4.1.7 Cam axis command signals
(1) Cam/ball screw switching command (M5488+n)
(a) This command is used when a cam is set as output module in the
mechanical system program.
Cam executes the same operation as a ball screw by turning ON the cam/
ball screw switching command corresponding to each output axis No..
• OFF ......... Specified cam pattern operation
• ON ........... Same operaion as ball screw
Therefore, it is invalid to turn ON the cam/ball screw switching command to
axis that except cam axis is set as output module.
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.
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 can be used in the SW6RN-SV22Q (Ver.00R or later).
(Command to servo amplifier [PLS] = Preset command to
servo amplifier + Drive module travel value [PLS]
Electronic gear ratio)
Feed current value is calculated based on the travel value
per pulse set in the fixed parameter.
