The description of a unit having a 24–VDC power supply, indicating
that the unit must be turned on at the same time as the Power Mate i
or before the CNC power–on operation, has been modified as follows:
Turn on the unit at the same time as the Power Mate i. When the unit
is turned on at the same time as the Power Mate i, it is recommended
that connections be made on the power line of the same line.
Turning on the power at the same time:
If the following power–on timing is satisfied, the CNC and units are
regarded as being turned on at the same time:
CNC power supply
ON
Power supply of
units (including the
Power Mate)
t1
t2
ON
ON
ON
t1: 200 ms The units (including the other Power Mate as slave) are
turned on within
200 ms before the power to the Power Mate i is turned on.
t2: –500 ms The units (including the other Power Mate as slave) are
turned on within
500 ms after the power to the Power Mate i is turned on.
The description of a unit having a 24–VDC power supply, indicating that
the unit must be turned off at the same time as the Power Mate i or after
the CNC power–on, remains unchanged. (When power is turned off at the
same time, the power to the unit may be disconnected within 500 ms
before the power to the Power Mate i is turned off.)
