Sourcetronic ST600 - Input;Output Signal Connection Diagram

Frequency Inverter ST600 Series High-Performance Multifunction VFD Installation Guide
-37-
HDIB
Max. input frequency: 50kHz;
Duty ratio: 30%–70%;
Supports the input of a quadrature encoder with 24V power supply; equipped with speed-
measurement function
+24V—H1
STO input 1
1. Safe torque off (STO) redundant input, connect to external NC
contact, STO acts when the contact opens, and the VFD stops output;
2. Safety input signal wires use shielded wire whose length is within
25m;
3. H1 and H2 terminals are short connected to +24V by default; it is
required to remove the jumper on the terminal before using STO
function.

Set NPN/PNP mode and internal/external power via U-shaped jumper. PNP internal mode is adopted
by default.
