6 SVB Module Specifications and Handling
6.2.2 Motion Setting Parameters
6-34
46 Position Con-
trol Flags
(POSCTRL) OW††2D Set the functions related to position data managed by SVB Modules. The bit configuration
is described below.
Bit 0 Machine Lock
Mode Setting
(MLK) The axis does not actually move, but rather IL††02:
Calculated Position in Machine Coordinate System is
refreshed in Machine Lock Mode.
This parameter is valid when IB††152: Distribution
Completed is ON if the bit is changed. 0
Bit 1 Request for the
Preset Number
of POSMAX
Turns
(TPRSREQ) Request for the preset number of POSMAX turns.
•With an infinite length axis, a turn is counted every time
the position value exceeds POSMAX and the count is
stored at monitoring parameter IL††1E: Number of
POSMAX Turns.
• The number of turns can be preset at setting parameter
OL††30: Preset Data for Number of POSMAX Turns
by turning ON the Request for the Preset Number of
POSMAX Turns Flag.
Related Parameters:
• Fixed parameter No. 23:
Infinite Length Axis Reset Position (POSMAX)
• Setting parameter OL††30:
Preset Data for the Number of POSMAX Turns
• Monitoring parameter IL††1E:
Number of POSMAX Turns
0
Bit 2 ABS System
Infinite Length
Position Control
Data Load
Request
(ABSLDREQ) If this bit is ON when using an infinite length axis with an
absolute encoder, position data controlled by the SVB
Modules will be refreshed with data that is set at
OL††38 and OL††3A: Encoder Position at Shutdown
and at OL††3C and OL††3E: Pulse Position at Shut-
down.
Conditions
Fixed parameter No. 3: Encoder Selection 1
Fixed parameter No. 17: bit 5=1, Infinite Length Axis 0
Bits 3 to 11 Not used. Set to “0.” 0
