PNU Description
P826 Correction of natural commutation timing
(G163) If there is a variation in the armature current peak value (in spite of a
constant firing angle), it can be corrected by offsetting the firing angle
reference time of the appropriate line phase in parameter P826. One line
phase (UV, UW, VW, VU, WU, WV) is assigned to each parameter index
(i001 to i006).
Increasing the parameter setting by a value of 1 corresponds to an increase
of 1.333 µs in the firing angle (0.024 degrees at 50Hz line frequency),
consequently reducing the armature current peak in the appropriate line
phase.
P826 is automatically set during the optimization run for precontrol and
current controller (armature and field) (P051=25) (only when U800=0; when
U800=1 or 2, parameters P826.001 to 006 are set to 0).
Caution:
Even an asymmetrical system causes variations in the magnitude of
armature current peaks. However, the system asymmetry may also change.

11.44 Thyristor diagnosis
P830 Control word for thyristor diagnosis
*
0 Thyristor check function deactivated
1 Thyristors are checked on initial SWITCH-ON or INCHING
command after connection of the electronics supply voltage.
2 Thyristors are checked on every SWITCH-ON or INCHING
command.
3 Thyristors will be checked on the next SWITCH-ON or INCHING
command. Parameter P830 is set to 0 if no fault is detected.
Note:
The thyristor check function may not be activated (setting P830=0 must be
selected)
−
when the "Enable a torque direction for torque direction change by
parallel drive" function is in use (see also parameter P165) or
−
when the converter is used to supply large inductances (e.g. field supply
from armature terminals, supply of lifting solenoids, etc.).
