Application Guide
Use this parameter to invert the error value of the PID controller.
10.99 (ID 341) PID Reference Rise Time
Location in the menu:
• P2.2.33 (PID Control Application)
• P2.2.1.6 (Pump and Fan Control Application)
Use this parameter to set the time during which the PID controller reference rises from 0% to 100%.
10.100 (ID 342) PID Reference Fall Time
Location in the menu:
• P2.2.34 (PID Control Application)
• P2.2.1.7 (Pump and Fan Control Application)
Use this parameter to set the time during which the PID controller reference falls from 100% to 0%.
10.101 (ID 343) I/O Reference Selection
Location in the menu:
• P2.2.5 (PID Control Application)
•
P2.2.1.1 (Pump and Fan Control Application)
Use this parameter to select the frequency reference source when I/O terminal is the control place and the reference source B is
active.
Selection number Selection name
0 AI1 reference
1 AI2 reference
2 AI3 reference
3 AI4 reference
4 Keypad reference (parameter R3.2)
5 Reference from Fieldbus (FBSpeedReference)
6 Motor potentiometer reference
7 PID controller reference
Select actual value (parameter ID 333 to ID 339) and the PID control reference (parameter ID 332). If value 6 is selected for this param-
eter in PID Control Application, the values of parameters ID 319 and ID 301 are automatically set to 13.
In Pump and Fan Control Application, the functions Motor potentiometer DOWN and Motorpotentiometer UP must be connected
to digital inputs (parameters ID 417 and ID 418), if value 6 is selected for this parameter.
10.102 (ID 344) Reference Scaling Minimum Value, Place B
Location in the menu:
•
P2.2.35 (PID Control Application)
•
P2.2.1.18 (Pump and Fan Control Application)
Use this parameter to set the minimum scaling point of the reference value.
10.103 (ID 345) Reference Scaling Maximum Value
Location in the menu:
• P2.2.36 (PID Control Application)
• P2.2.1.19 (Pump and Fan Control Application)
Use this parameter to set the maximum scaling point of the reference value.
