... The L-Series PWM Input Looks Like... For This Type of PWM Source..

The document describes different types of PWM input sources that are compatible with the L-Series position controller. It shows that the L-Series can be configured for pull-down, pull-up, or push-pull PWM inputs. For each input type, it provides a circuit diagram showing how the signal would connect to pin 11 on the L-Series and be processed, either by comparing the clamped signal to a 2.5V reference or passing it directly to the processor.
