Temperature sensing using a temperature sensor
Table 6- 33 Parameters to sense the temperature using a temperature sensor
Parameters
Description
P0003 = 2
User access level
2: Extended
P0335 = 0
Specify the motor cooling
0: Self-ventilated
*
- with fan on the motor shaft (IC410
*
or IC411
*
) - (factory setting)
1: Forced ventilation
*
- with a separately driven fan (IC416
*
)
2: Self-ventilated
*
and inner cooling* (open-circuit air cooled)
3: Forced ventilated* and inner cooling* (open-circuit air cooled)
P0601 = 0
Specify the motor temperature sensor
0: No sensor (factory setting; → P0610)
1: PTC thermistor (→ P0604)
2: KTY84 (→ P0604)
4: ThermoClick sensor
6: PT1000
8: PTC thermistor (no short circuit protection mode)
P0604 = …
Motor overtemperature alarm threshold
(0°C … 220°C, factory setting 130°C)
Enter the alarm threshold for motor overtemperature protection. The shutdown tem-
perature threshold (alarm threshold + 10 %) is the value at which either the inverter is
shut down or I
max
is reduced (P0610).
P0610 = 2
This parameter is only visible, if P0003 = 3!
Response for motor overtemperature I
2
t
Defines the behavior as soon as the motor temperature reaches the alarm threshold.
0: No response, alarm only
1: Alarm and reduction of I
max
(reduces the output frequency)
2: Fault and shutdown (F0011) (factory setting)
P0640
Motor overload factor (entered in % referred to P0305: rated motor current)
