7.12.1 Digital inputs (DI)
The softstarter is equipped with five digital inputs for basic
control of the unit.
The five 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 can not be configured.
In0, In1 and In2 are programmable inputs. Functions can
be related to the physical signal through a drop down
menu on the HMI.
The programmable options are:
• None - No function on the digital input.
• Reset - Fault/protection reset.
• Enable - TBD
• Slow speed forward - While the digital input is high,

the motor will slowly move forward.
• Slow speed reverse - While the digital input is high,
the motor will slowly move in the reverse direction.
• Motor heating - While the digital input is high, the
motor heating is active.
• Stand still brake - While the digital input is high, the
stand still brake is active.
• Start reverse - TBD
• User defined protection - When activated (the
protection can be programmed to be active low or
high) the user defined protection will be activated.
• Fieldbus disable control - When the digital input
is set high, the motor cannot be controlled from the
fieldbus. Instead the start/stop digital input must be
used, or the HMI.
