2.2 List of parameters
Description: Sets the boost speed for the energy-saving mode function.
The motor is accelerated to the energy-saving mode boost speed p2395 for the energy-saving mode boost time
period p2394 before it is brought to a standstill via the down ramp of the setpoint channel (p1121) and subsequently
powered down (pulse inhibit).
Dependency: Refer to: p2394
Caution: The controller is not operational while the boost speed is being impressed. As a result, for example, for pump
applications, it must be ensured that the tank does not overflow as a result of the additional boost. For compressors,
it must be ensured that the boost speed does not result in an overpressure condition.
Description: Sets the maximum shutdown time for the energy-saving mode function.
If the drive is in the energy-saving mode (pulse inhibit) then it is powered up again at the latest after the maximum
power-down time has expired. If the restart conditions are fulfilled earlier, then the drive is correspondingly powered
up earlier.
Danger: The drive automatically powers itself up at the latest after the maximum power-down time has expired.
Caution: Once the maximum shutdown time has expired, the drive switches itself on automatically and accelerates to the start
speed. The technology controller only becomes effective again when this speed is reached (for p2398 = 1).
Depending on the application, e.g. for pumps, it should be ensured that as a result of cyclic starts the tank does not
overflow or for compressors, an overpressure condition does not occur.
Note: Automatic restart once the maximum OFF time has elapsed is de-activated by setting p2396 = 0 s.
Description: Displays the actual output speed for the energy-saving mode function.
Note: Zero is displayed if the boost or starting speed is not active.
Description: Sets the operating mode for the energy-saving mode function.
Value: 0: Energy-saving mode inhibited
1: Energy-saving mode activated
Dependency: Refer to: p2200, p2251
