Symbol explanation
Vin, Vout: Power supply
G: GND
N.C.: Not used
Note : The reading of the digital voltage tester is a quasi DC voltage measurement value.
Note that measurement values may vary if a voltage waveform that contains substantial AC components
is measured.
Measurement conditions :
Measurement should be performed under the conditions described below, unless otherwise specified:
Play style: Normal (The control unit and the drive unit are connected.)
Measurement mode : Idling (State when the AC power is set to ON)
