Explanation of I/O signals
HOMES input
This is an input signal from the HOME sensor. The mechanical home position is detected when using 3-sensor mode
return-to-home operation. See p.39 for return-to-home operation.
SLIT input
Connect when detecting the home position using a slit disk etc. When detecting the home, use of the SLIT input in
addition to the HOMES will increase the accuracy of home detection.
See p.39 for return-to-home operation.

Output signals
The driver outputs signals in the photocoupler/open-collector output mode or line driver output mode. The signal
state represents the "ON: Carrying current" or "OFF: Not carrying current" state of the internal photocoupler rather
than the voltage level of the signal.

ALM output
When an alarm generates, the ALM output will turn OFF. At the same time, the ALM LED of the driver will blink
and the motor current will be cut off and stop. The ALM output is normally closed.
See p.117 for alarm descriptions.

error alarm
Description
Sets the alarm signal status: When the positioning
operation is started while the position origin has
not been set, selects whether the alarm generates
or not.
Sets the condition in which a communication
timeout occurs in RS-485 communication.
Sets the condition in which a RS-485
communication error alarm generates. A
communication error alarm generates after a
RS-485 communication error has occurred by the
number of times set here.
