Ali, By default, do you mean you are using the configuration files in /config/m5i20, or something else? One of the things you have to do with the m5i20 board is to enable the PWM. That is found in the m5i20 configuration in the m5i20_io.hal file, here:
# Connect amp enables to m5i20 dac enables linksp Xenable => m5i20.0.dac-00-enable linksp Yenable => m5i20.0.dac-01-enable linksp Zenable => m5i20.0.dac-02-enable The enables are in turn set in core_servo.hal here: # connect the signals to the motion controller linksp Xenable <= axis.0.amp-enable-out linksp Yenable <= axis.1.amp-enable-out linksp Zenable <= axis.2.amp-enable-out If you are not getting TRUE on the amp-enable-out, then you will not be able to enable the m5i20 DACs (you can check this with halcmd show pin). For the time being, you could comment out the above lines and then add: sets Xenable TRUE sets Yenable TRUE sets Zenable TRUE Also it looks to me (someone more familiar with using this board for servo control might correct me) as though 1.0 is the maximum you will see on halscope, because the OUTPUT_SCALE is set to 1.0. Thus 0.0 => 0% duty cycle, and 1.0 => 100% duty cycle.
