AH500 Programming Manual 6-184 Device Function Setting range Description Device number number automatically set to 0, and is filled in with appropriate parameters Kc Kp, _ Ti K, Td K and Tf. _ i _ d PID MAN _ BOOL PID A/M mode True: Manual The MV is output according to the MOUT, but it is still within the range between the MV MIN and _ the MV MAX. When _ PID MODE is set to 1, the _ setting is ineffective. False: Automatic The MV is output according to the PID algorithm, and the output value is within the range between MV MIN and _ MV MAX. _ MOUT AUT _ O BOOL MOUT automatic change mode True: Automatic The MOUT varies with the MV. False: Normal The MOUT deos not vary with the MV.
CYCLE Double word/ DINT Sampling time (T ) S 1~40,000 (unit: ms) When the instruction is scanned, the PID algorithm is implmented according to the sampling time, and the MV is refreshed. (PLC will not use the setting value to determine the time or to operate automatically. ) If T is less than 1, it S will be counted as 1. If T is larger S than 40,000, it will be counted as 40,000. When the instruction PID is used in the interval interrupt task, the sampling time is the same as the interval between the timed interrupt tasks.
Kc Kp _ REAL Proportional gain (Kc or Kp) (The selection of Kc or Kp depends on the setting of the parameter PID EQ.) _ Range of positive single precision floating-point values It is a proportional gain. If a proportional gain is less than 0, Kc Kp _ will be count as 0. If Kc Kp is equal _
