3.11 I/O compound module − pulse width modulation
3.11.1 2 digital outputs with PWM functionality − EPM−S620
This module has two output channels with PWM functionality (PulseWidthModulation).
By specifying time parameters, you can forward a pulse train to the desired output with the
mark−to−space ratio you want.
Features
ƒ 2 PWM outputs, can be switched between "push/pull" and "highside"
– Push/pull mode should be used if you need defined high/low levels for a rapid
change. This is used with a low load especially if "highside" mode cannot move the
output to low fast enough during a low status. With push/pull, the output is
switched to ground with low active and to voltage with high active.
– In highside mode, the output switched to low remains in a state of uncertainty
between ground and voltage. The load has to "pull" itself to ground. In highside
mode, the switch is only made to high level active.
