Description
When positional signal is HHH or LLL, gate block
protection operates.
With built-in pull-up resistor
L: Forward
H: Reverse
L: Reset (output is non-active)
Operation/Halt operation
Also used for gate block protection
With built-in pull-down resistor
Sets 0° to 58° in 32 steps
L: Active low
