sub−control panel, check the cam shaft turns in the normal direction and stops roughly after 1
revolution.
=CHECK=
x If the cam shaft turns in reverse, check Cn−02 bit of the motor driver to set to “0“.
x If the cam shaft does not turn at all, check the motor driver alarm display.
x Check the cam shaft’s relation with the X−Y table while turning.
(4) Working from the sub−control panel, check shifting across all 4 speeds.
7.2.3 Manual Mode Movement Check
(1) Set the machine to the manual mode. While turning the hand wheel to move the cam shaft, check
