HIGH–SPEED RESPONSE FUNCTION
By executing a program, which is compiled in the normal mode
beforehand, in the high–speed response mode, axis start and stop
operations can be executed faster than conventionally done.
In the descriptions below, a program compiled beforehand is referred to
as a motion program.
1) Features of the high–speed response function
In the high–speed response mode, start signal monitoring is performed
at shorter intervals than in the normal mode. So, axis start and stop
operations in response to an input signal from an external source can
be made faster than in the normal mode.
2) High–speed response mode and normal mode
With a system that uses the high–speed response mode, the mode must
be switched between the high–speed response mode and normal mode
according to the function used.
High–speed response mode
This mode is used to execute a motion program by using the
high–speed response function.
Axis start and stop operations can be performed faster than in the
normal mode.
Unlike a conventional system, operations such as automatic
operation, manual operation, and reference position return
operation cannot be performed.
Parameters cannot be rewritten.
Normal mode
This mode allows operations such as automatic operation, manual
operation, and reference position return operation to be performed
in the same way as when a conventional system is used.
The execution of a motion program using the high–speed response
function is disabled.
NOTE
1 In the high–speed response mode, parameters cannot be
rewritten through the MDI and PMC window. If an attempt
is made to rewrite parameters through the MDI, the warning
message ”Invalid mode” is output. If an attempt is made to
rewrite parameters through the PMC window, the complete
code 7 is output.
2 Before executing a motion program, be sure to establish a
reference position in the normal mode.
