・During absolute position control, turning on the input terminal
085[PSET] sets the current position to the value set in [AE-62]
pre-set position data.
The current position monitor [dA-20] is also changed.

・Set the Homing function for absolute position mode.
・When using the homeing function, assign the input terminal
080[ORL] Limit signal of homing function and 081[ORG] Start
signal of homing function.

・DB function can be activated at start-up and stop state
([AF101]=01) or at setting frequency ([AF101]=02), selectively.
・DC braking can be also used if Intelligent input terminal
030[DB] is ON.
*2) Depending on the setting of Load type selection [Ub-03] and
inverter capacity, an internal limit is applied to DC braking
force.
・Stop DB example (Braking force adjusted by [AF105])
・Start DB example (Braking force adjusted by [AF108])
・Frequency reference DB example (Braking force adjusted
by [AF105])
・When the DC braking time is set as 0.00(s), DC braking is
not operational.
