Allen-Bradley PowerFlex 7000 medium-voltage drives

Allen-Bradley PowerFlex 7000 medium-voltage drives offer a safe torque-off option to help industrial manufacturers and equipment builders simplify their functional safety design and meet the demands of international safety standards. Safe torque-off technology allows users to reliably remove power from the motor without removing power to the drive, enabling a faster restart of the system after a safe state is reached.

When a safe torque-off command is issued in the drive, from a user or a demand on the functional safety system, the drive immediately removes rotational power to the motor, ceasing the process. The drive stays powered and reliably monitors this safe state, ensuring no unintended operation of the motor is possible.

Suitable for industrial applications, such as material-handling conveyors and grinding mills, the drive with safe torque off is TÜV certified. It is also certified to SIL 3 of IEC 6150, and PLe, Category 3 of ISO 13849-1, the highest levels achievable for drives.
