Converter with CU230P-2 Control Units
Operating Instructions, 04/2015, FW V4.7 SP3, A5E34257946B AB
The converter switches off with fault in the following cases:
- motor temperature > p0605
- motor temperature > p0604 and p0610 ≠ 0
The converter interprets a resistance > 2120 Ω as a wire-break and outputs the alarm
A07015. After 100 milliseconds, the converter changes to the fault state with F07016.
The converter interprets a resistance < 50 Ω as a short-circuit and outputs the alarm
A07015. After 100 milliseconds, the converter changes to the fault state with F07016.
Description
Specify the motor cooling
0: Natural cooling - with fan on the motor shaft (factory setting)
1: Forced ventilation - with a separately driven fan
2: Liquid cooling
128: No fan
Motor-temperature sensor type
0: No sensor (factory setting)
1: PTC (→ p0604)
2: KTY84 (→ p0604, p0605)
4: Temperature switch
Motor temperature alarm threshold (factory setting 130° C)
Motor temperature fault threshold (factory setting 145° C)
Setting for KTY84 sensor. The parameter has no significance for a PTC sensor.
Motor overtemperature response (factory setting: 12)
Determines the behavior as soon as the motor temperature reaches the warning
threshold p0604.
0: Alarm (A07910), no fault.
1: Alarm (A07910); the converter reduces the current limit and starts the timer.
Shutdown with fault (F07011).
2: Alarm (A07910); the converter starts the timer. Shutdown with fault (F07011).
12: As for 2, but the converter considers the last shutdown temperature to calculate
the motor temperature.
