External Fault
External Faults (1 and 2) can be supervised by defining one digital input as a source
for an external fault indication signal.

EXTERNAL FAULT 2
Stall Protection
The drive protects the motor in a stall situation. It is possible to adjust the supervision
limits (frequency, time) and choose how the drive reacts to the motor stall condition
(alarm indication / fault indication & drive stop / no reaction).
Settings
Motor Thermal Protection
The motor can be protected against overheating by activating the Motor Thermal
Protection function.
The drive calculates the temperature of the motor on the basis of the following
assumptions:
1) The motor is in the ambient temperature of 30
°
C when power is applied to the
drive.
2) Motor temperature is calculated using either the user-adjustable or automatically
calculated motor thermal time constant and motor load curve (see the figures
below).
The load curve should be adjusted in case the ambient temperature exceeds
30°C.
Settings
Note:
It is also possible to use the motor temperature measurement function. See
