Page 7: Sto Connection
XtrapulsPac™ "Safe Torque Off" manual or a short-circuit detection device must be integrated. Take care that, as the STO function performs the motor power removal without shutting down the power supply, electrical risks are remaining when the STO function is active or inactive. In applications with vertical axes, additional measures (mechanical brake) may be necessary. - Page 8 XtrapulsPac™ "Safe Torque Off" manual If the monitoring part detects incoherences between channel 1 and 2, it locks both channels in the safe state. The STO fault cannot be reset. This state can only be exited by shutting down the 24V power supply. At this moment, the user must find and solve the problem that caused this fault state.
