Feedf - Feedforward Power - gefran 650 Installation And Instruction Manual

4. CONFIGURATION

4.13.23. FEEDF - Feedforward power

Acronym
FEEDF FEEDFORWARD
The parameter shows and sets the feedforward power value, i.e., the value that generates an additional factor at the
control output based on the setpoint value.
Unit of measurement:
Options: -100.0...100.0
4.13.24. DEAD.B - Deadband
Acronym
DEAD.B DEAD BAND
The parameter shows and sets the deadband.
The deadband is symmetrical to the setpoint. If the process value (PV) stays in this band, the control output keeps the
required power value constant.
Unit of measurement:
Options: 0...999
4.13.25. FAULT - Fault action power
Acronym
FAULT FAULT ACTION POWER
The parameter shows and sets the fault action power, supplied if the sensor is broken.
Example
If Cntr = HP.CON (Proportional Heat, ON/OFF Cool), the option is On, OFF, 0.0...100.0, i.e., if you set FAULT = On the
cooling output will be ON in case of fault.
Unit of measurement:
Options: -100.0...100.0 for P or PI or PID action
On, OFF
4.13.26. GRAD.I - Setpoint gradient in increase
Acronym
GRAD.I SETPOINT GRADIENT IN INCREMENT
The parameter shows and sets the gradient used when the setpoint value is increased.
If the parameter is "0.0" the gradient is disabled.
Unit of measurement:
Options: 0.0...999.9
4.13.27. GRAD.D - Setpoint gradient in decrease
Acronym
GRAD.D SETPOINT GRADIENT IN DECREMENT
The parameter shows and sets the gradient used when the setpoint value is decreased.
If the parameter is "0.0" the gradient is disabled.
Unit of measurement:
Options: 0.0...999.9
90
