(3) Restart at servo OFF to ON
This section explains whether a restart is allowed or not, the setting method and
precautions in the case where servo OFF is performed once by a servo
emergency stop command during operation or by a servo OFF command during
a stop and servo ON is then performed again. (For the restarting method, refer to
section "6.5.5 Restart program".)
(a) Restart operation at servo OFF to ON
1)
Restart at servo ON after servo OFF by servo emergency stop
When operation is stopped by the servo emergency stop signal sent to
the servo amplifier, "
Md.35
Axis operation status" turns to "Error
occurrence" once, and then turns to "Servo OFF" since servo OFF is
performed automatically.
When the servo emergency stop signal to the servo amplifier turns
OFF, servo ON is performed automatically, and "
Md.35
Axis
operation status" turns to "Stop" or "Standby".
When "
Md.35
Axis operation status" is "Stop", operation can be
restarted by "
Cd.13
Restart command".
When "
Md.35
Axis operation status" is other than "Stop", a warning
"Restart not possible" (warning code: 104) occurs and the restart
command is ignored.
