It's not in the operator's manual, it's in the Parameter List
You need
P0003 set to 2 so that all the parameters you might want to change are accessible to you
P0700 set to 1 for command input to be BOB (panel)
You might need to select the control frequency setpoint source and a few other odds & sods but the Parameter List is where you'll find the settings described -
