ABB ACS320 - Loop Gains; Point Database

316 Fieldbus control
 Loop gains
PRC PID GAIN (Point 50) and PRC PID ITIM (Point 51) are PID parameters similar to
the P and I gains in the APOGEE TECs. Because the ABB PI loop and the Siemens
loop are structured differently, there is no a one-to-one correspondence between the
gains. The following formulas allow translation from ABB gains to Siemens gains and
vice versa:
• To convert from ABB PI gains to Siemens P and I gains:
• To convert from Siemens P and I gains to ABB PI gains:
