7.3.2 Parameter Settings For Analog Velocity Control Mode
M2 series AC servo drive has 2 12bits analog AD converters. When single ended input signal is used,
analog input 1 (ANA1) is used for velocity command, analog input 2 (ANA2) is used for rotating toque
command. Differential input via ANA1/ANA2 is also available. In addition, low pass filter, offset and
deadband can also be set to the drive.
