Note: If the encoder is enabled (P0400 > 0) and the motor holding brake is enabled (P1215 > 0) then in order to stop
encoder loss trips when the brake is applied, the allowed speed difference P0492 should be > f_min (P1080).
The Factory setting depends on motor power.
Description: Used for low speed encoder loss detection.
If the motor shaft speed is less than the value in P0492 then encoder loss is detected using a low speed encoder
loss detection algorithm.
This parameter selects the delay between loss of encoder at low speed and reaction to the encoder loss.
Dependency: This parameter is updated when motor start-up time P0345 is changed or when a speedloop optimisation is per-
formed (P1960 = 1).
Caution: P0494 = 0 (disabled):
When the delay in P0494 is set to 0, then low speed encoder loss detection is disabled and low speed encoder loss
cannot be detected (high speed encoder loss detection will still operate if P0492 > 0).
If low speed encoder loss detection is disabled and encoder should be lost at low speed, then operation of motor
may become unstable.
Note: If the encoder is enabled (P0400 > 0) and the motor holding brake is enabled (P1215 > 0), then in order to stop
encoder loss trips when the brake is applied, the delay speed loss reaction should be > brake holding times (i.e.
P0494 > P1216 and P494 > P1217).
The Factory setting depends on motor power.
Description: Selects technological application.
Sets control mode (P1300).
Values: 0: High overload
1: Pumps and fans
Dependency: See parameter P0205.
