7.15.4 Current underload protection
The motor current has fallen below the settable value.
The voltage to the softstarter is too low. The protection
measures voltage and checks if the voltage is too low, if it
is too low, the softstarter will trip.
This protection is only operational in the Top of ramp
state.
Check that the motor current parameter (Ie) is set
correctly.
Current underload protection is configured with the
following parameters:
Parameter
14.01 Curr underload level
14.02 Curr underload trip time
14.03 Curr underload delay time
14.04 Curr underload out
14.05 Curr underload op

7.15.5 Power factor underload protection
The power factor has fallen below the normal level.
The Power factor underload protection can be used to
supervise the load of the motor. If the load decreases the
power factor will decrease as well.
This protection is only operational in the Top of ramp
state.
Power factor underload protection is configured with
the following parameters:
Parameter
14.06 Pwr factor underload level
14.07 Pwr factor underload trip time
14.08 Pwr factor underload delay time
14.09 Pwr factor underload out
14.10 Pwr factor underload op
