1) Alarm signal *ALM is set to ON in the normal status but turned OFF at the occurrence of an
alarm at a level equal to or higher than the operation release level.
2) Turning reset signal RES ON under occurrence of an alarm at the operation release level
allows the alarm
(Note 1)
to be released. The action is taken at the rising edge (ON edge).
3) The alarm reset should be done after the cause of the alarm is confirmed and removed. If
alarm reset and restart are repeated many times without removal of the cause, a severe
failure such as motor burnout may occur.
(Note 1) Check the 6.4 Alarm List for details of alarms.

Ŷ Control method
Pause is possible during movement. In addition, the remaining moving distance can be
cancelled to interrupt the operation.
The pause signal is an input signal always set to ON. So, it is normally used to remain ON. Use
this function for interlock in case where an object is invaded into the moving direction of the
actuator being moved.
1) If pause signal *STP is turned OFF during operation of the actuator, the actuator is
decelerated to a stop. The deceleration is defined by the value set in the position table.
2) If pause signal *STP is returned to ON, the actuator continues the remaining movement. The
acceleration is the value set in the position table.
3) Turning reset signal RES ON during pause (*STP being ON) allows the remaining
movement to be canceled to interrupt the operation.
Caution: At occurrence of an alarm in the release level
(Note 1)
, RES can reset the alarm.
Confirm that no alarm is issued when cancelling the remaining movement.
(Note 1) Check the 6.4 Alarm List for details of alarms.
