P3361[0...2]
Blockage clearing fre-
quency [Hz]
0.0 - 550.0 5.0 T - - Float 2
Defines the frequency at which the converter runs in the opposite direction to the setpoint during the block-
age clearing reverse sequence.
Index:
See P3350
P3362[0...2]
Blockage clearing re-
verse time [s]
0.0 - 20.0 5.0 T - - Float 2
Sets the time for which the converter runs in the opposite direction to the setpoint during the reverse se-
quence.
Index:
See P3350

2
Selects whether the converter ramps to, or starts directly from, the blockage clearing frequency (P3361).
0
Disable rapid ramp for blockage clearing
1
Enable rapid ramp for blockage clearing
Index:
See P3350
Note:
If P3363 = 1, the output jumps to the reverse frequency - this introduces a "kicking" effect which helps to
clear the blockage.
P3364[0...2]
Number of blockage
clearing cycles
1 - 10 1 T - - U16 2
The number of times the blockage clearing reversing cycle is repeated.

Defines command source of protection enable command. If binary input is equal to one, then protection will
be initiated. If converter 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 converter is running and protection signal becomes active, signal is ignored
• If converter is turning motor due to active protection signal and a RUN command is received, RUN
command overrides frost signal
• Issuing an OFF command while protection is active will stop the motor
