Error Assistance
4. Error Assistance
At KEB COMBIVERT error messages are always represented with an "E." and the appropriate error in the
display. Error messages cause the immediate deactivation of the modulation. Restart possible only after reset or
autoreset.
Malfunction are represented with an „A.“ and the appropriate message. Reactions to malfunctions can vary. In the
following the display and their cause are described.

Status Messages
bbL
base block
76
Power modules for motor de-excitation locked
bon
close brake
85
Brake control, brake engaged (see chapter 6.9)
boFF
open brake
86
Brake control, brake released (see chapter 6.9)
Cdd
calculate drive
82
Measurement of the motor stator resistance.
dcb
DC brake
75
Motor is decelerated by a DC-voltage at the output.
dLS
low speed / DC brake
77
Modulation is switched off after DC-braking (see chapter 6.9 "DC-
Braking“).
FAcc
forward acceleration
64
Acceleration with the adjusted ramps in clockwise direction of rotation.
Fcon
forward constant
66
Acceleration / deceleration phase is completed and it is driven with
constant speed / frequency in clockwise direction of rotation.
FdEc
forward deceleration
65
It is stopped with the adjusted ramp times in clockwise direction of
rotation.
HCL
hardware current limit
80
The message is output if the output current reaches the hardware
current limit.
LAS
LA stop
72
This message is displayed if during acceleration the load is limited to the
adjusted load level.
LdS
Ld stop
73
This message is displayed if during deceleration the load is limited to the
adjusted load level or the DC-link current to the adjusted voltage level.
LS
low speed
70
No direction of rotation pre-set, modulation is off.
nO_PU power unit not ready
13
Power circuit not ready or not identified by the control.
noP
no operation
0
Control release (terminal ST) is not switched.
PA
positioning active
122 This message is displayed during a positioning process.
PLS
low speed / power off
84
No modulation after Power-Off.
PnA
position not reachable
123 The specified position cannot be reached within the pre-set ramps. The
abort of the positioning can be programmed.
POFF
power off function
78
Depending on the programming of the function (see chapter 6.9 „Power-
off Function) the inverter restarts automatically upon system recovery or
after a reset.
POSI
positioning
83
Positioning function active (F5-G).
rAcc
reverse acceleration
67
Acceleration with the adjusted ramp times in anti-clockwise direction of
rotation.
rcon
reverse constant
69
Acceleration / deceleration phase is completed and it is driven with
constant speed / frequency in clockwise direction of rotation.
rdEc
reverse deceleration
68
It is stopped with the adjusted ramp times in anti-clockwise direction of
rotation.
rFP
ready for positioning
121 The drive signals that it is ready to start the positioning process.
SLL
stall
71
This message is displayed if during constant operation the load is limited
to the adjusted current limit.
SrA
search for ref. active
81
Search for reference point approach active.
SSF
speed search
74
Speed search function active, that means that the inverter attempts to
synchronize onto a running down motor.
STOP
quick stop
79
The message is output if as response to a warning signal the quick-stop
function becomes active.
