Duty cycle n: 1~65535
Output pulse f: 1~100KHz
XD series PLC PWM output need transistor type terminal:
XD2-16T/RT -24T/RT -32T/RT -48T/RT -60T/RT
XD3-16T/RT -24T/RT -32T/RT -48T/RT -60T/RT
XD5-16T -24T/RT -32T/RT -48T/RT -60T/RT
XD5-24T4 -32T4 -48T6 -60T6
XDM-24T4 -32T4 -60T4 -60T10
XDC-24T -32T -48T -60T
XD5E-30T4 -60T10
XDME-60T10
XL3-16T
XL5-32T4、XL5E-32T4、XLME-32T4
Duty cycle of PWM output =n /65535× 100%
PWM use the unit of 0.1Hz, so when set S2 frequency, the set value is 10 times of the actual
frequency (10f). E.g.: to set the frequency as 72 KHz, and then set value in S2 is 720000.
When X0 is ON, output PWM wave; When X0 is OFF, stop output. PMW output doesn't
have pulse accumulation.
