F2050 Overflow of target position preset memory

Cause
There was an attempt to preset a new positioning
command value x(k+2) while drive was moving to
target position of positioning command value x(k)
Incorrect command value acceptance (toggling of
S-0-0346, Positioning control word) in control unit
causes positioning command value to be accepted
several times
Incorrect positioning mode for "approaching target"
was set in S-0-0346, Positioning control word

Note: If the control voltage is switched off after the battery was
removed, the absolute position data reference gets lost. The
position data reference then has to be reestablished.

Display: F2048
Mess. no.: F2048 (hex)
Supported by Firmware Variant:
In the case of drive-controlled positioning it is possible to preset a new
positioning command value x(k+1) while the drive is moving to the target
position of the last positioning command value x(k). The new positioning
command value is stored in an input buffer (target position preset
memory) and is not cleared until it has been accepted.
Remedy
Check command value in control unit and make sure
that new positioning command value x(k+2) is only
preset when positioning command value x(k+1) was
accepted and drive moves to corresponding target
position
Check control program and only toggle bit 0 of
S-0-0346, Positioning control word once for each new
positioning command value, because every change of
the bit causes current positioning command value to be
accepted
Set positioning mode "immediately moving to new
target" for "approaching target" in S-0-0346,
Positioning control word
