Parameter Function
Dependency: Up to 200% of rated motor current (P0305) or limit of inverter.
Note: The Hammer Start boost is calculated in the same way as Continuous Boost (P1310). As the stator re-
sistance is used, the calculated voltage is only accurate at 0Hz. Thereafter, it will vary in the same way as
Continuous Boost.
Setting in P0640 (motor overload factor [%]) limits the boost.
P3358[0...2] Number of hammer
cycles
The number of times the hammer start boost level (P3357) is applied.
Index: See P3350
P3359[0...2] Hammer on time [ms]
Time for which the additional boost is applied for each repetition.
Index: See P3350
Dependency: The time must be at least 3 x motor magnetization time (P0346).
P3360[0...2] Hammer off Time [ms]
Time for which the additional boost is removed for each repetition.
Index: See P3350
Note: During this time, the boost level drops to the level defined by P1310 (continuous boost).
P3361[0...2] Blockage clearing fre-
quency [Hz]
Defines the frequency at which the inverter runs in the opposite direction to the setpoint during the blockage
clearing reverse sequence.
Index: See P3350
P3362[0...2] Blockage clearing re-
verse time [s]
Sets the time for which the inverter runs in the opposite direction to the setpoint during the reverse se-
quence.
Index: See P3350
P3363[0...2] Enable rapid ramp
Selects whether the inverter ramps to, or starts directly from, the blockage clearing frequency (P3361).
0
1
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
The number of times the blockage clearing reversing cycle is repeated.
Index: See P3350
