t temperature
reaction
0 - 6 6 T - DDS U16 3
Defines reaction when motor temperature reaches warning threshold.
0 Warning only. Does not recall the motor temperature (stored at power down) on
power up
1 Warning with Imax control (motor current reduced) and trip (F11). Does not
recall the motor temperature (stored at power down) on power up
2 Warning and trip (F11). Does not recall the motor temperature (stored at power
down) on power up
4 Warning only. Recalls the motor temperature (stored at power down) on power
up
5 Warning with Imax control (motor current reduced) and trip (F11). Recalls the
motor temperature (stored at power down) on power up
6 Warning and trip (F11). Recalls the motor temperature (stored at power down)
on power up
Dependency: Trip level = P0604 (motor temperature threshold) * 110 %
Note:
•
P0610 = 0 (No reaction, warning only)
When temperature reaches warning level defined in P0604, the inverter displays warning A511, no
reaction is done.
• P0610 = 1 (Warning, Imax reduction and Trip)
When temperature reaches warning level defined in P0604, the inverter displays warning A511, reduce
frequency and trips F11, when temperature exceeds the trip level.
• P0610 = 2 (Warning and trip F11)
When temperature reaches warning level defined in P0604, the inverter displays warning A511 and trips
F11, when temperature exceeds the trip level.
The purpose of motor I
2
t is to calculate the motor temperature and disable the inverter if the motor is in
danger of overheating.
I
2
t operation:
The measured motor current is displayed in r0027. The motor temperature in °C is displayed in r0035.
This temperature is derived from a calculated value using motor thermal model.
The reaction to the warning can be changed from this default using P0610.
r0035 is particularly useful to monitor if the calculated motor temperature is rising excessively.
P0622[0...2] Magnetizing time for
temp id after start up

0.000 -
20000
0.000 U, T - DDS Float 3
Specifies the magnetization time for stator resistance identification.
r0623[0...2] CO: Display for the
identified stator
resistance [Ohm]
- - - - DDS Float 4
Display of the actual identified stator resistance after temperature identification.
P0625[0...2] Ambient motor
temperature [°C]
-40.0 -
80.0
20.0 C(1), U, T - DDS Float 3
Ambient temperature of motor at time of motor data identification. It is only allowed to change the value
when the motor is cold. A motor identification has to be made after changing the value.
Dependency: This parameter is influenced by automatic calculations defined by P0340.

200.0
50.0 U, T - DDS Float 4
Overtemperature of stator iron.
