7.3.3 Motion Monitoring Parameters
7-52
24 Position Control
Status
(POSSTS) IW††17 This parameter indicates status related to position controlled by PO-01 Modules.
Bit 0 Machine Lock
ON (MLKL) Turns ON when machine lock is ON and pulses will not be output.
The axis that is being controlled will be locked and will remain
stopped.
Bit 1 Zero Point Posi-
tion (ZERO) Turns ON when zero point return (IB††156) has been completed
and when 0
≤ |IL††18: Reference Position in Machine Coordinate
System| ≤ OW††83: Zero Point Position Output Width.
Bit 2 Second In-posi-
tion Completed
(PSET2) Turns ON when Distribution Completed (bit 2 of IW††15) turns
ON.
Bit 3 Not used. −
Bit 4 Preset Request
for Number of
POSMAX Turns
Completed
(TPRSE) Turns ON when OB††2D1: Request for Preset Number of POS-
MAX Turns is ON and presetting has been completed. It turns OFF
when OB††2D1: Request for Preset Number of POSMAX Turns
goes OFF and is valid when infinite length axis is set.
Bit 5 Electronic Gear
Enabled Selec-
tion (GEARM) Indicates the electronic gear enabled selection at bit 4 of motion
fixed parameter number 17.
Bit 6 Axis Selection
(MODSELM) Indicates the axis selection at bit 5 of motion fixed parameter num-
ber 17.
Bits 7 to 15 Not used. −
25 Machine Coordi-
nate System
Reference
Position
(MPOS) IL††18
-2 31 to 2 31 -1
This parameter is the reference position in the machine coordinate
system and is basically the same value at IL††02 (CPOS).
This position data cannot be updated if IB††170: Machine Locked
is ON.
27 Not used. IL††1A − −
29 POSMAX
Monitor
(PMAXTURN) IL††1C
1 to 2 31 -1
Indicates the infinite length axis reset position
(POSMAX) at motion fixed parameter number 23.
31 Number of POS-
MAX Turns
(PMAXTURN) IL††1E
-2 31 to 2 31 -1
The count at this parameter goes up and down every time the reset
position (POSMAX) for the infinite length axis at motion fixed
parameter 23 is exceeded.
The parameter can be preset with OL††30: Preset Number of POS-
MAX Turns and with OB††2D1: Request for Preset Number of
POSMAX Turns.
33 Not used. IL††20 − −
