NSK MEGATORQUE M-ESA-Y3040T25 - Analog Velocity Command

— 10-21 —
10.3.2. Analog Velocity Command
l In the velocity control mode operation, the Motor may be controlled directly by inputting analog
command.
◊ Voltage range of analog command is ±10V. The offset adjustment may be performed
with VR1 pod on the front panel of a Driver Unit.
◊ Setting the parameter AC reverses the polarity of analog command voltage.
AC1 : Analog voltage + : CCW
AC -1: Analog voltage + : CW
◊ The parameter AGV changes the relation between analog voltage and velocity.
