Setting the UL508C-compliant motor overtemperature protection
Functionality
The function protects the motor from overtemperature. The function defines the reaction of
the inverter when motor temperature reaches warning threshold. The inverter can remember
the current motor temperature on power-down and reacts on the next power-up based on the
setting in P0610. Setting any value in P0610 other than 0 will cause the inverter to trip (F11)
if the motor temperature is 10% above the warning threshold P0604.

t temperature reaction
This parameter defines reaction when motor temperature
reaches warning threshold.
Settings 0 to 2 do not recall the motors temperature (stored at
power-down) on power-up:
= 0: Warning only
= 1: Warning with Imax control (motor current reduced) and trip
(F11)
= 2: Warning and trip (F11)
Settings 4 to 6 recall the motors temperature (stored at power-
down) on power-up:
= 4: Warning only
= 5: Warning with Imax control (motor current reduced) and trip
(F11)
= 6: Warning and trip (F11)
