2.4. Safe Torque Off Input (STO)

IMPORTANT: The safety components (STO) certification is pending for the iXC2.

The STO circuit is comprised of two identical channels, each of which must be energized in order for
the drive to produce motion. Each STO input is opto-isolated and accepts 24 V levels directly without
the need for external current limiting resistors.

IMPORTANT

: The drive might be equipped with an STO bypass circuit board. The

bypass circuit board defeats the STO safety circuit and allows the system to run at all
times. To use the STO safety functionality, remove the circuit board and make
connections as outlined in this section.

IMPORTANT

: The application circuit and its suitability for the desired safety level is the

sole responsibility of the user of the drive.

WARNING

: STO wires must be insulated to prevent short circuits between connector

pins. The primary concern is a short circuit between STO 1 IN and STO 2 IN wire
strands.
