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
