P602
M pre-control time
After the pulse enable is given this time is started. After this time is run up the "ready for use"
relay is enabled. This is independent wether the intermediate circuit voltage has reached the
desired Uzk set value (P087 Uzk nominal).
P610
MM Uzk actual
Actual value of the intermediate circuit voltage.
P611
MM Uzk actual smoothed
Actual value intermediate circuit voltage smoothed. The smoothing time constant of a digital
PT1 can be set in parameter P612 (MM Uzk smoothing time).
P612
MM Uzk smoothing time
To reduce interferences on the intermediate circuit voltage actual value a smoothing constant
of a digital PT1 can be set here.
P616
BUC control word
This parameter displays the state of the PLL.
P617
MM CC counter
The no. of whole control periods (control tasks) are count here. The counter "CC counter" is
incremented with each control period. While comparing with the last maximum mains period
value, an exceed of the jitter limit is checked. In this case, the error counter increases and the
previous mains period value is used. Therefore the internal value of the mains angle increa-
ses steadily.
P618
MM period time mains
The measured mains period is displayed.
P619
MM period smoothed
The smoothed value of the mains period is displayed. The smoothing can be set with P620
(MM PLL display filter).
P620
MM PLL display filter
The measured duration of the mains period is smoothed and displayed here.
Bit no. Meaning
0 0 : PLL catch phase
1 : normal run after PLL caught
1 1 : set, when PLL not caught
2 1 : set, when no error
3 1 : error in current controller
