P244 Cycle Time of PID Regulator: Tc
P244
Range
5 ÷ 65000
0 ÷ 65000 ms
Default
5
5 ms
Level
ENGINEERING
Address
844
Function
This parameter sets the cycle time of PID regulator.
It is expressed in ms (multiples of 5 only).
Example: if P244
= 1000 ms, the PID regulator cycle will be executed every
second, and the output will be refreshed every second as well.
P245 Min. Value of PID Reference
P245
Range
–20000 ÷ +20000
±200.00%
Default
0
0.00%
Level
ENGINEERING
Address
845
Function
This parameter defines the min. allowable value of the PID reference.
The PID references are to be considered as percentage values. I
f analog
references are selected, P245 relates to the minimum
value of the selected
analog input.
Example: Select AIN1 analog input as the PID reference and suppose that its
max. and min. values are +10V and –10V respectively. If P245 is –
50%, this
means that the PID reference will be saturated at –
50% for voltage values lower
than –5V.
P246 Max. Value of PID Reference
P246
Range
–20000 ÷ +20000
±200.00%
Default
+10000
+100.00%
Level

Address
846
Function
This parameter defines the max. allowable value of the PID reference. See the
description of P245.
P247 Min. Value of PID Feedback
P247
Range
–20000 ÷ +20000
±200.00%

description of P245.
P248 Max. Value of PID Feedback
P248
Range
–20000 ÷ +20000
±200.00%
