8.4.1 Operation
This section describes the cam operation.
(1) Procedure for switching from the real mode to virtual mode
Set the devices by the following procedure using the Motion SFC program at the
switching from real mode to virtual mode.
(a) Set the following details.
• Set the cam No. and stroke amount in the "cam No. setting device" and
"stroke amount setting device" set in each cam shaft parameters.
• Turn the cam reference position setting command (M3214+20n) on/off as
required.
(Refer to Section 4.1.2 (4))
(b) Execute the real mode/virtual mode switching request.
(M2043: OFF ON)
(c) Start operation based on the cam pattern, stroke amount and cam reference
setting command set in each cam shaft.
(2) Processing at the switching from the real mode to virtual mode
The current value within 1 cam shaft revolution is indexed based on the cam
reference position setting command (M3214+20n), feed current value, lower
stroke limit value, stroke amount and cam No. (cam pattern) at the switching from
real mode to virtual mode.
(3) Operation
A value calculated by the stroke ratio of cam data table based on the current
value within 1 cam shaft revolution is output.
[Feed current value] = [Lower stroke limit value] + [Stroke amount] [Stroke ratio]
The current value within 1 cam shaft revolution is set by the travel value that the
travel value of drive module multiplied by a gear ratio of transmission module.
Number of pulses per stroke amount is controlled based on the travel value per
pulse set in the fixed parameter in the real mode.
(4) Switching the stroke amount and cam No. during operation
(a) The cam stroke amount and execute cam No. can be changed using the
Motion SFC program during cam operation.
(b) The stroke amount and cam No. are changed by the address set in the
"stroke amount, cam No. change point" at the creating cam data.
When the "stroke amount, cam No. change point" is passed, the stroke
amount/cam No. is changed based on the value of the stroke amount setting
device and cam No. setting device set in the cam parameters.
