Error Displays of a CTA Programming and
Display Unit
If the DLC 1 detects an error, then this error will be signalled in the CTA dis-
play. All system outputs and outputs 01 through 72 are cleared.
Errors are stored. Once the fault has been cleared, the error message must
then be cancelled with the CL key or by a 1-signal at the CLEAR input of the
DEA 4.

Error Description
Notes
Failure
absolute encoder error 1
No longer in the measuring range of the
absolute encoder of axis 1
• check the machine
• reduce the distance to be covered
Failure
axis shutdown 1
An axis not yet released has been called up
in the program
Check the program;
press until „F: Progr. Status“ appears; faulty
set is displayed
Failure
incorrect axis number
An axis not yet released has been called up
in the program
Check program;
press until „F: Progr. Status“ appears; faulty
set is displayed
Failure
drive watchdog
Synchronization of DLC and
drive controller is faulty
Replace DLC. If fault not cleared
- replace drive controller
Failure
battery empty
Back up battery for RAM storage is almost
empty -- data could be lost
Replace battery!
Failure
operating mode
Input parameters and automatic are on 1
Place input parameter or automatic to 0.
Failure
division error
Parameter not valid
Check parameters!
Failure
DPR not legible
Data exchange between DLC and drive
interrupted during intialization
Replace DLC. If fault still present, replace drive.
Failure
storage set no.
The previously programmed program set is
faulty.
Check the respective program.
Failure
external encoder
Signals of the external path measuring
systems are faulty
• Check encoder lead
• Lag between motor and external encoder
• DEF defective
input error
Parameter A100
The parameter indicated was incorrectly
programmed
Check parameters!
Failure
HOM command A1
HOM command not possible. Go to zero not
released.
Parameter A110 und A112 prüfen (Achse 1)
Failure
IDS break error
Verbindung zu den Dekadenschaltern ist
unterbrochen oder gestört.
Check lead
(interruption, max. length 15m)
Failure IDS
format length
DLC receiving faulty data format.
Check lead, max. length 15m;
Check shield.
Failure
IDS format symbol
DLC receiving faulty data format.
Check lead, max. length 15m;
Check shield
Failure IDS
checksum error
DLC receiving faulty data format.
Check lead, max. length 15m;
Check shield
Failure
Illegal command
User program contains illegal command,
e.g., REP without REF command.
check program
press until „F: Progr. Status“ appears; faulty
set is displayed
Failure
JSR nesting
nesting depth of subprogram > 127.
• check program
• jump to subprogram without return jump (JSR
without RTS)
Failure
no BCD Input
the value for a jump command at inputs 1
through 8 is not in BCD format
check inputs 1 through 8
input
8 7 6 5 | 4 3 2 1
value
80 40 20 10 | 8 4 2 1
input
<100
|
<10
Failure
configuration
configuration of the interface assembly in
the drive controller is not permitted

Failure
no zero impulse 1
the zero impulse of an external position
encoder cannot be recognized
• check the position of the reference switch
• check the connection to the external position
encoder
