PID low limit is the additional function code of Sinus M. H55 and H56 are related to each low
limit and high limit. When the drive runs, the output frequency should be reached to low limit
even if the feedback is higher than the reference. So, except during acceleration time from 0Hz
to low limit, the output frequency is between low limit and high limit at any time.

-
To stabilize the system (negative feedback system), the sensor output is high when the real
physical value is high. Sometimes, however, the sensor output is inverse, or the system needs
higher output when the signal is low. In that case, the inverse PID is used.
-
For this functionality, H59 code is used. PID output is increased when PID reference is higher
than feedback setting value “0”. PID output is decreased when PID reference is higher than
feedback setting value “1”.
-
When H59 is set to 1, the FBK display is the same. That is to say, the feedback is the same, but
the error is inverse.
-
This functionality affects Sleep and Wake Up operation. (Refer to Sleep & Wake up functionality
below).
