P3852[0...2] BI: Enable frost protec-
tion
Defines command source of protection enable command. If binary input is equal to one, then protection will
be initiated. If inverter is stopped and protection signal becomes active, protection measure is applied as
follows:
If P3853 ≠ 0, frost protection is applied by applying the given frequency to the motor
•
If P3853 = 0, and P3854 ≠ 0, condensation protection is applied by applying the given current to the
•
motor
Note: The protection function may be overridden under the following circumstances:
If inverter is running and protection signal becomes active, signal is ignored
•
If inverter is turning motor due to active protection signal and a RUN command is received, RUN com-
•
mand overrides frost signal
Issuing an OFF command while protection is active will stop the motor
•
P3853[0...2] Frost protection fre-
quency [Hz]
The frequency applied to the motor when frost protection is active.
Dependency: See also P3852.
P3854[0...2] Condensation protec-
tion current [%]
The DC current (as a percentage of nominal current) which is applied to the motor when condensation
protection is active.
Dependency: See also P3852.
P3900 End of quick commis-
sioning
Performs calculations necessary for optimized motor operation. After completion of calculation, P3900 and
P0010 (parameter groups for commissioning) are automatically reset to their original value 0.
