2.3.32. Object 7452h: PID Integral Action Time
This object describes the integral time (Ti in Figure 14) of the PID algorithm. The physical unit is always
seconds, as defined in object 6458h, with the decimal digits (resolution) given in object 6459h. To prevent
instability, it is recommended to never set this less than three times higher than object 7454h (Td in Figure
14).

2.3.33. Object 7454h: PID Derivative Action Time
This object describes the derivative time (Td in Figure 14) of the PID algorithm. The physical unit is always
seconds, as defined in object 6458h, with the decimal digits (resolution) given in object 6459h. To prevent
instability, it is recommended to never set this more than three times smaller than object 7452h (Ti in Figure
14).
