LL[N] - Low Feedback Limit

Purpose:

 Speed limits

The parameters LL[2] and HL[2] define the limits of the allowed motor speed. If the

motor speed exceeds HL[2] or is lower than LL[2], the drive is automatically disabled

and the “Speed High Limit” fault (MF=0x20,000) is activated Speed limits are

restricted by the TS value according to the following:

For analog encoder, resolver, tachometer, potentiometer and digital halls:

SpeedLimit = minimum between 80,000,000 and 8e9/TS.

For quadrature encoder:

SpeedLimit = minimum between 20,000,000 and 8e9/TS.

 Position limits

LL[3] and HL[3] define the allowed motor position range for UM=3, 4 and 5. If the

motor position is smaller than LL[3] or larger than HL[3], the motor is automatically

disabled and the “Position High Limit” fault (MF=0x400000) is activated. In order to

re-enable the motor, modify the current position (PX) within the ranges of HL[3] and

LL[3].
