In the Devices tree, double-click MyController > Embedded Functions > PTO_PWM.

2

Select a PTO 0 tab.

3

In the PTO / PWM > PTO00 > Mode drop-down menu, select PWM.

Result: The PTO 0 tab Variable becomes PWM00 and the PTO 1 tab Variable becomes PWM01.

Enable the PWM channel: Set the Mode parameter to PWM.

Result: EcoStruxure Machine Expert creates a variable named PWM00 or PWM01 depending on the selected channel.

NOTE: You can rename the variable by entering a new name in the Variable field. When creating a PWM function block, you can find the Global Variable name representing the channel from the Input Assistant when naming the block.

2

In the list box of EN parameter, enable/disable the IN_EN physical input.

3

Configure the filter value of the IN_EN input (if enabled in step 2).

4

In the list box of SYNC parameter, enable/disable the IN_SYNC physical input.

5

Configure the filter value of the IN_SYNC input (if enabled in step 4).

Configure the filter value of the SYNC input (if enabled in step 4).

6

Configure the edge (rising or falling) for IN_SYNC signal detection (if enabled in step 4).
