Cause
The reference point coordinate received
when adjusting the encoder via connector
input p2599 lies outside the half of the
encoder range and cannot be set as actual
axis position.
Fault value (r0949, interpret decimal):
Maximum permissible value for the refer-
ence point coordinate.
After the standstill monitoring time expired,
the drive left the standstill window.
Position loop gain too low.
•
Position loop gain too high (instabil-
•
ity/oscillation).
Mechanical overload.
•
Connecting cable, motor/drive convert-
•
er incorrect (phase missing, inter-
change).
When the position monitoring time (p2545)
expired, the drive had still not reached the
positioning window (p2544).
Positioning window parameterized too
•
small (p2544).
Position monitoring time parameterized
•
too short (p2545).
Position loop gain is too low.
•
Position loop gain is too high (instabil-
•
ity/oscillation).
Drive mechanically locked.
•
The difference between the position set-
point and position actual value (following
error dynamic model) is greater than the
tolerance (p2546).
The value of p2546 is too small.
•
The gain of position loop is too small.
•
The drive torque or accelerating capac-
•
ity exceeded.
Position measuring system fault.
•
Position control sense incorrect.
•
Mechanical system locked.
•
Excessively high traversing velocity or
•
excessively high position reference
value (setpoint) differences.
Remedy
Set the reference point coordinate to a lower
value than specified in the fault value.
See also: p2599 (EPOS reference point coor-
dinate value.
For a motor with an absolute encoder, the
maximum permissible encoder range is calcu-
lated by the following formula:
For multiturn encoders:
•
(4096 * p29247) / 2
For singleturn encoders:
•
p29247 / 2
