stop, inverted input (NC). The drive leaves the motor in free mode. Logic
0
⇒
coast stop.
[3]
Coast and reset
inverse
Reset and coast stop inverted input (NC). Leaves the motor in free mode and resets the drive. Logic
0
⇒
coast stop and reset.
[4]
Quick stop in-
verse
Inverted input (NC). Generates a stop in accordance with 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 in-
verse
Inverted input for DC brake (NC). Stops motor by energizing it with a DC current for a certain time period.
See
parameter 2-01 DC Brake Current
to
parameter 2-03 DC Brake Cut In Speed [RPM]
. The function is only
active when the value in
parameter 2-02 DC Braking Time
is different from 0. Logic 0
⇒
DC brake.
[6]
Stop inverse
Stop inverted function. Generates a stop function when the selected terminal goes from logical level 1 to
logical level 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
,
•
Parameter 3-62 Ramp 3 Ramp down Time
, and
•
Parameter 3-72 Ramp 4 Ramp Down Time
.
NOTICE
When the drive is at the torque limit and has received a stop command, it may not stop by itself.
To ensure that the drive stops, configure a digital output to
[27] Torque limit and stop
. 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.
