POINT
• Bias setting for 0 to 5VDC (0 to 10VDC) input: Use the calibration parameter
C2, C3 for setting.
• Gain setting for 0 to 5VDC (0 to 10VDC) input: Use Pr. 38, calibration
parameter C4 for setting.
• Bias setting for 4 to 20mADC input: Use calibration parameter C5, C6 for setting.
• Gain setting for 4 to 20mADC input: Use Pr. 39, calibration parameter C7 for
setting.
(For 4 to 20mADC input, set "4" in any of Pr. 60 to Pr. 63 (input terminal
function selection) and assign AU (current input selection) to any of terminals
RH, RM, RL and STR.
5.1 Changing the Output Frequency Setting of the
Frequency Setting Potentiometer
(Bias and gain of frequency setting voltage (current))
POINT
• Pr. 38, Pr. 39 and calibration parameters "C1 to C7" can be made to be read
by setting "1" (extended function parameter valid) in Pr. 30 "extended
function display selection".
The bias/gain of the frequency setting voltage (current) may be adjusted in any of
the following methods:
1) Changing the highest frequency
