I1 (Filter time constant for NV input): Effective for eliminating noise in the frequency
setting circuit. Increase the filter time constant if steady operation cannot be
performed due to noise. A higher setting results in slower response (t gets longer).
t36 to t39: Setting input range and corresponding frequency to -10V to 0V V1 input
voltage
Ex) when minimum (-) input voltage is -2V with corresponding frequency 10Hz and
Max voltage is –8V with run freq. 50Hz.
t40 to t44: Setting input range and corresponding frequency to 0 to +10V V1 input
voltage
Ex) when minimum (+) input voltage is 2V with corresponding frequency 10Hz and
Max voltage is 8V with run freq.
