8 OUTPUT MODULE
(1) Number of pulses per cam shaft revolution (Nc)
(a) The number of pulses required to rotate the cam one cycle is displayed.
Number of pulses per cam
shaft revolution (Nc)
(b) The setting for the number of pulses per cam shaft revolution is not related
to the travel value per pulse (fixed parameter setting).
(2) Cam No. setting device (1 word)
(a) This device is used to set the device that sets in the Motion SFC program by
which the cam No. to control.
(b) The following devices can be set as the cam No. setting device.
Name Setting range
Data register D0 to D8191
(Note-1)
Link register W0 to W1FFF
Motion register #0 to #7999
Multiple CPU area device U \G10000 to U \G(10000+p-1)
(Note-2)
(Note-1) : D800 to D1559 are dedicated devices of virtual servomotor axis,
synchronous encoder axis and output module "Cam" in the virtual mode.
Unused areas of virtual servomotor axis and cam axis can be used as an
user device.
(Note-2) : "p" indicates the user setting area points of the Multiple CPU high speed
transmission area for the each CPU.
(c) When the cam No. setting device value is changed during operation, it
changes to the cam No. changed in the "stroke amount/cam No. switching
position" set at the cam creating.
(3) Permissible droop pulse value
(a) This device is used to set the permissible droop pulse value of deviation
counter.
(b) The deviation counter value is continually checked, and if it becomes larger
than the permissible droop pulse value, the error detection signal
(M2407+20n) turns on.
However, since the cam shaft operation continues, execute the error
processing by user side.
