4.2 TURNING ON AND OFF THE POWER TO THE CONTROL
UNIT
4.2.1 Power Supply for the Control Unit
Supply power (24VDC) to the control unit from an external sources.
Provide an ON/OFF circuit for turning the AC power on and off
outside the unit as shown in Fig. 4.2.1. To minimize the effect of
noise or voltage fluctuations to the CNC, it is recommended that a
power to the CNC be provided independently of the power sources to
devices with large noise or load fluctuations.
When the 30i series with PC functions is used, apply countermeasures
to guard against the possible destruction of hard disk storage due to
momentary power failure or power outage, by installing an
uninterruptible power supply, etc.
See Section 3.2 for power capacity.
