5.1.5 Control terminals
P410 Min. freq. a-in 1/2 P
Setting range
-400.0 ... 400.0 Hz
Factory setting
{ 0.0 }
Description
"
Minimum frequency auxiliary setpoints
". The minimum frequency that can act on the
setpoint via the auxiliary setpoints. Auxiliary setpoints are all frequencies that are
additionally delivered for further functions in the FI:
• Actual frequency PID
• Frequency addition
• Frequency subtraction
• Auxiliary setpoints via BUS
• Process controller
P411 Max. freq. a-in 1/2 P
Setting range
-400.0 ... 400.0 Hz
Factory setting
{ 50.0 }
Description
"Maximum frequency auxiliary setpoints". The maximum frequency that can act on the
setpoint via the auxiliary setpoints. Auxiliary setpoints are all frequencies that are
additionally delivered for further functions in the FI:
• Actual frequency PID
• Frequency addition
• Frequency subtraction
• Auxiliary setpoints via BUS
• Process controller
P412 Nom.val process ctrl S P
Setting range
-100 ... 100 %
Factory setting
{ 5 }
Description
"
Process controller setpoint
". Fixed specification of a setpoint for the process
controller that will only be occasionally altered.
P413 PID control P comp. S P
Setting range
0.0 ... 400.0 %
Factory setting
{ 10.0 }
Description
This parameter is only effective if the function „”PID actual frequency” is selected.
The P-component of the PID controller determines the frequency jump if there is a
control deviation based on the control difference.
E.g.: At a setting of P413 = 10 % and a controller deviation of 50 %, 5 % is added to
the actual setpoint.
P414 PID control I comp. S P
Setting range
0.0 ... 3000.0 % / s
Factory setting
{ 10.0 }
Description
This parameter is only effective when the function “PID actual frequency” is selected.
The I-component of the PID controller determines the frequency change depending on time.
