Error cause
M S
913
DC: U_DC>U_BC
Fault:
at a standstill, the voltage measured at the intermediate circuit (+DC/-
DC) after 5 s is higher than trigger voltage U_BC
Remedy:
Defective analysis of the DC-link voltage U_DC
The synchronous motor is operated without motor contactors and driven by an
external load
●
914
X-ENC15:Miss.
Fehler:
Bei Einschalten des Umrichters wird kein Geber an X-ENC 15 erkannt
Remedy:
Check encoder connection
reset the inverter
916
X_ENC15:Discon.
Error:
Interruption of the encoder signal during travel
Remedy:
Check encoder connection
Switch frequency inverter off and then back on
917
BRxx activ
Error:
The internal Transistor for the brake resistor is still triggered 5,5 s after
travel-end
●
918
MP:Temp.missing
Error:
Temperature detector on power stage is not supplying any measure-
ments
Remedy:
Change the device
Check fuse on SP board
●
919
ZR:ERR by opera.
Error:
Signal at BC input drops out during travel
Remedy:
Use the ZArec display to check for an error at the ZArec
920
MOP:ERRNMI active
Error:
Overcurrent during standstill
Remedy:
Check the brake chopper / brake resistor wiring
●
930
MP: UCE Alarm BR
Error:
The voltage monitoring of the transistor of the Brake resistor has
triggered (Overcurrent of the electric circuit of the Brake resistor)
Remedy:
Check wiring of the Brake-Resistor
Check Brake-Resistor
Check whether the correct type is con
fi
gured in the "Encoder & BC/BC_Typ"
menu
●
931
MP:ERR_EXT active
Error:
internal error message of the output stage
Remedy:
Switch frequency inverter off and then back on
Replace the device (only after consulting the ZIEHL-ABEGG hotline)
●
950
TD_CNT: Drive Limit
Error:
Number of maximum drives reached!
Only one travel with the actual rope remains.
Remedy:
Change ropes and reset the down counter.
After resetting the ZETADYN 3 there is one additional drive possible.
●
991
MOP: Timeout
Error:
The communication between the processors was interrupted or the
communication between the processors is faulty during travel.
Remedy:
Make sure that the EMC regulations are observed (see chapter
"Electrical Installation / EMC-conform Installation")
●
●
994
MOP: Timeout 2
Error:
I standstill the communication between the Motor-Management-Pro-
cessor (MOP) and the Application-Processor (APP) is interupped for more than
7.5 s
Increased BR-protection
●
995
ENC:1387 CD-Lim
Fault:
signal track C and/or D of absolute value encoder type ERN1387
exceeds permitted limit value before travel starts
Remedy:
Check the encoder,
Check the optional pcb for encoder connection
Fault can only be reset once the frequency inverter is switched off
