Power to the motor is cut.
Note 1) [●] means ON, [ ] means OFF.
Note 2) The origin has been recognized when the operation is repeated, so it can operate without the
procedure item 2.
Note 3) The “OUT*” signals are reset during the rising edge of the Drive signal. The “OUT*” signal which
follows the “IN*”signal are outputted at the falling edge of the "drive" signal.
Note 4) When the alarm is generated, the alarm group is displayed.
Please confirm the controller (LEC series) manual for a detailed content of the alarm.
Note 5) Leave an interval of 15ms (the recommendation is 30ms) or more between input signals and
maintain the state of the signal for 15ms (the recommendation is 30ms) or more, because PLC
processing delays and controller scanning delays can occur.
