CAUTION
When setting the parameter (#6449/bit6,7) not to check the overheat, the control unit and
the communication terminal may not be controlled because of overheat.
In such case, axis runaway may cause a machine breakage, an accident resulting in injury
or death, or device breakage.
To prevent the serious results, ordinarily set the parameters so that the overheat check is
valid.

Item
This is the bit type parameter used in the
PLC program (ladder).
Even if the data is set in the R register
that corresponds to the PLC side when
this parameter is displayed‚ the screen
will not change. Enter a different screen
once‚ and then select this screen again.
Note that some parameters have limited
uses.
Reserved for the system.
Used for only C64T.
Designate whether to detect the
communication terminal overheat alarm
or not.
0: Detects the overheat alarm.
1: Does not detect the overheat alarm.
Designate whether to detect the control
unit overheat alarm or not.
0: Detects the overheat alarm.
1: Does not detect the overheat alarm.
Designate whether to use the macro
interface for respective part systems or
not.
0: Conventional macro interface
common to part systems.
1: Available to respective part systems.
bit0: High-speed input from R54.
bit1: High-speed input from R55.
Note that this is used for only C64T.
bit0: High-speed output to R56
bit1: High-speed output to R57
Note that this is used for only C64T.
