BI: Frost protection enable / Fro en

Access level: 3
Can be changed: T, U
Unit group: -
Min:
-
Description: Sets the signal source to enable frost protection. If the binary input is equal to 1, then protection will be initiated. If the
converter is stopped and the protection signal becomes active, protection measure is applied as follows:
- If p29623 != 0, frost protection is activated by applying the specified speed to the motor;
- If p29623 = 0, and p29624 != 0, condensation protection is activated by applying the specified current to the motor.
Note
The protection function may be overridden under the following conditions:
- If the converter is running and the protection signal becomes active, the signal is ignored.
- If the converter 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.

Frost protection speed / Fro spd

Access level: 3
Can be changed: T, U
Unit group: 3_1
Min:
-210000.000 [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
Can be changed: T, U
Unit group: -
Min:
0.000 [%]
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
Can be changed: T, U
Unit group: -
Min:
