Super torque boost level
[%]
0.0 - 200.0 150.0 T PERCEN
T
- Float 2
The magnitude of the Super Torque boost is calculated as follows:
V_ST = P0305 * Rsadj * (P3355/100)
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 converter.
Note:
The Super Torque 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 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

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.

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:

Up to 200% of rated motor current (P0305) or limit of converter.
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.

Note:
During this time, the boost level drops to the level defined by P1310 (continuous boost).
