t2:-500ms Means that the power to units (including the Power Mate)
is turned on within 500 ms after the power to the CNC is
turned on.
Turning the power to units off simultaneously when turning the power
to the CNC off:
This means that the power to units may be turned off within 500 ms
before the power to the CNC control unit is turned off. If the power
to units is turned off earlier, alarm information is left in the NC.

t1:500ms Means that the power to units are turned off within 500 ms
before the power to the CNC is turned off.
The power to the CNC must not be turned on or off with the power to
units on.
4.2.3 Power-on Sequence
Turn on the power to all the units at the same time, or in the following
sequence:
1 Power to the overall machine (200 VAC)
2 Servo amplifier control power supply (200 VAC)
3 Power to the slave I/O units connected via the I/O link, the separate
detector interface unit, and the stand-alone type LCD unit (24 VDC), power
to the CNC controller (24 VDC), power to the separate detector (scale)
As for a PANEL i, no specific power turn-on sequence for the CNC
control unit is required.
4.2.4 Power-off Sequence
Turn off the power to all the units at the same time, or in the following
sequence:
1 Power to the slave I/O units connected via the I/O link, the separate
detector interface unit, and the stand-alone type LCD unit (24 VDC), power
to the CNC controller (24 VDC)
2 Servo amplifier control power supply (200 VAC), power to the separate
detector (scale)
3 Power to the overall machine (200 VAC)
When turning off the power of the CNC controller, be sure to turn off
the power of units such as the slave I/O devices connected through I/O
Link, β amplifier with I/O Link, Power Mate and separate detector
