Origin Search Operation Section 6-4
Note There are drivers for stepping motors that can output positioning completed
signals in the same way as Servo Drives. It is possible to set modes 1 or 2 if
this kind of driver is used.
Origin Search Operation
The following 4 modes are available for origin search operation.
The origin search operation settings are as follows:
0: Reverse mode 1
1: Reverse mode 2
2: Single-direction mode
3: Reverse mode 3
Origin Detection Method
The origin detection method specifies settings related to the origin proximity
input signal. Depending on the setting of the axis parameter, the following 4
patterns can be selected.
Driver Explanation Operation mode
Stepping motor driver 0
Servo Drive (see note) Use this mode to reduce
the operating time applica-
tions where a high degree
of positioning accuracy is
not required. (The position-
ing completed signal at the
Servo Drive is not used.) 1
Use this mode for a high
degree of positioning accu-
racy. (The positioning com-
pleted signal at the Servo
Drive is not used.) 2
Use this mode for a Servo
Drive with an origin adjust-
ment function. 3
Origin search operation Reverse modes
Reverse mode 1
Reverse mode 2
Single-direction mode
There are two patterns possible for origin search
operation: the origin search direction and the opposite
direction.
Direction reversed when input is received from
the limit signal in the origin search direction.
Operation is stopped and an error is generated
when input is received from the limit signal in the
origin search direction.
Origin search is performed in one direction only.
Reverse mode 3
Basic functions are the same as with reverse mode 2.
When the direction is reversed at the origin proximity
input signal, however, shock to mechanical systems
is reduced.
