Its important to verify the axis status by confirming that the controller is ready, IB80000 (Axis 1)
and the ServoPack is ready, IB80003 (Axis 1). MB00101D (Axis 1.) Breakout the main power on
bit. IB802C4 (Axis 1). In the above code, "Axis Normal" is one of the conditions required to
enable the servo. An alarm, loss of ServoPack power, or communication error will disable the
axis. Also note that the user input is in series with a rising edge one shot to prevent rapid
toggling of the enable signal.
A normally open contact for breaking the latch of the servo on reference MB001001 (Axis 1) is
common practice for machine control from using hardwired normally closed stop push buttons.
