The process controller provides different internal status signals. These status signals can
be
assigned to the relay, the digital outputs or the NetWordOUT1 status word. For details
see chapter "Configuration of digital outputs".

Mappable parameter for the feedback of the variable (actual value) via
network.

Inhibited
Process controller deactivated.
1
Normal operation
The setpoint is higher than the fed back variable (actual value). If the
system deviation increases, the motor speed is increased.
Example: pressure-controlled booster pumps (increase in the motor
speed produces an increase in pressure.)
2 Reverse operation The setpoint is lower than the fed back variable (actual value). If the
system deviation increases, the motor speed is increased.
Example: temperature-
controlled cooling water pump (increase in motor
speed produces decrease in temperature.)
3
Normal bi-drectional
The direction of rotation corresponds to the sign of the system
deviation. If the system deviation increases, the motor speed is
increased.
4
Reverse bi-directional
A negative system deviation causes a positive direction of rotation. If
the system deviation increases, the motor speed is increased.

0 ... [100] ... 100 %
Setting of the maximum output frequency up to which the process
controller carries out regulation.

100 % ≡ Maximum frequency 0x2916 (P211.00).

Process controller setup (PID): Speed feedforward
control source
(PID setup: PID line speed)
Optional selection of a speed feedforward control source for the
process controller.
Is advisable, for instance, for dancer position controls if the motor
speed must not fall below line speed (process controller output value
= line speed + controlled motor speed).
Standard applications usually do not require a speed feedforward
con
trol; therefore it is deactivated in the default setting.

100 % ≡ Maximum frequency 0x2916 (P211.00).
The limitation becomes effective after the line speed has been added.
The value set here also limits the I component of the PID controller
(Integrator-Anti-Windup).
