*1 Note that when the frequency setting is varied using an analog signal or of the operation panel (FR-DU07), the output of the SU (up to
frequency) signal may alternate on and off depending on that varying speed and the timing of the varying speed due to acceleration/
deceleration time setting. (The output will not alternate on and off when the acceleration/deceleration time setting is "0s".)
*2 When a power supply reset is performed, the alarm output 2 signal (ALM2) turns off as soon as the power supply switches off.
