l
Sinks current to ground (Logic "0") when not in limit
l
High impedance (Logic "1") when in limit
l
Requires external pull-up to +5 V (10 kΩ recommended)
Notes:
l
If the PRO280LM is driven beyond the electrical limit, it will encounter a mechanical stop. Impacting the mechanical stop could
cause damage to the stage even at low speeds.
l
Hall effect, encoder, and limit switch 5 VDC supplies are connected by the wiring system of the stage.
