Pwm Safety Parameters - Siemens LME7 Series Basic Documentation

Parameter Meaning
559 PWM mode control
Determines the behavior of PWM control, delivering a PWM signal proportional to the preset output
(analog/3-position step input).
Control: Controls the PWM speed proportional to the output preset via the analog or 3-position step
input.
Safety mode: Control for defining the PWM safety parameters.
