5. Press the MODE/SET key, and the following display will flash for one second.
The reference offset will be automatically adjusted.

7.2.4 Manual Adjustment of the Speed and Torque Reference Offset
Manual speed/torque reference offset adjustment is useful in the following
situations:
• If a position loop is formed with a host controller and the error zeroed-out when
the motor was stopped in servo lock (zero reference).
• To deliberately set the offset to some value.
This mode can also be used to check the data set in the Automatic Reference Offset
Adjustment Mode.
In principle, this mode operates in the same way as the Automatic Reference Offset
