adaptors(PWM): fix wrong duty cycle after kill program

[gen2thomas]

Solved issues and/or description of the change

After a program with PWM usage is stopped by e.g. STRG-C, a restart is sometimes not possible due to bad state of duty cycle value. This can be solved by automatically adjusting the duty cycle on program start. This feature still exist, but was not enabled before.
