Note: The Super Torque boost is calculated in the same way as Continuous Boost (P1310). As the stator
resistance is used, the calculated voltage is only accurate at 0 Hz. Thereafter, it will vary in the same way
as Continuous Boost.
Setting in P0640 (motor overload factor [%]) limits the boost.
P3356[0...2] Super torque boost time
[s]
0.0 - 20.0 5.0 T - - Float 2
Sets the time for which the additional boost will be applied, when the output frequency is held at P3354
Hz.
Index: See P3350
P3357[0...2] Hammer start boost level
[%]
0.0 - 200.0 150.0 T PERCEN
T
- Float 2
The magnitude of the Hammer Start boost is calculated as follows:
V_HS = P0305 * Rsadj * (P3357 / 100)
Note:
Rsadj = stator resistance adjusted for temperature
Rsadj = (r0395 / 100) * (P0304 / (sqrt(3) * P0305)) * P0305 * sqrt(3)
Index: See P3350
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
resistance 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
1 - 10 5 C, T - - U16 2
The number of times the hammer start boost level (P3357) is applied.
Index: See P3350
P3359[0...2] Hammer on time [ms] 0 - 1000 300 T - - U16 2
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] 0 - 1000 100 T - - U16 2
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
frequency [Hz]
0.0 - 599.0 5.0 T - - Float 2
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
reverse time [s]
0.0 - 20.0 5.0 T - - Float 2
Sets the time for which the inverter runs in the opposite direction to the setpoint during the reverse
sequence.
Index: See P3350
P3363[0...2] Enable rapid ramp 0 - 1 0 T - - U16 2
Selects whether the inverter ramps to, or starts directly from, the blockage clearing frequency (P3361).
0 Disable rapid ramp for blockage clearing
