PA-13 PID feedback loss detection value

PA-14 PID feedback loss detection time 0.0s ～ 3600.0s 0s
☆
This function code is used to judge whether the PID feedback is lost.
When the PID feedback amount is less than the feedback loss detection value PA-13, and
the duration exceeds the PID feedback loss detection time PA-14, the inverter will perform
protection according to the one-digit selection of P9-24, and report ERR32 for faults and
ALA32 for alarms.

In some applications, a set of PID parameters cannot meet the needs of the entire operation
process, and different PID parameters need to be used in different situations. This group of
function codes is used for switching between two groups of PID parameters. Among them,
the setting method of the regulator parameters PA-18~PA-20 is similar to the parameters
PA-06~PA-08. PA-21 is the PID parameter switching condition:
PA-21=0: do not switch, use the first group of PID parameters.
PA-21=1: DI terminal switching, multi-function terminal function selection should be set to 43
(PID parameter switching terminal), when the terminal is invalid, select parameter group 1
(PA-06~PA-08), when the terminal is valid, select the parameter Group 2 (PA-18~PA-20).
PA-21=2 Automatically switch according to the deviation. When the absolute value of the
deviation between the reference and the feedback is less than the PID parameter switching
deviation 1 (PA-22), the PID parameter selects parameter group 1. When the absolute value
of deviation between reference and feedback is greater than PID switching deviation 2 (PA-
23), PID parameter selection selects parameter group 2. When the deviation between
reference and feedback is between switching deviation 1 and switching deviation 2, the PID
parameters are the linear interpolation values of two sets of PID parameters, as shown in
Figure 6-24.
