NC POWER ON

SERVO POWER ON

AND BRAKE RELEASE

OUTPUT

/NCMX: This output is turned on when the logic circuit of the control is energized.

(2) /SVMX: This output is turned on when the servo unit is energized. With an external servo

unit, turn on the power supply when this signal is output,

(3)

Output to release the retaining brake of the feed axis.

(4)

The power supply turning on sequence is as follows:

Close the power supply main switch for the control

Either depress the POWER ON button on the NC operator’s station, or close the circuit

between EON and

Then, the logic circuit and the servo control circuit are both

energized, and the output

signals (NC power input and output) is activated.
