11.2.10 Settings to Clear the Position Deviation

A position deviation in the HWBB state is cleared according to the setting of Pn200 = n.X
(Clear Operation). If you specify not clearing the position deviation during position control
(Pn200 = n.1), the position deviation will accumulate unless the position reference from
the host controller is canceled in the HWBB state. The following conditions may result.
• An A.d00 alarm (Position Deviation Overflow) may occur.
• If you turn ON the servo after changing from HWBB state to BB state, the Servomotor may
move for the accumulated position deviation.
Therefore, stop the position reference from the host controller while in the HWBB state. If you
specify not clearing the position deviation during position control (Pn200 = n.1), input the
CLR (Position Deviation Clear) signal during the HWBB or BB state to clear the position devia-
tion.

The ALM (Servo Alarm) signal is not output in the HWBB state. The ALO1, ALO2, and ALO3
(Alarm Code Output) signals are not output in the HWBB state.
