Note
The protection function may be overridden under the following conditions:
- If the inverter is running and the protection signal becomes active, the signal is ignored.
- If the inverter is turning a motor due to active protection signal and a RUN command is received, RUN command
overrides the frost protection signal.
- Issuing an OFF command while protection is active will stop the motor.
p29623[0...n] Frost protection speed / Fro spd
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: p2000 Dynamic index: DDS, p0180
Unit group: 3_1 Unit selection: p0505 Function diagram: -
Min:
-210000.000 [rpm]
Max:
210000.000 [rpm]
Factory setting:
0.000 [rpm]
Description: Specifies the speed applied to the motor when frost protection is active.
And this parameter can't be changed when the frost or condensation function is active.
Dependency: See also p29622.
p29624[0...n] Condensation protection current / Cond current
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0.000 [%]
Max:
100.000 [%]
Factory setting:
30.000 [%]
Description: Specifies the DC current (as a percentage of rated current) applied to the motor when condensation protection is
active.
Dependency: See also p29622.
Note
The change to the current becomes effective the next time condensation protection is active.
p29625[0...n] Cavitation protection enable / Cavi en
Access level: 3 Calculated: - Data type: Integer16
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: -
Min:
0
Max:
2
Factory setting:
0
Description: Enables the cavitation protection function. A fault/alarm is generated when cavitation conditions are deemed to be
present.
Value: 0: The cavitation protection function is deactivated
1: The cavitation protection function triggers fault F52960
2: The cavitation protection function triggers warning A52961
p29626[0...n] Cavitation protection threshold / Cavi thresh
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: 9_1 Unit selection: p0595 Function diagram: -
Min:
0.00 [%]
Max:
200.00 [%]
Factory setting:
40.00 [%]
Description: Defines the feedback threshold (as a percentage) for triggering a fault/alarm.
