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.

Function
This parameter defines the min. allowable value of the PID reference.
The PID references are to be considered as percentage values. If 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
