3.2.20.1 Profile setpoint position and second machine setpoint
At CCTRL2−IN, the profile setpoint position is specified. The machine setpoint position is output at
CCTRL2−PHI−SET. It is the reference value for controlling the cam.
For auxiliary function like inching mode, position override setpoint (e.g. approaching the cleaning
position) or homing, you can define a second machine setpoint position at CCTRL2−PHI−SET2. If a
changeover to the second machine setpoint position is effected, the machine setpoint position at
CCTRL2−PHI−SET is maintained and can be approached again after the auxiliary function has been
completed.
Activating profile setpoint position at CCTRL2−IN

Stop!
Destruction of the machine!
If the outputs CCTRL2−PHI−SET2 and CCTRL2−PHI−SET output different values
when the profile setpoint position is activated (CCTRL2−N2−SET = LOW), this will
result in uncontrolled machine movements due to following errors.
Protective measures:
Set the outputs CCTRL2−PHI−SET2 and CCTRL2−PHI−SET to the same values
before activating the profile setpoint position. You have two possibilities:
l Direct the value at CCTRL2−PHI−SET2 to the value at CCTRL2−PHI−SET via the
input signal at CCTRL2−NSET2.
l Set CCTRL2−RESET = HIGH. By this, CCTRL2−PHI−SET is set
= CCTRL2−PHI−ACT.
l Set the outputs CCTRL−PHI−SET2 and CCTRL−PHI−SET to the same values.
l Set CCTRL2−N2−SET = LOW.
l The integrator for the second machine setpoint is reset. CCTRL2−PHI−SET2 is set
= CCTRL2−PHI−ACT, in order to be able to traverse from the current position when the second
machine setpoint is activated.
Activating the second machine setpoint at CCTRL2−NSET2
l Set CCTRL2−N2−SET = HIGH.
Resetting the machine setpoint
l Via CCTRL2−RESET = HIGH, CCTRL2−PHI−SET is set = CCTRL2−PHI−ACT.
