ALPHA5 smart can combine parameter settings to create the desired homing profile.
The homing profile is configured with combination of the following parameters.
(1) Starting direction for homing
Specify the starting direction (forward/reverse rotation) of homing. The direction opposite to the
homing direction after reference signal detection can be specified.
(2) Homing direction after reference signal detection
Select the side of the home position (forward or reverse rotation side) in relation to the reference
signal for homing (Deceleration starting signal) and reference signal for shift operation.
(3) Reference signal for shift operation
Select the signal serving as the direct standard of the zero position. You can select +OT or -OT.
(4) Reference signal for homing (Deceleration starting signal)
Specify the creep speed deceleration signal that is used if the encoder Z-phase is selected as a
reference signal for shift operation. You can select LS, +OT or -OT. When the encoder Z-phase
is selected, It becomes the creep speed from the start of homing operation.
