STO/SBC

  • Menu: 4.9.21

Description

If the STO safety sub-function is activated, the inverter no longer supplies power to the motor. As a result, the drive cannot generate any torque. This safety sub-function corresponds to a non-controlled stop according to EN 60204‑1, stop category 0. The motor coasts to a standstill or is stopped mechanically. If possible, however, you should preferably select the controlled stopping of the motor.

The STO safety sub-function can be activated as follows:

  • Via a safe digital input F‑DI
  • Via the safe process data of the higher-level safety controller

The brake is controlled with the SBC safety sub-function.
