3.2.6 Interpolation Acceleration Time Change (IAC) Command
! ! ! ! Outline
The Interpolation Acceleration Time Change (IAC) command sets up the acceleration
time for the execution of the interpolation feed commands (MVS, MCC/MCW, SKP).
! ! ! ! Detailed Explanation
The IAC command method is shown as follows:
The interpolation acceleration time designated by the IDC command equals the
amount of time required to reach the maximum interpolation feed speed designated by
the FMX command.
• When the IAC command is not executed, the acceleration time = 0 (rectangle).
• The acceleration time changed by the IAC command is valid until being reset by the
next IAC command.
• A designating range of the IAC commands is as indicated below
