Description
When positional signal is HHH or LLL, gate block protection operates.
With built-in pull-up resistor, built-in digital filter ( ≈ 500 ns)
L: Forward
H: Reverse
L: Reset (output is non-active)
operation/halt operation, also used for gate protection,
built-in pull-up resistor
With built-in pull-down resistor
I
Connect the peak-hold capacitor and discharge resistor to GND, parallel
to each other
Connect the low-pass filter capacitor (built-in 100 kΩ resistor)
Sets 0° to 58° in 32 steps
Set lower limit for LA (LL = 0 V to 5.0 V)
Set upper limit for LA (UL = 0 V to 5.0 V)
L: Active LOW
H: Active HIGH
Inputs DC link current.
Reference voltage: 0.5 V
With built-in filter ( ≈ 1 µs), built-in digital filter ( ≈ 1 µs)
With built-in feedback resistor
5 V (typ.), 30 mA (max)
Outputs 3 PPR of positional signal
Detects reverse rotation.
Select active HIGH or active LOW using the output logic select pin.
