Figure 4–12 Wiring diagram of control circuit
Note: If wire-passing board outlet space is insufficient when all terminals on the control board are wired, cut the knock-out hole on the lower cover for wire outlet. If a dangerous situation occurs when the knock-out hole is cut for a purpose but not wire outlet, we will not bear any responsibility.

+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 short-contact tag on the terminal before using STO function. |
