5.6.3.2 Starting the motor in hammer start mode
Functionality
This startup mode applies a sequence of torque pulses to start the motor.
Typical application field
Very sticky pumps
Setting parameters
Parameter
Function
Setting
P3350[0...2] Super torque modes = 2: Enable hammer start 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.
P3351[0...2] BI: Super torque enable This parameter defines the source of the super torque enable. The setting is
effective when P3352 = 2.
Factory default: 0 (never enabled)
P3352[0...2] Super torque startup mode 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)
P3353[0...2] Super torque ramp time [s] 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)
P3354[0...2] Super torque frequency [Hz] This parameter defines the frequency at which the additional boost is ap-
plied for super torque mode.
Range: 0.0 to 550.0 (factory default: 5.0)
P3357[0...2] Hammer start boost level [%] This parameter sets the temporary boost level for hammer start 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)
P3358[0...2] Number of hammer cycles This parameter defines the number of times the hammer start boost level is applied.
Range: 1 to 10 (factory default: 5)
P3359[0...2] Hammer on time [ms] This parameter sets the time for which the additional boost is applied for
each repetition (must be at least 3 x motor magnetization time).
Range: 0 to 1000 (factory default: 300)
P3360[0...2] Hammer off Time [ms] This parameter sets the time for which the additional boost is removed for
each repetition (must be at least 3 x motor magnetization time).
Range: 0 to 1000 (factory default: 100)
