Max. input frequency: 50kHz;
Duty ratio: 30%–70%;
Supports quadrature encoder input; equipped with speed-measurement function
+24V—H1 STO input 1 • Safe torque off (STO) redundant input, connect to external NC
contact, STO acts when the contact opens, and the VFD stops
output;
• Safety input signal wires use shielded wire whose length is within
25m;
• H1 and H2 terminals are short connected to +24V by default; it is
required to remove the short-contact tag on the terminal before
using STO function.

Note: As shown in Fig 4.22, 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-contact tag b24V and PW
based on the power used according to the figure below.
