§ Cd37 Frequency gain setting (Settable range 20~200)
Select ratio of frequency gain
Gain setting for external input signals are available using this function.
Output Frequency = Set Value × Frequency Gain × MAX. Frequency
Ex. Under the mode of external voltage (0-10V) frequency setting, frequency gain =
100%, set voltage to 2V,MAX. Frequency (FH) is 120Hz:
Output Frequency = (2V/10V) × 120Hz × 100% = 24Hz
If change frequency gain to 150%, then
Output Frequency = (2V/10V) × 120Hz × 150% = 36Hz

Note: If the maximum frequency (FH) exceeds more than 120Hz, gain setting of larger
than 100% is ignored and fixed at 100% and input data of Cd37 will not be
changed.
§ Cd38 Analog output calibration (Settable range 90~110)
Set the ratio of frequency graduation calibration then
Cd38=99: 99% of initial factory
Cd38=101: 101% of initial factory
Set Cd54 to select analog output
