7.3.1 Motion Fixed Parameters
7-34
17 Bit 9 Override Selection
(USE-OV) Set whether or not to use the override function.
(For interpolation related commands, set override in the
register specified in the Group Definition Window.)
0: Disabled
1: Enabled
The OW††2C: Override is used when this parameter is
set to Enabled. The override is fixed at 100 if this parame-
ter is disabled.
Note: The override function always the feed speed set-
ting to be modified in an application.
0
(Disabled)
Bit 10 Deceleration Limit
Switch Inversion
Selection
(INV_DEC) Set whether or not to invert and use the limit switch signal
(deceleration limit switch) when returning to the zero
point.
0: Not inverted
1: Invert 0
(Not inverted)
Bits 11 to 15 Not used. − −
18 Number of Digits
Below Decimal Point
(DECNUM) Set the number of digits to the right of the decimal point in input reference units.
The minimum reference unit is determined by this parameter and Reference Unit
Selection in the Motion Controller Function Selection Flags (bit 0 to bit 3). 3
