18) Perform setups for the remaining axes from Step 1 in the same manner as above.
CautionFY1 and RY1 as well as RY2 and FY2 can be set simultaneously.
However, FY1 and FY2 as well as RY1 and RY2 must not be set
simultaneously.
Prerequisite for magnetic estimation:
1: Set the Pr9.20 to 2.
2: Magnetic estimation has never been performed after rebooting
the AMP.
3: The Servo must be turned on.
4: If even one of the above requirements is not satisfied, magnetic
estimation cannot be performed.

12.5. New Dual Head Amp Driver
12.5.1. Alarm Code
When an error occurs, the 7 segment LEDs of the motor drive will flicker. As well, the
corresponding alarm code is generated. It is of “Err **” form and the “**” will express the
corresponding alarm code.
In this case, take measures against the corresponding alarm code referring to the following
