MITSUBISHI CNC
3-5 Sequence functions
3-5-1 Contactor control function
With this function, the contactor ON/OFF command is output from the power supply unit (or servo/spindle
drive unit for integrated type) based on the judgement as to whether it is in emergency stop, emergency stop
cancel, spindle deceleration and stop or vertical axis drop prevention control, etc.
3-5-2 Motor brake control function
With this function, the brake ON/OFF command is output from the servo drive unit based on the judgement
as to whether it is in emergency stop, emergency stop cancel or vertical axis drop prevention/pull-up control,
etc.
When a multiaxis drive unit is connected, all the axes are simultaneously controlled.
3-5-3 External emergency stop function
Besides the emergency stop input from the NC, double-protection when an emergency stop occurs can be
provided by directly inputting an external emergency stop, which is a second emergency stop input, to the
power supply unit (servo/spindle drive unit for integrated type).
Even if the emergency stop is not input from NC for some reason, the contactors will be activated by the
external emergency stop input, and the power can be shut off.
