10 BLOCK LINK EXAMPLES
10.5 PWM Output
■Multi function counter block detail window
*1 Cycle time = (Upper limit value - Lower limit value) × Clock cycle
*2 ON time = Cycle time - (Step No. 0 × Clock cycle)
*3 In the addition mode, the cycle time calculated from the following is applied.
Cycle time = (Upper limit value - Lower limit value) ÷ Addition value × Clock cycle
The items other than the above need not to be set.
