Internal input circuit
Memo The signal state indicates the “ON: current supplied” or “OFF: current not supplied” state
of the internal photocoupler rather than the voltage level of the signal.

END input
This terminal is used to input the END signal output from the driver at the end of operation. This
terminal should be connected when using the
or servo motor.
The END signal is enabled or disabled via command input. (Set to “enabled” at the time of power on.)
•
TIM. input
This terminal is used to input the timing signal from the driver.
When mechanical home is detected in mechanical home seeking mode, an accurate home position can be
found by using this signal with the HOMELS input or the HOMELS input/SLIT input by connecting
them with an AND logic operator.
•
ALM input
This terminal is used to input the alarm signal from the driver. (The driver’s alarm outputs may either be
at normally open or normally close, depending on the model.)
If an alarm-signal input is fed while the motor is in operation, the motor will decelerate to a stop and the
sequence program will stop also.
No pulse can be output while alarm signal inputs are being fed, although any command not associated
with pulse output can be executed.
The input logic may be switched between normally open and normally close via command inputs. (Set to
“normally close” at the time of power on.)
•
+LS and -LS inputs
This terminal is used to input signals from +LS and -LS.
If the LS input is turned on during pulse output, the motor will stop immediately. However, mechanical
home seeking will continue even if the LS input is turned on.
The input logic may be switched between normally open and normally close via command inputs. (Set to
“normally open” at the time of power on.)
Note
Note that two different input logics cannot be set for the +LS and -LS inputs,
respectively.
•
HOMELS input
This terminal is used to input signals from HOMELS when performing high-speed home seeking using
3-sensors.
The input logic may be switched between normally open and normally close via command inputs. (Set to
“normally open” at the time of power on.)
