Parameter Settings
The frequency can be preset in a range of 1 … 20,000 Hz and the duty cycle in a
range of 0 … 100 %.
When switching on for the first time, the default values 250 Hz (for the frequency)
or 50 % (for the duty cycle) are loaded for these parameters.
4.5.3
Function of the Output Channels
Output 1 (DO 1): Output signal
Output 2 (DO 2): Direction output high / low (switchable via control byte)
Output 3 (DO 3): Output signal
Output 4 (DO 4): Direction output high / low (switchable via control byte)
4.5.4
Process Values
The number of PWM cycles to be generated is specified via the process output
data. 1 digit equals 1 PWM pulse.
Valid value range for the process image: 0 … 65535
