2 digital outputs with PWM functionality - EPM-S620
By integration of the GSE file VI010C19.gse you can specify all counter parameters via a hardware
configuration.
Read data: 4 bytes
Write data: 12 bytes
• PWMPD_I, PWMPD_II (pulse duration):
Determine the scanning ratio for the parameterised period by stating the duration for the HIGH
level for the corresponding PWM channel. The pulse duration should be chosen as factor for the
20.83 ns basis.
Value range: 48 ... 8388607 (1
s ... approx. 175ms)
• PWMPD_I, PWMPD_II (control word):
Here you can define the PWM output behaviour for the corresponding channel and start or stop
the PWM output.
