5.6.7 W iring of System AC Power Supply
In order to avoid controller anomalies caused by voltage fluctuations, it is
recommended to provide sequential differences for the ON/OFF of the CNC power
and Servo power.
1. SERVO ON signal shall be activated in a slight delay after the activation of system
power supply, when the latter is stabilized.
2. Before switching off the system power supply, provide a delay for switching off the
SERVO ON signal first.
