5.193 L_TbPIController - PI controller with limitation
This FB provides a simple PI controller with different control functions.
• The value output to the output dnOut is internally limited to the limit range parameterised in
C04095 and C04096 (default setting ±200 %).
• The bLimitActive output displays if a limitation is active.
• The function corresponds by approximation to the "PCTRL" function of the 9300 servo inverter.
