Implementing the emergency stop functionThe drive can be equipped with emergency stop function of stop category 0. For safetyreasons, install the emergency stop devices at each operator control station and at otheroperating stations where emergency stop can be needed.Note:Pressing the stop key on the control panel of the drive, or turning the operating switch ofthe drive from position "1" to "0" does not generate an emergency stop of the motor orseparate the drive from dangerous potential.See the user’s manual for the wiring, start-up and operation instructions.Manual code (English)User’s manualOptioncode3AXD50000171828Emergency stop, stop category 0 (option +Q951) for ACS580-07,ACH580-07 and ACQ580-07 drives user's manual+Q9513AXD50000171835Emergency Stop, Category 0 (option +Q963) without opening maincontactor with safety relay for ACS580-07, ACH580-07 and ACQ580-07 drives user's manual+Q963Implementing ATEX-certified thermistor protectionSee CPTC-02 ATEX-certified thermistor protection module, Ex II (2) GD (+L537+Q971)user's manual (3AXD50000030058 [English]).Implementing the Safe torque off functionSee chapter Safe torque off function (page 221).Implementing the Power-loss ride-through functionImplement the power-loss ride-through function as follows:• Check that the power-loss ride-through function of the drive is enabled with parameter30.31 Undervoltage control.• Set parameter 21.01 Vector start mode to Automatic (in vector mode) or parameter21.19 Scalar start mode to Automatic (in scalar mode) to make flying start (startinginto 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 youare 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 tripson undervoltage, it must be reset and started again to continue operation. If the power-losssituation lasts so long that the buffering module (C22) empties, the main contactor remainsopen and the drive operates only after reset and a new start.Guidelines for planning the electrical installation 67
