Setting of control input and output
Let’s set signals for “Detection for error in the Motor System,” “Start operation• Hold
operation” and “Automatic servo on after the power on”.
Change the initial settings of the output NRM (Normal), the input HLD (Hold operation), and
the input SVON (Servo on).
◊
The input SVON is not actually wired. However, its signal port has been set to the
normally closed polarity so that the Motor servo activates automatically when the
power is on.
