8402 BDO DST BLK NBL
[Data type] Bit
BDO, NBL Set the type of acceleration/deceleration before interpolation.
BDO NBL Meaning
0 0 Acceleration/deceleration prior to interpolation is of lin-
ear type
1 1 Acceleration/deceleration prior to interpolation is of bell
shape type
BLK Be sure to set to 0.
DST Be sure to set to 1.

#0
[Data type] Bit
MSU When G00, or an M, S, T, or B code is specified in HPCC mode:
0 : An alarm is issued.
1 : The CNC executes the command.
SG0 When G00 is specified in HPCC mode:
0 : The setting of bit 1 (MSU) of parameter No.8403 is followed.
1 : The tool is moved along the axis at the feedrate set with parameter
No.8481, replacing the G00 command with the G01 command,
regardless of the setting made for bit 1 (MSU) of parameter No.8403.

STG
[Data type] Bit
STG The positioning command (G00) is processed as follows on the RISC
side:
0 : The tool is moved along the axis at the feedrate set with parameter
No.8481, replacing the G00 command with the G01 command.
1 : The G00 command is executed as is.
CAUTION
The STG parameter is valid when the SG0 parameter (bit 7
of parameter No.8403) is set to 1.
HG0 This paraemter must be set to 1 in case that positioning command (G00) is
executed with the RISC board in the same way as normal G00
(parameter No.8403#7=1,No.8404#0=1).
