Operation with MultiTurn emulation
You can simulate the function of a Multiturn over the entire travel distance by the
aid of a Multiturn emulation. A resolver or a SinCos

/ EnDat Singleturn feedback is
sufficient as a feedback signal from the motor.
It differs from the physical Multiturn in the way that the motor may not be moved by
more than half a turn if Compax3 (24VDC) is switched off – unless the absolute
position is lost.
Besides that, the Multiturn emulation offers the same function as the physical Multi-
turn feedback.
You can switch on the Multiturn emulation directly in the wizard.
You can assign the maximum permissible motor angle via the Multiturn validity
window
If Compax3 states after switching on that this value is not exceeded, then
the"Referenced" is set status word Bit 12 or output M.O8).
Compax3 restores nevertheless the absolute position, the motor angle is correct,
the absolute position is however not correct, if the motor was moved by more than
the validity window while currentless.
For a unique machine zero run the same conditions apply as for the use of an ab-
solute encoder (Multiturn).
