Terminal
Description
HDIA
In addition to S1–S4 functions, the terminals can also act as high frequency pulse
input channels.
Max. input frequency: 50kHz
Duty ratio: 30%– 70%
Supporting quadrature encoder input; with the speed measurement function
HDIB
+24V—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.

Note: As shown in the Figure 4-19, 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 local VFD keypad is used.
If input signal comes from NPN transistors, set the U-type short-contact tag between +24V and PW
based on the power used according to the following figure.
