Origin Search Operation

6-4-2 Details of Parameters

Operation Mode
Operation mode p
Origin input signal
(selected using the
method parameter)
Origin is determined
0
by detecting the rising
edge of the origin
input signal.

3 The origin is detected
at the drive using the
servo drive's origin
adjustment function.
The origin input signal
at the PCU is not
used. Mode 3 cannot
be used with drives
that do not have the
origin adjustment
function.
Note Specify mode 3 when using the origin adjustment function of OMRON's R88D-H or R88D-M Servo Motor
Drive.
4. Origin search direction:
Set the direction for origin search.
5. Origin compensation data:
If fine adjustment is required after the origin has been determined (e.g., if
there is inaccuracy in the position at which the proximity sensor turns ON or
if the motor has been changed), set the amount of compensation (the origin
compensation value) required.
Note There are drives for stepping motors that can output positioning com-
pleted signals in the same way as servo drives. It is possible to set
modes 1 or 2 if this kind of drive is used.
The settings for the 5 parameters that determine the operation pattern for origin
search are given here. For data configurations for each of the parameters, refer
to 4-3 Axis Parameter Area.
The origin mode parameters determined the I/O signals used for origin search.
The I/O signals used for each mode are given in the following table.
I/O signals
Error counter reset
origin detection
Not used.
Turns ON for 20 ms
when origin is
detected.
Used as output for the
origin adjustment
command.
Set the operation according to the drive used and the application.
Positioning
output completed input
Not used.
After the origin has
been detected, origin
search operation is
terminated.
After the origin has
been detected, origin
search operation will
not be terminated until
a positioning
completed input completed input
signal has been
received from the
drive. (The Busy Flag
will stay ON during
this time.)

Operation when p

during deceleration
from origin search
high speed
The origin input signal
during deceleration is
detected. An origin
input signal error
(error code 6202) will
be generated, and
operation will
decelerate to a stop.
The origin input signal
during deceleration is
not detected.
Operation is stopped
and the origin is
determined when the determined when the
origin input signal is
received after the
origin search
proximity speed has
been reached.
Because origin
detection is not
carried out at the
PCU, this situation
does not arise.
