Operation of the positioning control 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 sequence
program.)
Controls are performed over system data or machine operation.
• Controlling the operation :
Setting operation parameters, changing speed during operation, restarting operation
(through the axis control data Cd. 1 to Cd. 9 )
Refer to "Section 4.7 List of control data" for details of the control data.
Clear (reset) the axis error code ( Md. 5 ) and warning code ( Md. 6 ).
Change OPR request flag from "ON to OFF".
Set which control will be executed (start method).
Give a restart command during an axis operation stop.
Validate speed-position switching signal from external source.
Issue instruction to change speed in operation to Cd. 7 value.
(Made valid during speed control of speed-position switching control
or during JOG operation)
Set new speed when changing speed during operation.
Set the time taken at a speed change to reach the new speed from
the old speed.
Set the time taken at axis stop factor occurrence (axis stop signal ON
or error occurrence) to make a stop after reaching " Pr. 6 Bias speed
at start" from the speed after a speed change.
