InternalLim
(P18)
x168 Internal limitation
Data generated by calculations of the 9300 servo positioning controller cannot be varied
arbitrarily. If the value falls below or exceeds the internal limit value the warning “P18” will be
set and the value is limited to the minimum or maximum.
C1298 = 1:
The negative position limit in C1223 is outside
the possible display range of
1
≤ (C1223∗ C1205) ≤ 1.07E9 incr
Check the entries under C1202-4, C1207/1.2.
If necessary, read the value decreased in the
event of a fault under C1220/10 and overwrite
the value entered under C1223.
C1298 = 2:
The positive position limit in C1224 is outside
the possible display range of
1
≤ (C1224∗ C1205) ≤ 1.07E9 incr
Check the entries under C1202-4, C1207/1.2.
If necessary, read the value decreased in the
event of a fault under C1220/11 and overwrite
the value entered under C1224.
C1298 = 3:

Check the entries under C0011, C1202-4,
C1207/1.2. If necessary, read the value decrea-
sed in the event of a fault under C1220/12 and
overwrite the value entered under C1240.
Adapt the value under C1240 to C0011.

Check the entries under C1202-4, C1207/1.2.
If necessary, read the value decreased in the
event of a fault under C1220/13 and overwrite
the value entered under C1250.
C1298 = 5:
An internal value range has been exceeded for
a speed normalization. Valid range:

ContourErrRC
(P21)
x171 Contouring error RC Phase difference between set and actual
position is larger than the contouring error limit
set under C1328.
Extend contouring error limit with C1328. If
necessary, switch off the monitoring
(C1329=3).
ProgInterfer
(PEr)
x074 Program error A fault in the program was detected. Send controller with data (on diskette) to
Lenze.
InitialErr
(PI)
x079 Initialising error • A fault was detected during transfer of
parameter set between the controllers
• Parameter set does not match controller.
Correct parameter set.
ParaSetErr
(PR)
x075
x072
Parameter set error Fault when loading a parameter set.
CAUTION:
The factory setting loaded automatically.
• Set the required parameters and store them
under C0003.
• For PRO the supply voltage must be
switched off additionally.
Resolve rFault
(Sd2)
x082 Resolver error Resolver cable interrupted. • Check the resolver cable for open circuit
• Check resolver.
• or switch off monitoring (C0586 = 3).
EncFaultCable x083 Encoder error at X9/8
Cable interrupted. Check cable for open circuit.
(Sd3)
Input X9 PIN 8 not assigned. Assign input X9 PIN 8 with 5V or switch off
monitoring (C0587 = 3).
MastlSourcDef
(Sd5)
x085 Master current source de-
fective
Master current at X6/1 X6/2 < 2mA. • Check cable for open circuit.
• Check master current source.
SensorFault
(Sd6)
x086 Sensor error Encoder of the motor temperature detection at
X7 or X8 indicates indefinite values.
Check supply cable for firm connection.
Switch off monitoring with C0594 = 3 if
necessary.
EncoderFault
(Sd7)
x087 Encoder error Absolute encoder with RS485 interface does
not transmit data.
Check supply cable.
Check encoder.
Check voltage supply C0421.
