2.2 List of parameters
Description: Sets the delay time to switch back to converter operation for a non-synchronized bypass.
Dependency: The "Bypass" function is only available for induction motors.
Description: Sets the delay time for switching to line operation for a non-synchronized bypass.
Dependency: The "Bypass" function is only available for induction motors.
Description: Sets the speed threshold to activate the bypass.
Dependency: The "Bypass" function is only available for induction motors.
If the drive setpoint speed is entered via a motorized potentiometer, then the configuration bit p1030.4 should be set
in order to ensure the bypass via speed threshold function.
Note: When selecting p1260 = 3 and p1267.1 = 1, the bypass is automatically activated when this speed is reached.
The bypass speed threshold is only effective for positive directions of rotation. If the drive connected to the line
supply requires negative speeds, then this can be achieved using p1820 (direction of rotation reversal).
Description: Sets the signal source for the control command to the bypass.
Dependency: The "Bypass" function is only available for induction motors.
Description: Sets the cause that should initiate the bypass.
Dependency: The "Bypass" function is only available for induction motors.
