Application Macro PID Control
This macro is intended for use with different closed-loop control systems
such as pressure control, flow control, etc.
The value of parameter 9902 is 6.
Note!
* DI2 must be activated before giving start command to DI1 while changing to
PID control (PID).
** Constant speed is not considered while in PID control (PID).
Note! The parameter 2107
START INHIBIT should be 0 (OFF).
Critical frequencies (group 25) are ignored while in PID control (PID).
PID control parameters (group 40) do not belong to the Basic parameter set.
PID Control parameter values:
Input signals Output signals DIP switch S1
• Start/stop (DI1) • An. output AO: Frequency
• Analogue reference (AI1) • Relay output 1: Fault
• Actual value (AI2) • Relay output 2: Running
• Control location selection (DI2)
• Constant speeds (DI4,5)
