HDIB
+24V
—H1 STO input 1
1. Safe torque off (STO) redundant input, connected to the
external NC contact. When the contact opens, STO acts and the
VFD stops output;
2. Safety input signal wires use shielded wires whose length is
within 25m;
3. The H1 and H2 terminals are short connected to +24V by
default. Remove the short connectors from the terminals before
using STO function.
