31-1 The following 2 usage methods exist.
Exercise care in using either one.
Encoder Position at Power Cut-off (lower
2 words) 2
Enabled when either the fixed motion
parameter Encoder Selection is set to
Absolute Encoder (= 1), or the fixed
motion parameter Axis Selection (Bit 5 of
the Motion Controller Function Selection
Flag) is set to Rotary Axis = 1.
When the ABS system rotary position
management data LOAD request (Bit 2 of
OWC02D) is ON, the data set in this
parameter is handled as the lower 2
words of the encoder position at power
cutoff.
Position Buffer Access Number
The position data set in this parameter is
handled as the position buffer number
when either the Position Buffer Write (Bit
14 of OWC021) or Position Buffer Read
(Bit 15 of OWC021) is ON.
In this case, the setting range is 1 ~ 256. It
is disabled if 0 is set.
Used when a motion command
(OWC020) is used in the position control
mode. 0
