■ ■ ■ ■ ■ SyncPos option messages in detail
As in the table above, the messages are in numeri-
cal order. Here you can find additional information
about possible causes and tips on troubleshooting.
O.E R R_3
SyncPos
Axis no. %bu not in system
Cause
An attempt has been made to find another axis
which does not exist in the controller. (The program
allows for input of axis numbers greater than 1
since it is configured for multi-axes applications.)
Tip
Check to see if the program axis command has an
invalid number or a general axis command (...X(*)).
O.E RR_5
SyncPos
Axis no: 1 - Error not cleared
Cause
An attempt has been made to execute a motion
command, although a momentary error message
has not been cleared.
O.E RR_6
SyncPos
Axis no: 1 - Failed to move to HOME position
Cause
According to the axis parameter HOME_FORCE
(3), a forced move to the machine zero-point is de-
manded, before other motion commands can be
executed. This move to the machine zero-point has
not been executed.
O.E RR_7
SyncPos
Axis no: 1 - Home vel 0
Cause
HOME was executed with HOME_VEL set to zero.
MG.10.J8.02 – VLT is a registered Danfoss trade mark
Programmable SyncPos motion controller
O.E RR_8
SyncPos
Axis no: 1 - Position error
Meaning
The distance between the set and the real position
was greater than the T T T T T olerated position error olerated position error olerated position error olerated position error
olerated position error
defined in parameter POSERR (15).
Cause
Mechanically blocked or overloaded drive,
T T T T T olerated position error olerated position error POSERR (15) too small, olerated position error olerated position error olerated position error
commanded speed greater than VLT Parameter
202 and 205,
commanded acceleration too great,
Proportional factor Proportional factor Proportional factor Proportional factor Proportional factor KPROP (11) too small or
VLT not enabled.
O.E RR_9
SyncPos
Axis no: 1 - Index pulse (encoder) not found
Meaning
At reference resp. index search, the encoder index
pulse could not be found within a motor rotation.
Cause
An encoder without an index pulse has been used,
index pulse not connected correct,
index pulse incorrect (all three channels must have
a simultaneous low) or
the parameter ENCODER (2) is set too low.
O.E R R_10
SyncPos
Unknown command
Cause
A communication or program error.
Tip
The program must be re-compiled and re-loaded.
