Setting
= 3: Enable blockage clearing 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.
If blockage clearing mode is enabled (P3350 = 3), make sure
that reverse direction is not inhibited, i.e. P1032 = P1110 = 0.
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 inverter runs
in the opposite direction to the setpoint during the blockage
clearing reverse sequence.
Range: 0.0 to 550.0 (factory default: 5.0)
This parameter sets the time for which the inverter runs in the
opposite direction to the setpoint during the reverse sequence.
Range: 0.0 to 20.0 (factory default: 5.0)
This parameter selects whether the inverter ramps to, or starts
directly from, the blockage clearing frequency
= 0: Disable rapid ramp for blockage clearing (use ramp time
specified in P3353)
= 1: Enable rapid ramp for blockage clearing (jump to the re-
verse frequency - this introduces a "kicking" effect which helps
to clear the blockage)
Range: 0 to 1 (factory default: 0)
This parameter sets the number of times the blockage clearing
reversing cycle is repeated.
Range: 1 to 10 (factory default: 1)
