Cause of the Problem Solution
A
Incorrectly set Multi-Turn Limit
Setting parameter (Pn205) in the
servo amplifier.
Change the value in parameter
Pn205.
B
No Multi-Turn Limit value set in
the encoder.
First verify that the Multi-Turn
Limit Setting parameter (Pn205)
is set correctly in the servo ampli-
fier. While in the active alarm
state, change the setting in the
encoder Multi-Turn Limit Setting
parameter (Pn205) using function
Fn013.
