(b) Replacement using a connector/terminal block converter module
This replacement method is suitable when the Q Series large type base unit and conversion adapter
manufactured by Mitsubishi Electric Engineering Co., Ltd. cannot be used due to system configuration and
installation location restrictions.
Connect the input/output wires, which include solderless terminals, from the existing module to the
connector/terminal block converter module using a dedicated cable. This connection is not restricted by
differences in wiring size.
The following shows the wiring configuration when using a connector/terminal block converter module.
• The input filtering system and counting speed of replacement Q Series dedicated modules QD62-H01 and
QD62-H02 are the same as those of existing A (Large Type) high-speed counter modules AD61 and
AD61S1.
High-speed counter modules can be replaced without being restrained by the specifications of existing pulse
generators (e.g. an encoder).
• AD61/AD61S1 and QD62-H01/QD62-H02 have different counting ranges.
Modify the program in order to use the same counting range as that of the module before replacement.
• AD61, AD61S1:
0 to 16,777,215 (24-bit unsigned binary)
• QD62-H01, QD62-H02: -2,147,483,648 to 2,147,483,647 (32-bit signed binary)
• The number of points occupied by the module changes from 32 to16 points, and thus the I/O signal
assignment (X/Y) also changes. Due to additional functions, the buffer memory addresses are changed and
program modification is necessary. Check the specification at "High-Speed Counter Module User's Manual":
SH-080036, and modify the program.
