6. DRIVE MODULE
6 − 19
POINT
The sequence program features an interlock function which prevents the for-
ward (M4802+20n) and reverse (M4803+20n) JOG start commands from
being switched ON simultaneously.
(d) Completed signal OFF command (M4804+20n)
This command is used to switch the "positioning START completed signal"
(M4000+20n) and the "positioning completed signal" (M4001+20n) OFF in
the sequence program.

POINT
Do not switch the "completed signal OFF command" ON by a PLS instruction.
Such an action will make it impossible to switch the "positioning START
completed signal"(M4000+20n) and the "positioning completed signal"
(M4001+20n) OFF.
(e) Error reset command (M4807+20n)
1) The error reset command is used to clear the minor or major error code
storage area of the virtual servo motor for which an error has been
detected and to reset the error detection signal.
2) The following processing is carried out when the error reset command
comes ON.
• If the virtual servo motor and output module are normal the minor and
major error code storage areas are cleared and the error detection
signal is reset.
• If the virtual servo motor and output module error has not been
canceled, the error code is again stored in the minor/major error code
storage area.
In this case the error detection signal (M4007+20n) remains ON.
POINT
Do not turn the error reset command (M4807+20n) ON using the PLS
command.
If it is set to ON using the PLS command it may not be possible to carry out
error reset.
