P0021 – Value of Frequency Input FI in %
Adjustable
Range:
-100.0 to 100.0 %
Factory
Setting:
Properties: ro
Access groups
via HMI:
READ, I/O
Description:
This read-only parameter indicates the value of the frequency input in percentage of full scale. The indicated
values are those obtained after the offset action and multiplication by the gain. Check the description of
parameters P0247 to P0250.
P0022 – Value of Frequency Input FI in Hz
Adjustable
Range:
0 to 20000 Hz
Factory
Setting:
Properties: ro
Access groups
via HMI:
READ, I/O
Description:
Value in hertz of the frequency input FI.
NOTE!
The operation of parameters P0021 and P0022, as well as of the frequency input, depends on the
activation of P0246.
P0246 – Frequency Input FI
Adjustable
Range:
0 = Inactive
1 = Active Factory
Setting:
0
Properties:
Access groups
via HMI:
I/O
Description:
When in "1" this parameter activates the frequency input, making the digital input DI2 function in P0264 be
ignored, as well as the value of bit "1" of P0012 is maintained in "0". On the other hand, when in "0" the
frequency input is inactive keeping parameters P0021 and P022 in zero.
