NOTE
To achieve the highest accuracy with the slip compensation, an Automatic Motor Adaptation (AMA) should be per-
formed. To be enabled in par.1-29
NOTE
Trip will not be active when using a normal stop or coast command.

Automatic Motor Adaptation
Function:
If the trip speed is set to 0, the function is not active.
If the speed after the start (or during a stop) falls below the value in the
parameter at any time, the drive will trip with an alarm [A49] Speed Limit.
Function at stop.
Motor Speed Unit
Function:
If the trip speed is set to 0, the function is not active.
If the speed after the start (or during a stop) falls below the value in the
parameter at any time, the drive will trip with an alarm [A49] Speed Limit.
Function at stop.
Motor Speed Unit
Function:
The adjustable frequency drive determines the motor temperature for
motor protection in two different ways:
• Via a thermistor sensor connected to one of the analog or digital
inputs (par.1-93
• Via calculation (ETR = Electronic Thermal Relay) of the thermal
load, based on the actual load and time. The calculated ther-
mal load is compared with the rated motor current I M,N and
the rated motor frequency f M,N . The calculations estimate the
need for a lower load at lower speed due to less cooling from
the fan incorporated in the motor.
If the motor is continuously overloaded and no warning or trip of ad-
justable frequency drive is wanted.
Activates a warning when the connected thermistor in the motor reacts
in the event of motor overtemperature.
Stops (trips) the adjustable frequency drive when the connected ther-
mistor in the motor reacts in the event of motor overtemperature.
