2.3 Cautions for Power Supply from Q61P-A1/A2 to Q64AD-GH
When using the Q61P-A1/A2 and Q64AD-GH in combination, it is required to use them
within the range in Table 2.1.
This requirement applies to the case where the Q64AD-GH satisfies any of the
following conditions.
The first six digits of serial number are "050914" or earlier.
The first five digits of "Product information" number are "05081" or earlier.
If it satisfies the above conditions but does not meet the ones outlined in Table 2.1,
carry out the following:
Replace the power supply module with the Q64P.
Mount the Q64AD-GH to another base unit.
Table 2.1 Conditions for Use of Q61P-A1/A2 and Q64AD-GH in Combination
Available power supply
No. of Q64AD-GH
modules
Conditions
Q61P-A1/A2 Q64P
Total current consumption of all modules on the same
base is 5.0A or less.
3 or less
Total current consumption of all modules on the same
base exceeds 5.0A.
Module other than the Q64AD-GH is not mounted on
the same base.
4
Module other than the Q64AD-GH is mounted on the
same base.
5 or more
—
If the modules are used outside the condition range given in Table 2.1, the "POWER" LED of
the power supply module may flicker and the PLC CPU system may not start.
REMARK
When the Q64AD-GH satisfies any of the following conditions, the above precaution
does not apply.
The first six digits of serial number are "051217" or later.
The first five digits of "Product information" number are "05082" or later.
