Note: When the value of P3350 is changed, the value of P3353 is changed as follows:
•
P3350 = 2: P3353 = 0.0s
• P3350 ≠ 2: P3353 = default
The ramp time of 0s gives an additional 'kicking' effect when hammer start is in use.
This setting can be overridden by the operator.
If blockage clearing mode is enabled (P3350 = 3), make sure that reverse direction is not inhibited, i.e.
P1032 = P1110 = 0.
P3351[0...2] BI: Super torque enable - 0 T - CDS U32 /
Bin
2
Defines source of the super torque enable when P3352 = 2.
Dependency: Applies only when P3352 = 2.
P3352[0...2]
Super torque startup
mode
0 - 2 1 T - - U16 2
Defines when the super torque function becomes active.
0 Enabled on first run after power-up
1 Enabled on every run
2 Enabled by digital input
Index: See P3350
Dependency: If P3352 = 2, enable source is defined by P3351
P3353[0...2]
Super torque ramp time
[s]
0.0 - 650.0 5.0 T - - Float 2
Defines the ramp time to be used for all super torque functions. Overrides the P1120 / P1060 when
inverter is ramping to super torque / hammer start frequency (P3354) or the blockage clearing frequency
(P3361).
Index: See P3350
Dependency: The value of this parameter is changed by the setting of P3350.
See the description of P3350.
P3354[0...2] Super torque frequency
[Hz]
0.0 - 599.0 5.0 T - - Float 2
Defines the frequency at which the additional boost is applied for super torque and hammer start modes.
Index: See P3350
P3355[0...2] 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 inverter.
