O.ERR_11
SyncPos
Axis no. 1 Software limit switch activated
Cause
A motion command will cause / has caused the
software limit switch to be activated.
Tip
Identification of attainment of software limit at a
motion in the speed mode will only be made after
the current position is identical to the software limit
switch.
The control unit will be switched off and the drive
must be manually moved back to within the
admissible area, or the monitoring of the software
limit switch must be temporarily de-activated via
the axis parameter SWPOSLIMACT (20) resp.
SWNEGLIMACT (19). Only then is it possible to
clear the error.
In positioning mode, it will be known before motion
start that the target position lies outside the path.
In this case, the movement will not be executed
and the error message can be cleared.
O.ERR_12
SyncPos
Illegal parameter number
Cause
An attempt has been made to change a parameter
(SET or SETVLT command), which does not exist.
O.ERR_13
SyncPos
VLT ERROR (STATUS)
Cause
VLT is not ready but the PID controller is active. The
VLT status word (Bit 09 and bit 11) is monitored
every 20msec when the PID controller is active
(MOTOR ON state). There is no monitoring in
MOTOR OFF state or when parameter 700 is set to
"Disable Syncpos".
The VLT is in the "Not ready" state when:
•
it has an alarm,
•
it is in local mode (parameter 002 = local),
•
local LCP stop is activated,
•
there is no signal on input 27 (coast).
O.ERR 13 can only be reset using the ERRCLR
command or with "Break" [Esc] in the PC software
and only when the VLT is in the "ready" state, which
means none of the above may be true.

VLT ® 5000 SyncPos option
Note
O.ERR 13 will show up right after power up if the
VLT is not ready.
O.ERR_14
SyncPos
Too many nested loops
Cause
Too many nested loops exist in the executed
program.
O.ERR_16
SyncPos
Parameters in EEPROM are corrupted
Meaning
The parameters in EEPROM are no longer correct.
Cause
EEPROM defective or
power outage while saving.
Tip
You have to re-initialize the parameter with
"CONTROLLER" → "PARAMETERS" → "RESET"
and then overwrite these parameters with your own
user parameters. Otherwise motion programs
which require user parameters will no longer
function correctly.
O.ERR_17
SyncPos
Programs in EEPROM are corrupted
Meaning
The program data stored in EEPROM cannot be
found resp. are no longer correct.
Cause
EEPROM defective or
power outage while saving.
Tip
Delete the EEPROM with "CONTROLLER" →
"MEMORY" → "DELETE EEPROM" and then re-
load the programs and parameters.
