6-51 Terminal 42 Output Min Scale
Range: Function:
0.00 %* [0.00 - 200.00 %]
6-52 Terminal 42 Output Max Scale
Range: Function:
100.00 %* [0.00 - 200.00 %]
EXAMPLE 1:
Variable value= OUTPUT FREQUENCY, range = 0–100 Hz
Range needed for output = 0–50 Hz
Output signal 0 or 4 mA is needed at 0 Hz (0% of range) - set par. 6-51
Terminal 42 Output Min Scale
to 0%
Output signal 20 mA is needed at 50 Hz (50% of range) - set par. 6-52
Terminal 42 Output Max Scale
to 50%
EXAMPLE 2:
Variable= FEEDBACK, range= -200% to +200%
Range needed for output= 0–100%
Output signal 0 or 4 mA is needed at 0% (50% of range) - set par. 6-51
Terminal 42 Output Min Scale
to 50%
Output signal 20 mA is needed at 100% (75% of range) - set par. 6-52
Terminal 42 Output Max Scale
to 75%
