Figure 9-8: Output Frequency Supervision
2.3.12 Output frequency limit 1 supervision
function
ID315
0 No supervision
1 Low limit supervision
2 High limit supervision
If the output frequency goes under/over the set limit (par. 2.3.13) this function
generates a warning message via the relay outputs depending on the settings of
parameters 2.3.1 – 2.3.4.
2.3.13 Output frequency limit 1 supervised value ID316
Selects the frequency value supervised by parameter 2.3.12.
2.3.14 Analog input supervision ID356
With this parameter you can select the analog input to be supervised.
0 Not used
1 AI1
2 AI2
2.3.15 Analog input supervision OFF limit ID357
When the signal of analog input selected with par. 2.3.14 falls under the limit set with
this parameter, the relay output goes off.
2.3.16 Analog input supervision ON limit ID358
When the signal of analog input selected with par. 2.3.14 goes over the limit set with
this parameter, the relay output goes on.
This means that if for example ON limit is 60% and OFF limit is 40%, the relay goes
on when signal goes over 60% and remains on until it falls under 40%.
