3-Phase Control Only, PowerThrough
Selects whether the soft starter will allow PowerThrough operation. For critical applications this allows the soft starter to control the
motor with two-phase control, if the soft starter is damaged on one phase. PowerThrough only operates after the soft starter has
tripped on "Lx-Tx Shorted" and has been reset.
PowerThrough uses a two-phase soft start technology and additional care is required when sizing circuit breakers and
protection. Contact your local supplier for assistance.
PowerThrough remains active until '3-Phase Control Only' is reselected.
PowerThrough operation does not support Adaptive Control soft starting or soft stopping. In PowerThrough, the Digistart
IS will automatically select constant current soft starting and timed voltage ramp soft stopping. If PowerThrough is
enabled, Pr 2C and 2B must be set appropriately.
PowerThrough can only operate with internally bypassed soft starters.
PowerThrough only operates with in-line connected motors.
Sets the torque level for jog operation. See Jog Operation for details.
8.8.17 Group 16 - Protection action
These parameters define how the soft starter will respond to different protection events. The soft starter can trip, issue a warning, or
ignore different protection events as required. All protection events are written to the event log. The default action for all protections
is to trip the soft starter.
Protections 16P Ground Fault and 16R to 16W RTD/PT100 are only available if the RTD/PT100 and ground fault protection card
has been fitted.
Defeating the protection may compromise the starter and motor, and should only be done in the case of emergency.
Trip Starter, Warn & Log, Log Only
Selects the soft starter's response to each protection.
