Zeroing by the data set method

Downloaded from ManualsNet.com
(1) Data set method
The data set method is a zeroing method which does not use the proximity
dogs. This method can be used with the absolute position system.
(2) Zeroing by the data set method
The address present value becomes the home position address when the
zeroing operation is run with the DSFRP instruction.

(3) Executing zeroing
To execute zeroing, use the servo program described in Section 7.21.5.
(4) Cautions
(a) A zero point must be passed between turning on the power and executing
zeroing.
A no zero point passed error occurs if zeroing is executed before a zero
point is passed.
After a no zero point passed error occurs, reset the error and turn the
servomotor at least one revolution using JOG operation before running the
zeroing operation again.
Use the zero point passed signal (M1606+20n) to check that a zero point is
passed.
(b) Starting zeroing with the data set method when not using the absolute
position system has the same function as the current value change
command.
(c) The zeroing data required for the data set method are the zeroing method
and home position address.

The address when the zeroing
is run is registered as the home
position address.
