The program capacity of the CQM1 (7,200 words) is greater than that of the
CPM2C (4,096 words), and so the display will show more free space than is ac-
tually available. Be sure to keep the actual program capacity in mind while pro-
gramming.
When the program is transferred from the PC to the CPT with the default function
code assignments, FUN18, FUN19, FUN87, and FUN88 will be displayed as
TKY, MCMP, DSW, and 7SEG. The instructions, however, will be transferred
correctly.
An error will occur if any instructions not supported by the CPT are transferred
from the CPM2C.
When the program is transferred from the CPT to the PC, TKY, MCMP, DSW,
and 7SEG will be displayed on the CPT, but will not be executed in the CPU Unit.
They will be treated as NOP(00).
If expansion instructions are transferred to the PC with DM 6602 is set to the “de-
fault settings” or if instructions not supported by the CPM2C are transferred to
the PC, a message saying that expansion instructions cannot be written be-
cause DIP switch pin 4 is OFF will be displayed. Change the setting of DM 6602
to enable user settings to use expansion instructions.
It will not be possible to transfer the program if the function codes assigned to
expansion instructions (18 instructions) have been changed from their default
settings. A message to turn ON the DIP switch of the PC and execute again will
be displayed. Change the function code assignments to the CQM1 defaults
shown in the following table before programming.

There are three CPM2C instructions (SYNC(----), TIML(----), and TMHH(----)) that
are not supported by the CQM1 and cannot be used. If one of these instructions
is used in the program, an error will occur when the program is transferred from
the PC to the computer.
The input word for the frequency for PWM must be between IR 000 and IR 049,
or between IR 200 and IR 252.
If a CQM1 instruction that is not supported by the CPM2C is used in the program,
an error will occur when the program is transferred from the computer to the PC.
