You can select the NPN/PNP mode and internal/external power through the U-type short
connector. NPN internal mode is adopted by default.
Internal impedance: 3.3kΩ

functions of which be set through function codes
24V-power
Safe torque off (STO) redundant input, connected to the

external NC contact. When the contact opens, STO acts
and the VFD stops output;
Safety input signal wires use shielded wires whose length

is within 25m;
The H1 and H2 terminals are short connected to +24V by

default. Remove the short connectors from the terminals
before using STO function.
