Baumüller Nürnberg Electronic GmbH & Co. KG 5.03047.01
P621 MM mains frequency
Display of the measured mains frequency.
P622 MM no. of mains faults
No. of not successful mains synchronisations because of faults. Reaches the error counter
the value 5, the bit no. 1 in P616 (BUC control word) is set, the drive manager disables the
controller and the error 0x0503 is generated.
P623 MM mains jitter
Set/actual deviation of 2 successive mains values (deviation of period length, display in de-
grees).
P624 MM mains jitter limit
If the absolute value of the phase deviation during synchronisation to the mains is below the
set mains jitter limit, the period time is new calculated and therefore all angles until the next
occurance are calculated. Moreover the error counter P622 (MM no. of mains faults) is de
-
cremented until min. zero. If the absolute value is higher than the mains jitter limit, the error
counter is incremented (until max. 5) and when the controller is enabled (state 3 and 4) the
error 0x0503 is generated. If the controller is disabled, the controller changes from state 9 to
state 2. The signal of the function output 2 (X26:22, see chapter 4.4 - terminal diagram V-
controller) "ready for pulse enable" changes from high to low.
P625 MM Rho offset
Because of the phase shift when measuring the "SYNC" signal a correction value is added
thereby the transformation angle is mains synchron. The parameter must be set in this way,
that P076 (Ud set value) is equal zero, when controller is enabled.
P626 MM Rho
Actual value of the mains angle (transformation angle).
Internal standardization: ± 180 degrees ↔ ± 32767
