from either flash or Memory Card failed (checksum fault).
Check:
−
one or both parameter sets (User1 and / or User2)
have not been saved properly - see ApplMacro (99.08)
−
SDCS-CON-F
F551 551 AIRange
Analog input range:
Undershoot of one of the analog input values under 4mA /
2V. Check:
−
AI Mon4mA (30.29)
−
used analog inputs connections and cables
−
polarity of connection
9.04,
bit 2 always 4
F553 553 TachPolarity Tacho polarity:
The polarity of the analog tacho respectively pulse
encoder [depending on M1SpeedFbSell (50.03)] is
checked against the EMF. Check:
−
EMF FbMonLev (30.15), SpeedFbMonLev (30.14)
−
polarity of tacho cable
−
polarity of pulse encoder cable (e.g. swap channels A
and A not)
−
polarity of armature and field cables
−
direction of motor rotation
9.04,
bit 4 always 3
F554 554 TachoRange Tacho range:
Overflow of AITacho input. Check:
−
for the right connections (X1:1 to X1:4) on the SDCS-
CON-F
9.04,
bit 5 always 3
F557 557 ReversalTime Reversal time:
Current direction not changed before ZeroCurTimeOut
(97.19) is elapsed. Check:
−
for high inductive motor
−
too high motor voltage compared to mains voltage
−
lower RevDly (43.14) if possible and
−
increase ZeroCurTimeOut (97.19)
