| 3. Fault messages The red
"FAULT" lamp lights up in case of a fault. The fault is annunciated on the
display and the display flashes.
The safety guidelines must be noted prior to working on any
wiring or when replacing a unit (see doc.no. 209-0041-4109).
BLEEDER
Bleeder overload
- Bleeder monitor has been actuated because of overheating.
- The bleeder in the drive controller is defective or no bleeder is
installed.
Remedy
1. Check to see whether a bleeder resistor has been installed in the drive controller
(wire filament). If yes, then let the drive controller cool down for at least 15 minutes.
Then switch back on. If fault is still displayed, replace drive controller! Note the
safety guidelines when replacing a unit! Note the guidelines on handling the programming
module! ->See doc. no. 209-0041-4109-02!
- If the drive controller is not equipped with a bleeder resistor
(type designation ...-W1), then <256> has been incorrectly set in the value of
parameter FUNCT2 (A06).
Remedy
2. Reduce parameter value by 256! ->See doc. no. 209-0041-4109-02!

control inputs SPEED1 and SPEED2 (X2/35,36), see Figure 1.4).
Remedy
1. Replace drive controller.
2. Check contactor wiring and acknowledgement contacts for
compliance with the terminal diagram of INDRAMAT. ->See doc. no. 209-0041-4109-02!
NOMAINS
(only with RAC 3)
No mains voltage
No voltage at the mains terminals X14/L1,L2,L3 , or the voltage applied is too low.
Remedy
1. Check mains!
NO TEMP
Error in motor temperature detector
The connection between the thermistor of the motor and the drive controller is disrupted
or the thermistor is defective (this message comes approximately ten minutes after the
fault occurs).
Remedy
1. Check the thermistor connection. There are always two thermistors in 2AD and 1MB
motors. Only one can be connected to the drive controller!
2. Check thermistor: R20°C= approx. 40KOhm, R80°C=
approx. 3.5kOhm, R140°C= approx. 565 Ohm ±5 % each. If the measured values exceed this
range, replace thermistor, motor (2AD) or stator (1MB)!
NO 8V
8 V - Control voltage faulty
The internal 8V supply of the drive controller is disrupted.
Remedy
1. Replace drive controller!
NO 15V
15 V - Control voltage faulty
The internal ± 15V supply of the drive controller is disrupted.
Remedy
1. With the KDA/TDA, check whether bus connection cable for control voltage is firmly
in place. If fault is signalled, replace drive controller!
2. With an RAC, replace drive controller or call INDRAMAT
customer service!
NO 24V
24 V - Control voltage faulty
The internal ± 24V supply of the drive controller is disrupted.

There is no external application of voltage for the control and
signal outputs (X2/1 und 19), or these are incorrectly polarized or exceed tolerance
range.
Remedy
1. Check connection and voltage level of external +24V . The voltage level must range
between 18V and 36V. If the external +24V is in order, then the fault message should clear
of its own accord.
2. If there is no external +24V/0V, then the internal +24V/OV of
the drive controller can be used (apply bridge from +24Vint/OVint to +24Vext/ OVext
(connector X2)).
NO KDA
NO RAC2
NO RAC3
NO RAC4
NO TDA
Parameter M17 incorrectly programmed
Remedy
Reprogram parameter M17.

OVER VOLT
(only with RAC)
Overvoltage
The mains voltage exceeds the nominal voltage connection by more
than 15%. It is not possible to switch on the mains contactor in the unit.
Remedy
1. Check mains, transformer may have to be connected to adapt
mains voltage.
PARALOST
Data loss in parameter storage
There are no parameter values in the programming module. These were either cleared or not
stored.
Remedy
1. Move the operating mode switch to the left and press the red key. This loads general
base parameters which can set the drive in motion. If ‹BASISPAR" appears on the
display, then loading is completed. Pressing the red key again will bring the drive into
parameter mode. The base parameters are not optimal for the drive and should be replaced
by optimized values (AS../...) (supplied as part of the parameter protocol of the
programming module). ->See doc. no.209-0041-4109-02.
PHASE
(only with RAC 3)
There is no right-rotational field or one of the three phases is
missing (with RAC 3 only phase failure)
Remedy
1. Check mains
POS ERROR
Positioning error
Lag error monitor has been actuated during spindle positioning with spindle reference
switch. Drive cannot comply with position command value.
Remedy
1. Check spindle for jamming, sluggishness and defects in the coupling component.
2. Check whether torque reduction of the drive is active (+24V at
control input MD-RED (X2/28), see Figure 4)!
3. Reduce positioning speed POSRPM with a lesser value in parameter
P18, Q18, R18 or S18! ->See doc. no. 209-0041-4109-02!
