(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.

Internal relay
Link relay
Annunciator
Multiple CPU area device
(Note-1) : "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 an user side.
(Note-2) : Use these parameters to use the device (M5488 to M5519) allocated to
Q17 CPUN/Q17 HCPU.
(Note-3) : "p" indicates the user setting area points of the Multiple CPU high speed
transmission area for the each CPU.
(c) Cam executes the same operation as ball screw by turning the cam/ball
screw switching command on corresponding to each output axis No..
(d) Operation of output axis by cam/ball screw switching command is shown
below.
Items
Specified cam pattern operation
Same operation as ball screw
Command to servo amplifier = Preset command to servo amplifier +
(Note): Feed current value is calculated based on the travel value per pulse set
(e) The current value within 1 cam shaft revolution is calculated based on the
feed current value, lower stroke limit value, stroke amount and cam No.
(cam pattern) by turning off the cam/ball screw switching command.
It is invalid to turn on the cam/ball screw switching command to axis that
except cam axis.
If the cam/ball screw switching command is turned off outside the range of
"lower stroke limit value to stroke amount" for cam, a minor error (error
code: 5000) will occur.
