Setting the UL508C/UL61800-5-1-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 or 4 will cause the inverter to trip
(F11) if the motor temperature is 10% above the warning threshold P0604.
Note
In order to comply with UL508C/UL61800-5-1, parameter P0610 must not be changed from
its factory setting of 6.

Setting the free function blocks (FFBs)

Functionality
Additional signal interconnections in the inverter can be established by means of the free
function blocks (FFBs). Every digital and analog signal available via BICO technology can be
routed to the appropriate inputs of the free function blocks. The outputs of the free function
blocks are also interconnected to other functions using BICO technology.

Setting
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)
