7.2.3 PWM Output Function
For the pulse-width modulation output function there are two designated channels and
outputs.
NOTE
The PWM output function is only available with the transistor output type.
Output numbers
Channel no. Pulse output
0 Y0
2 Y3
Performance
Resolution Duty ratio (for pulse duration and period)
1000 1.5Hz–12.5kHz (0.0–99.9%)
100 15.6kHz–41.7kHz (0–99%)
Control flags
The PWM output status is stored in special internal relays. To access special data registers
and special internal relays, use the PLC-independent system variables. You can insert system
variables directly into the POU body: Use the "Variables" dialog without entering a declaration
in the POU header. See "
PWM Output Function" on page 151.
