Parameter assignment error
Parameter assignment error Response of the 1PosU
Causes:
• The 1PosU cannot identify existing parameters as its
own.
• The slot of the 1PosU you have configured does not
match the setup.
Only at SSI encoder:
• Impermissible value for parameter for number of
increments.
• Impermissible value for parameter for number of
rotations.
• Number of increments * number of rotations is
greater than 4096x4096.
Only at SSI encoder:
• Activated "Encoder signal" diagnostics
• Activated "Reversal of the direction of rotation"
What to Do:
• Check the configuration and setup
• The 1PosU is not assigned parameters and cannot execute
its functions.
• Generate channel-specific diagnostics
