Level
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.
Index: See P3350
r3365 Status word: super
torque
- - - - - U16 2
Shows the operational status of the Super Torque function, while active.
Bit Signal name 1 signal 0 signal
00 Super Torque Active Yes No
01 Super Torque Ramping Yes No
02 Super Torque Boost On Yes No
03 Super Torque Boost Off Yes No
04 Blockage Clearing Reverse On Yes No
05 Blockage Clearing Reverse Off Yes No
P3852[0...2] BI: Enable frost
protection
- 0 T - CDS U32 /
Bin
2
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
command overrides frost signal
• Issuing an OFF command while protection is active will stop the motor
P3853[0...2] Frost protection
frequency [Hz]
0.00 -
599.00
5.00 U, T - DDS Float 2
The frequency applied to the motor when frost protection is active.
Dependency: See also P3852.
P3854[0...2] Condensation protection
current [%]
0 - 250 100 U, T - DDS U16 2
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
commissioning
0 - 3 0 C(1) - - U16 1
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.
0 No quick commissioning
1 End quick commissioning with factory reset
2 End quick commissioning
