Starting the motor in super torque mode

Functionality
This startup mode applies a torque pulse for a given time to help start the motor.
Typical application field
Sticky pumps

Setting
= 1: Enable super torque mode
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 parameter defines the source of the super torque enable. The set-
ting is effective when P3352 = 2.
Factory default: 0 (never enabled)
This parameter 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 (enable source is defined by P3351; 0 =
never enabled, 1 = enabled on every run)
This parameter defines the ramp time to be used when ramping up to
the super torque frequency.
Range: 0.0 to 650.0 (factory default: 5.0)
This parameter defines the frequency at which the additional boost is
applied for super torque mode.
Range: 0.0 to 550.0 (factory default: 5.0)
This parameter sets the temporary boost level for super torque mode.
It applies boost in [%] relative to P0305 (rated motor current) once the
super torque frequency has been reached for the time specified in
P3356.
Range: 0.0 to 200.0 (factory default: 150.0)
This parameter sets the time for which the additional boost is applied,
when the output frequency is held at P3354.
Range: 0.0 to 20.0 (factory default: 5.0)
