Legend
(1): in the case of a program where the second comand comes before the first command, you have to add one PLC period task on the equation.
c: PLC period task
TcMH: Lexium 15 MP/HP cycle time (0 to 3 ms)
TcLP: Lexium 15 LP cycle time (0 to 1 ms)
TcATV31: ATV31 cycle time (15 ms)
TcATV71: ATV71 cycle time (5 ms)
Examples
Applications with 3 axis (Lexium 05):
c = 5 ms
Time start a MC_MOVEABSOLUTE with no changes = 1c = 5ms
Interruption delay of the same instance of MC_MOVEABSOLUTE = 1c+0,5ms = 5+0,5 = 5,5ms
Applications with 1 axis (Lexium 15LP):
c = 5 ms
Time start a MC_MOVEABSOLUTE with changes = 6c +1c = 6x5+5 = 35ms
