Closed-loop thyristor current control
System- and communication configuring D7-SYS - SIMADYN D 5-13
Edition 06.2002
PA6. Significance Value\connection
AD
Hardware address
SYX
Mode: Synchronizing voltage source
(normally, phase L1 is used)
SYX=0: Internally via the SITOR interface (ITDC-X7:18,34)
SYX=1: Externally via connector (ITDC-X5:5)
(Initialization connection/
default: 0)
ZPA
Firing pulse number
No. of the active main pulse for the active torque direction.
PC6.ZPA
→ PA6.ZPA
{ 1
…6 }
XDA
Offset angle
of the specified angle corrects the phase shift between the natural
firing instant of semiconductor device 1 and
the zero crossover of the filtered synchronizing voltage (ITDC)
e.g. XDA=0.0
⇒ AVW = -30 [°]
XDA=10.0
⇒ AVW = -20 [°]
Offset angle and natural firing instant (
α=0°):
(Default: 0.0)
{ -180°
…+180° }
NAZ
Number of failed line supply periods of the synchronizing voltage
until a signal is output
Condition: 0
≤ PA6.NAZ ≤ 3050, otherwise, QSF\bit 9 = 1
(Initialization connection/
default: 8)
NEP Number of line supply periods until the system can be considered
to have stabilized and can be switched-on
Condition: 0
≤ PA6.NEP ≤ 5000, otherwise, QSF\bit 9 = 1
(Initialization connection/
default: 5)
NCM
Mode : Line supply handling (also refer to FAM connector)
Correction of the counter value of the line supply value (period
duration and phase) before the result is transferred to
FB-PC6.
0 = the line supply value is not handled
1 = refer to NCM=4
2 = the average value is generated from the last (max.8) line
supply values, the number of which is defined at FAM
3= line supply value fluctuation are corrected using the PLL
method (P controller). The phase difference is only taken into
account with 1/FAM.
4 = line supply value fluctuations are corrected using the PLL
method (PI controller). The phase difference is only weighted with
1/FAM and the last average with (FAM-1)/FAM.
(NCM > 0 is used for weak line supplies or if the synchronizing
voltage is polluted.
For single synchronizing voltage disturbances, the best suitable
setting is NCM=4 with FAM=20

For NCM=1: Refer to 4
For NCM=2: Number of saved line supply periods to generate the
average value
For NCM=3: Factor to reduce a measured phase difference
For NCM=4: Factor to reduce a measured phase step
