KEB COMBIVERT F4-F, Quick Reference

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) .

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
