For direct action of the continuous controller, the controller action must be
changed ( ConF / Cntr / C. A ct = 1 ).
g
To prevent control outputs Out. 1 and Out. 2 of the continuous controller from
switching simultaneously, the control function of outputs Out. 1 and Out. 2 must
be switched off ( ConF / Out. 1 and Out. 2 / Y. 1 and Y. 2 = 0 ).
