GB-23
Display Significance
noP No Operation; term. X2.1 (control release) is not assigned.
LS Low speed; control release is set, no direction of rotation
selected, modulation off.
Facc Forward acceleration; acceleration phase forward.
Fcon Forward constant running; constant drive forward.
Fdec Forward deceleration; deceleration phase forward.
racc Reverse acceleration; acceleration phase reverse.
rcon Reverse constant running; constant drive reverse.
rdec Reverse deceleration; deceleration phase reverse.
bbl Base-block-time; power modules are locked for 3s (always,
if control release is switched off or when an inverter error
occurs) .
a) Running Messages
Inverter State
Operating Parameter
Display Significance
E.buS Error, bus, failure in serial communication
E.dOH Error, drive-overheat, motor overheats and prewarning
time has run out
E.dSP Error, digital signal processor, error in signal processor
E.PrF Error, prohibited rotation forward, error in the software
limit switch (when the set direction of rotation is forward,
the software limit switch for forward is inactive)
E.Prr Error, prohibited rotation reverse, error in the software
limit switch (when the set direction of rotation is reverse,
the software limit switch for reverse is inactive)
E.hyb Error, hybrid, error in the encoder input card
E.EnC Error, encoder, error in the encoder break (reset only
possible with Power-On-Reset)
E.LSF Error, load shunt fault
E.OC Error, overcurrent, overcurrent short-time peak overloading
E.OH Error, overheated, overheating of the inverter
E.OH2 Error, overheat 2, electronic motor protection
E.nOH Error, no overheat, overheating no longer preset, can be
reset (valid for malfunction E.OH or E.OH2)
E.OL Error, overload, continuous overload, for cooling down
the inverter has to stay supplied with power, the cooling
time depends on the previous overload time
E.OL2 Error overload, overloading of the inverter at output
frequency < 3 Hz
E.nOL Error, no overload, cooling time has run out, error can be reset
E.OP Error, overpotential, overvoltage in the DC voltage circuit
E.OS Error, overspeed, overspeed (can only be reset with
power-on-reset)
E.PuC Error, power unit code, invalid power circuit recognition
E.SEt Error, set, set selection error, check LF.02
E.UP Error, underpotential, undervoltage im DC voltage circuit
