Additional Alpha W pulses with enabled second pulses
[SW 1.9 and later]
Number of additional Alpha W pulses with enabled second pulses after
detection of I=0 message prior to a change in torque direction.
It is particularly important to set this parameter to values of > 0 for converter
armatures which supply large inductances (e.g. lifting solenoids).
These pulses cause the current to decay before a change in torque
direction; the thyristors are fired in pairs to prevent sudden chopping, and
the generation of a surge voltage by the load inductor, when the current
drops below the thyristor holding current.
When a change in torque direction is required, the current in the existing
direction must be reduced.
This is achieved in the following ways:
If P179 > 0:
1) Alpha W pulses with enabled
second pulses
until the I=0 signal arrives
2) Additional Alpha W pulses with enabled
second pulses
(number as set in P179.F)
3) Additional Alpha W pulses with disabled
second pulses
(number as set in P161.F)
4) Additional torque-free interval (period as set in P160.F)
If P179 = 0:
1) Alpha W pulses with disabled
second pulses
until the I=0 signal arrives
2) Additional Alpha W pulses with disabled
second pulses
(number as set in P161.F)
3) Additional torque-free interval (period as set in P160.F)

Filter time for setpoint for armature current precontrol
[SW 1.9 and later]
Filtering of the armature current setpoint at the input of the precontrol for the
armature current controller.
The purpose of this filter is to decouple the armature current precontrol from
the armature current controller.
