8 OUTPUT MODULE
(11) Cam/ball screw switching command device
(a) This parameter is used to set cam operation.
(b) The following devices can be used as the cam/ball screw switching
command device.
Name Setting range
Input
X0 to X1FFF
(Note-1)
Output Y0 to Y1FFF
Internal relay
M0 to M8191
(Note-2), (Note-3)
Link relay B0 to B1FFF
Annunciator F0 to F2047
Multiple CPU area device
U
\G10000.0 to U \G(10000+p-1).F
(Note-4)
(Note-1): The range of "PXn+4 to PXn+F" cannot be used (fixed at 0) for the input
device (PXn+0 to PXn+F) allocated to the built-in interface in Motion CPU
(DI). (n: First input No.)
QDS
(Note-2): "M4000 to M4639 and M4800 to M5439" are the dedicated devices of
virtual servomotor axis in the virtual mode.
Unused area of virtual servomotor axis can be used as a user side.
(Note-3): Use these parameters to use the device (M5488 to M5519) allocated to
Q17
CPUN/Q17 HCPU.
(Note-4): "p" indicates the user setting area points of the Multiple CPU high speed
transmission area for each CPU.
(c) The following operation is executed depending on the setting unit by turning
the cam/ball screw switching command on corresponding to each output
axis No.
mm : Same operation as ball screw.
inch : Same operation as ball screw.
degree : Same operation as rotary table.
QDS
PLS : Same operation as ball screw.
(d) Operation of output axis by cam/ball screw switching command is shown
below.
Items Operation details

command : OFF
Specified cam pattern operation
• Unit: mm, inch, PLS
Same operation as ball screw.
• Unit: degree
QDS
Same operation as rotary table.
Command to servo amplifier = Preset command to servo amplifier +
Drive module travel value[PLS]
Gear ratio
Cam/ball screw switching
command : ON
(Note): Feed current value is calculated based on the travel value per pulse set
in the fixed parameter.
