Setting
= 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.
This parameter defines the source of the super torque enable.
The setting is effective when P3352 = 2.
Factory default: 0 (never enabled)
This parameter defines when the super torque function be-
comes 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 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)
This parameter defines the number of times the hammer start
boost level is applied.
Range: 1 to 10 (factory default: 5)
This parameter sets the time for which the additional boost is
applied for each repetition (must be at least 3 x motor magneti-
zation time).
Range: 0 to 1000 (factory default: 300)
This parameter sets the time for which the additional boost is
removed for each repetition (must be at least 3 x motor magnet-
ization time).
Range: 0 to 1000 (factory default: 100)
