hi,
i'm gona use a mm440 for a lift application.
i set the p0700 to 2 for activating the digital inputs for speed selection and direction selection.
i used digin1 for lift up so i set the p701 to 16 (direct selection and start) but how can i connect emergency stop input on mm440?
what happens if i set p701 to 15 (direct selection but not start) and use an other dig. input for start / off1 (by setting it to 1)

i mean does an error occur if i give 24v to the start input but do not give any signal to the direct selection inputs?

finally what is the correct circuit for mm440 with an emergency stop button? how can i connect the em.stop inputs to the inverter?
