3 Function Specifications
MITSUBISHI CNC
3-1-11 Spindle synchronous control
This control enables two spindles to run at the same speed. A spindle being driven with a speed command is
synchronized with another spindle at a constant rate or acceleration/deceleration rate.
This control is applied such as when a workpiece is transferred between two rotating chucks in lathe or a
workpiece is held with two chucks.
3-1-12 Spindle/C axis control
An axis rotating about Z axis is called C axis, whose rotation direction is normally the same as of spindle.
This function enables high-accuracy spindle control including interpolation control, like servo axis, when a
high-resolution position detector is attached to the spindle motor.
3-1-13 Proximity switch orientation control
Orientation control is carried out based on the leading edge position of the proximity switch output signal
(ON/OFF).
3-1-14 Power regeneration control
This control enables the regeneration energy generated when the motor decelerates to return to the power
supply.
This is an energy saving method because regeneration energy is hardly converted to heat.
3-1-15 Resistor regeneration control
This control enables the regeneration energy generated when the motor decelerates to convert to heat with
regenerative resistance.
The drive system can be downsized because the regeneration capacity is also small in the motor of relatively
small capacity.
Select a suitable regenerative resistance according to the load inertia, motor operation speed, etc.
