The stepper drive specifications dictate the choice of the maximum PFM clock frequency, and pulse
width.
width.
Step 1: Choose Max PFM clock by changing the PFM clock divider. Click on calculate to see results.
Step 2: Choose PFM Pulse width by changing I7m04. Click on calculate to see results.
The output frequency control Ixx69 specifies the maximum command output value which corresponds to
the maximum PFM Frequency.
Example: Channels 5-8 are driving 4 stepper drives-motors, and require a PFM clock range of 0-20 KHz
and a pulse width of ~20 μsec.
PFM Clock Settings Example

The following example assumes that there is no encoder attached to
the motor, and the feedback is internally generated.
