Implementing the emergency stop function

The drive can be equipped with emergency stop function of stop category 0. For safety
reasons, install the emergency stop devices at each operator control station and at other
operating stations where emergency stop can be needed.
Note:
Pressing the stop key on the control panel of the drive, or turning the operating switch of
the drive from position "1" to "0" does not generate an emergency stop of the motor or
separate the drive from dangerous potential.
See the user's manual for the wiring, start-up and operation instructions.

Implementing ATEX-certified thermistor protection

Implementing the Safe torque off function

See chapter Safe torque off function (page

Implementing the Power-loss ride-through function

Implement the power-loss ride-through function as follows:
• Check that the power-loss ride-through function of the drive is enabled with parameter
30.31 Undervoltage control.
• Set parameter 21.01 Vector start mode to Automatic (in vector mode) or parameter
21.19 Scalar start mode to Automatic (in scalar mode) to make flying start (starting
into a rotating motor) possible. If the installation is equipped with a main contactor,
prevent its tripping at the input power break. For example, use a time delay relay (hold)
in the contactor control circuit.
WARNING!
Make sure that the flying restart of the motor will not cause any danger. If you
are in doubt, do not implement the Power-loss ride-through function.

Units with line contactor (option +F250)

The main contactor of the drive opens in a power-loss situation. When the power returns,
the contactor closes. However, if the power-loss situation lasts so long that the drive trips
on undervoltage, it must be reset and started again to continue operation. If the power-loss
situation lasts so long that the buffering module (C22) empties, the main contactor remains
open and the drive operates only after reset and a new start.
