7.3 PO-01 Parameters
7-45
7
34 Motion Com-
mand Control
Flags
(MCMDCTRL)
(cont’d) Bits 4 to 7 Filter Type
Selection
(FILTER-
TYPE) Set the type of acceleration filter.
0: No filter
1: Exponential filter
2: Average movement filter
OW††14: Filter Time Constant is valid if this
parameter is set to “1” or “2.” 0
(No filter)
Bits 8 to
11 Not used. Set to “0.” 0
Bit 12 Reverse Limit
Signal for
Zero Point
Return
(LMT_L) This bit functions as a reverse limit signal when
returning to the zero point (ZRET).
The external signal (DI signal input by the LIO-01 or
other Module) in the user program must be con-
nected (i.e., programmed) to OB††21C.
0: OFF, 1: ON 0
Bit 13 Forward Limit
Signal for
Zero Point
Return
(LMT_R) This bit functions as a forward limit signal when
returning to the zero point (ZRET). The external sig-
nal (DI signal input by the LIO-01 or other Module)
in the user program must be connected (i.e., pro-
grammed) to OB††21D.
0: OFF, 1: ON 0
Bit 14 Position
Buffer Write
(BUF_W) Data set in OL††3A: Position Buffer Write Data is
stored as absolute position data in the position buffer
that is set at OL††38: Position Buffer Access
Number.
0: OFF, 1: ON 0
Bit 15 Position
Buffer Read
(BUF_R) Data from the position buffer that is specified at
OL††38: Position Buffer Access Number is stored
as absolute position data in the position buffer that is
set at IL††28: Position Buffer Read Data. This
parameter is used to check position data that is stored
in the position buffer.
It takes two scans from the time the Position Buffer
Read command is issued until the data is stored at
IL††28: Position Buffer Read Data.
0: OFF, 1: ON 0
35 Rapid Traverse
Speed (RV) OL††22
0 to 2 31 -1 Set the rapid traverse speed in 10 n reference units/
min (n: Number of digits below decimal point) if
OB††01D: Speed Reference Selection is set to
“0.”
Other setting units are expressed as follows:
Pulse unit: 1 = 100 pulses/min
mm unit: 1 = 1 mm/min
deg unit: 1 = 1 deg/min
Inch unit: 1 = 1 inch/min
This parameter is used when an OW††20: Motion
Command Code is used in Position Control Mode.
0
37 Not used. OW††24 − Set to “0.” 0
39 Stopping
Distance
(STOPDIST) OL††26
-2 31 to 2 31 -1
This parameter is used by the system. Do not use it. 0
