DETAILS OF SIGNALS
().3. 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.
