Specify the direction of the zero position when viewed from the reference signal for shift operation. The
reference signal for shift operation is passed during home position shift unit amount travel in this
direction.
If +OT or -OT is set as a reference signal for homing (deceleration starting signal), this parameter is
disabled and the direction opposite to the one toward the specified OT signal is the homing direction
after reference signal detection. If the encoder Z-phase is set as a reference signal for homing, this
parameter is disabled and the direction follows Starting direction for homing.
The definition of the direction of motion is shown below.
Forward: direction of position increase Reverse: direction of position decrease

Specify the signal serving as a standard of the home position.
The position of a travel from the specified reference signal toward the homing direction after reference
signal detection by the home position shift unit amount is the home position.
The home position accuracy (reproducibility of zero position) is the highest with 1 (encoder Z-phase).
If the Z-phase is selected, the reference signal for shift operation (deceleration starting signal) can be
installed.
Next to the encoder Z-phase, 4 (interrupt input) has the highest home position accuracy (reproducibility
of zero position). This is because 4 (interrupt input) detects the interrupt position with a signal while 0
(home position LS), 2 (+OT) and 3 (-OT) detects a level.
If one among 0 (home position LS), 2 (+OT) and 3 (-OT) is selected, there is an error of ±250 pulses
in the zero position at a creep speed for homing of 50 r/min.
In the case of GYB motor, the Z phase of encoder will be detected right after the power is turned
on.For homing operation, the motor should be kept over 372-degree at the speed of 100r/min.The Z
phase can not be correctly detected if this condition is not satisfied.
