R compensation
When IR compensation is activated, the drive
gives an extra voltage boost to the motor at low
speeds. IR compensation is useful in
applications that require high breakaway torque.

Parameter 2603 IR COMP VOLT
Programmable protection functions

AI<Min
AI<Min function defines the drive operation if an analog input signal falls below the
set minimum limit.
Settings
Parameters 3001 AI<MIN FUNCTION , 3021 AI1 FAULT LIMIT and 3022 AI2 FAULT
LIMIT

Panel loss
The Panel loss function defines the operation of the drive if the control panel selected
as control location for the drive stops communicating.
Settings
Parameter 3002 PANEL COMM ERR

External fault
External faults (1 and 2) can be supervised by defining one digital input as a source
for an external fault indication signal.
Settings
Parameters 3003 EXTERNAL FAULT 1 and 3004 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).
