[Classification] Output signal
[Function] This signal informs the PMC of the input status of the high-speed skip signal.
[Output condition] 1: When the contact of high-speed skip signal is close.(The input voltage is at a low level.)
0: When the contact of high-speed skip signal is open.(The input voltage is at a high level.)
Absolute maximum rating
Input voltage range Vin: −3.6 to +13.6V

- Page 2Outline In the high speed skip function of Series 30i/31i/32i, please pay attention to the connection of the skip signal line. Because the contact state is different from Series 15i/16i/18i/21i/0i when the CNC recognizes the input of skip signal. Series 30i/31i/32i : The skip signal is assumed to be
