—H1 STO input 1
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.

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

Note:
The USB port can be used to upgrade the software, and the keypad port can be used to
connect an external keypad. The external keypad cannot be used when the keypad of the VFD is
used.
If input signal comes from NPN transistors, set the U-type short connector between +24V and PW
based on the power used according to the following figure.
