Page 10: Q957 Fault Reaction Function
Initial status: The drive is in operation and the motor is at a standstill. Step Operation The user activates Prevention of unexpected start-up by switching off the POUS switch [Sxx]. The POUS safety relay [A65] trips and the relay switches off the Safe torque off (STO) control signals on the drive control board [A41]. -
Page 11: Hardware Settings
Hardware settings Appropriate hardware settings have been preset at the factory for the safety function. The reset is preset to manual. Use the switch (1) to change settings between automatic reset (2) and manual reset (3). Power cycle (power off and on) the safety relay when a setting has been changed. -
Page 12: Q957 Start-Up And Acceptance Test
+Q957 Start-up and acceptance test You need the Drive composer PC tool or a control panel to perform the start-up and acceptance test. Initial status: Make sure that the drive is ready for use, that is, you have done the tasks of the drive start-up procedure. -
Page 13: Use Of The Safety Function
Use of the safety function Activating 1. Lock the POUS key switch. The switch locks in “ON” (open) position. Resetting 1. Unlock the POUS switch until it releases. 2. Push the POUS reset button [S7x] (if installed). The indication lamp [P7x] goes out, the POUS deactivates. -
