Find reference origin diagram:
Sequential diagram of finding reference origin on forward side:
Steps:
(1). Install limit switch at forward and reverse side. At the rising edge of /SPD-A, motor runs forward
at the speed of P4-01 to find the reference origin on forward side.
(2). After the working table hit the limit switch, the motor stop as the mode set by parameter P0-28
(3). Motor leaves the limit switch at the speed of P4-02. After the working table left the limit switch,
the motor run at the Z phase signal position of No.n optical encoder. This position is considered as the
coordinates origin, n is decided by parameter P4-00.
