Types and roles of control data
Operation of the positioning system is achieved through the execution of necessary controls. (Data required for
controls are given through the default values when the power is switched ON, which can be modified as required by
the program.)
Controls are performed over system data or machine operation.
• Controlling the system data: Performs write/initialization, etc. of the LD75 "setting data". (the system control
data [Cd.1], [Cd.2])
• Controlling the operation: Setting operation parameters, changing speed during operation, interrupting or
restarting operation (the system control data [Cd.41] and [Cd.42], and the axis control data [Cd.3] to [Cd.40])
(1) Controlling the system data
(a) Setting and resetting the setting data
(2) Controlling the operation
(a) Controlling the operation
(b) Controlling operation per step
