bit 2 : Return-to-origin operation overtravel operation selection 0: Reversal by overtravel detec-
tion, 1: Stop by overtravel detection
This bit defines whether to stop or reverse operation when an overtravel is detected be-
fore ORL (origin search limit signal) is detected.
bit 3 : Origin limit switch timing selection 0: ON edge detection, 1: OFF edge detection
This bit defines whether or not to detect the limit switch at its ON edge or OFF edge.
The figure below shows action according to the setting of the 3037Hex-0AHex parameter. In the
figure, it is assumed that bit 2 = 0 and reverse operation is performed at detection of an overtravel.
