1st Click button and select ‘Nomal’.
2nd Click button to execute the home search operation.
3rd When the operation is executed, the motor operates in the direction set in the
parameter ‘Home Search Direction’.
4th Operation starts according to the start speed set in the parameter ‘Home Search
Start Speed’, and acceleration starts according to the acceleration time set in the
parameter ‘Home Search Acceleration Time’.
5th The constant speed operation is performed until a signal is input to the origin
sensor ‘ORG’, when the maximum speed set in the parameter ‘Home Search Max
Speed’ is reached.
6th If a signal is input to the limit sensor (±Limit) before the signal is input to the
origin sensor ‘ORG’, after the deceleration stop, it operates in the opposite
direction to find the origin.
7th When a signal is input to the origin sensor ‘ORG’, the motor decelerates and stops
according to the deceleration time set in the parameter ‘Home Search Deceleration
Time’.
8th After stop, it moves to the opposite diretion as far as the distance past the origin
sensor at the start speed set in the parameter ‘Home Search Start Speed’
to find
the origin sensor and stops.
9th When the origin found, the operation completion signal (In-Position) is output and
the In-Position indicator lights to indicate the status.
 If a value other than 0 is set in the parameter ‘Home Search Offset’, it moves to the set
position value after finding the home and outputs the operation completion signal (In-
Position) and lights up in the In-Position indicator to display the status.
 If a value other than 0 is set in the parameter ‘Home Search Position Set’, the position
specified after finding the home is set to the set value other than 0.
 In normal home search mode, Home search mode error alarm (
EH
) occurs if the ORG
signal does not input until it reaches the opposite limit sensor past the limit sensor
(±Limit).
