7.14.2 Digital inputs (DI)
The Softstarter has 5 digital inputs for basic control of the
unit.
The 5 digital inputs are terminal 13, 14, 15, 16 and 17.
The inputs are named
• Start
• Stop
• In0
• In1
• In2
Start and Stop inputs are fixed to start and stop function
and cannot be changed.
In0, In1 and In2 are programmable inputs. Functions can
be related to the physical signal through a drop down
menu on the HMI.
Use the inputs with 24 V and current sinking type, 10mA.
The digital input is isolated and can withstand up to 100V
in potential difference between the Softstarter functional
ground and the ground of the interconnected system. You
can use the input with internal 24 V or external 24 V supply.
The digital input values for respective input voltage:
“0” = 0 – 5 V
“1” = 15 – 33 V
Maximum voltage input is 33 V and minimum is -0.5
V. Outside these voltage ranges the digital value is
undefined and can be either “0” or “1”.
Internal digital Inputs (Internal I/O) have these
parameters:
Parameter Description Setting range Default value
10.01 In0 function Function of programmable digital
input.
None, Reset, Enable, Slow speed forward, Slow
speed reverse, Motor heating, Stand-still brake,
Start reverse, User defined protection, Emergency
mode (active high), Emergency mode (active low),
