Figure 3-46
2. Built-in 24V power wiring
⚫ Remove the short-circuit of S24V-STO1-STO2.
⚫ As shown in the figure below, the ESTOP switch must be closed in normal situation so the
drive can output normally.
⚫ In STO mode, the ESTOP switch is turned ON, the drive stops output, and the keypad
displays STO.
⚫ With this connection, the SCM does not need to be wired (empty connection). Connect 24V
Safety dedicated power terminal, do NOT use the general +24V terminal power supply.
