Introduction
RCD
Residual Current Device.
Set-up
Parameter settings in 2 set-ups can be saved. Change
between the 2 parameter set-ups and edit one set-up,
while another set-up is active.
Slip compensation
The frequency converter compensates for the motor slip
by giving the frequency a supplement that follows the
measured motor load keeping the motor speed almost
constant.
Smart Logic Control (SLC)
The SLC is a sequence of user defined actions executed
when the associated user defined events are evaluated as
true by the SLC.
Thermistor
A temperature-dependent resistor placed where the
temperature is to be monitored (frequency converter or
motor).
Trip
A state entered in fault situations, e.g. if the frequency
converter is subject to an over-temperature or when the
frequency converter is protecting the motor, process or

mechanism. Restart is prevented until the cause of the
fault has disappeared and the trip state is cancelled by
activating reset or, in some cases, by being programmed
to reset automatically. Trip may not be used for personal
safety.
Trip locked
A state entered in fault situations when the frequency
converter is protecting itself and requiring physical
intervention, for example, if the frequency converter is
subject to a short circuit on the output. A locked trip can
only be cancelled by cutting off mains, removing the cause
of the fault, and reconnecting the frequency converter.
Restart is prevented until the trip state is cancelled by
activating reset or, in some cases, by being programmed
to reset automatically. Trip locked may not be used for
personal safety.
