Power Supply Unit Support: -A new positioning command value x(k+1) is specified during the positioning of the drive guide, during which the drive moves to the target position of the last positioning command value x(k). The new positioning command values are saved in the input buffer (positioning default value memory) and are deleted as soon as they are received.
Cause: An attempt was made to specify a new position command value x(k+2) while the drive was moving to the target position of the positioning command value x(k).
The erroneous rating reception in the control unit (triggered by S-0-0346, Positioning Control Word) results in the specified positioning command value being received multiple times.
When "Driving to Target Location", S-0-0346, the positioning mode in the positioning control word is set incorrectly.
Workaround: Check the rated default value in the control unit to ensure that the new position command value x(k+2) is specified when the positioning command value x(k+1) is received and the drive unit is driven to the target position to which it belongs
Check the control program, via S-0-0346, the position control word always triggers bit 0 only once for each new position command value, because each bit change is received by the position command value being used.
When "Driving to Target Location", set the positioning mode "Immediately Driving to a New Target" in the S-0-0346, Positioning Control Word
