Information/possible settings
nCInhVal_a
INT
Main setpoint signal which is to be accepted by the main setpoint integrator when
the controller is inhibited.
bRfgStop
BOOL
Holding (freezing) of the current value of the main setpoint integrator
TRUE The current value of the main setpoint integrator is held.
bRfg0
BOOL
Leading the main setpoint integrator to 0 within the current Ti times
TRUE The current value of the main setpoint integrator is led to "0" within
the Ti time set.
bNSetInv
BOOL
Signal inversion for the main setpoint
TRUE Main setpoint signal is inverted.
nNset_a
INT
Main setpoint signal
• Other signals are also permitted
bJog1 ... bJog8
BOOL
Selection inputs for fixed changeover setpoints (JOG setpoints) for the main setpoint
• Selection inputs are binary coded.
bTI1 ... bTI8
BOOL
Selection inputs for alternative acceleration/deceleration times for the main
setpoint
• Selection inputs are binary coded.
nSet_a
INT
Starting value which is loaded into the main setpoint integrator by setting bLoad to
TRUE.
bLoad
BOOL
Control of both ramp function generators in special situations, e.g. QSP
TRUE The nSet_a input signal is loaded into the main setpoint integrator
and the additional setpoint integrator is set to "0".
bAddInv
BOOL
Signal inversion for the additional setpoint
TRUE Additional setpoint signal is inverted.
nNAdd_a
INT
Additional setpoint signal
• Other signals are also permitted
bExternalCINH
BOOL
Additional load input for the main setpoint integrator and the additional setpoint
integrator
TRUE The main setpoint integrator is set to the value applied at
nCInhVal_a.
The additional setpoint integrator is set to "0".
