Application Guide
Use this parameter to enable the feedback supervision function. Use the feedback supervision to make sure that the PID feedback
value stays in the set limits.

D Reference
11.15.6.2 (ID 736) Upper Limit
Location in the menu: P3.13.6.2
Use this parameter to set the high limit for the PID feedback signal. If the value of the PID feedback signal goes above this limit for
longer than the set time, a feedback supervision fault occurs.
11.15.6.3 (ID 758) Lower Limit
Location in the menu: P3.13.6.3
Use this parameter to set the low limit for the PID feedback signal. If the value of the PID feedback signal goes below this limit for
longer than the set time, a feedback supervision fault occurs.
Set the upper limit and the lower limit around the reference. When the actual value is less or more than the limits, a counter starts to
count up. When the actual value is between the limits, the counter counts down. When the counter gets a value that is higher than
the value of P3.13.6.4 Delay, an alarm, or a fault shows. It is possible to select the response with parameter P3.13.6.5 (Response to
PID1 Supervision Fault).
11.15.6.4 (ID 737) Delay
Location in the menu: P3.13.6.4
Use this parameter to set the maximum time for the PID feedback signal to stay outside the supervision limits before the feedback
supervision fault occurs. If the target value is not reached in this time, a fault or alarm shows.
