• Up 2 / Down 2 Command (75 vs. 76)
• Hold Accel/Decel Stop (A)
• Analog Frequency Reference Sample / Hold (1E)

Input Function Selection) not = 0 (Frequency Reference)
• b1-15 or b1-16 set to 3 but no option card connected
• Although b1-15 = 1 (Analog Input) and H3-02 or H3-10
are set to 0 (Frequency Bias).
