Description: Sets the delay time for the energy-saving mode function.
To ensure that the drive can be shut down (pulse inhibit), a restart condition must not occur during this time.
Dependency: Refer to: p2390, p2392, p2393
Description: Sets the motor restart time for the energy-saving mode function.
If the energy-saving mode function is active, the technology controller continues to operate and supplies a speed
setpoint to the setpoint channel. Since the drive is de-activated, there is no system deviation at the input of the
technology controller. As soon as this exceeds the restart value p2392, the drive is automatically powered up and the
speed is controlled to 1.05 * (p1080 + p2390) via the up ramp of the setpoint channel.
Note: The restart value is set to 5 % when commissioning is completed.
Description: Sets the start speed to restart the motor for the energy-saving mode function.
When the energy-saving mode is active, a speed setpoint is still supplied to the setpoint channel. If the setpoint
increases again and in so doing exceeds the restart speed, the drive is automatically powered up and the speed
setpoint is controlled to p1080 + p2390 + p2393 via the up ramp of the setpoint channel.
The restart speed is the sum of the minimum speed p1080, the energy-saving mode start speed p2390 and the
relative restart speed p2393.
Dependency: Refer to: p1080
Note: The parameter is set to 6 % of the nominal speed when commissioning is exited.
Description: Sets the boost time period for the energy-saving mode function.
Before the drive is finally powered down (energy-saving mode), the setpoint speed is changed to the boost speed
p2395 for the time set in p2394. Depending on the application, this allows the energy-saving mode intervals to be
extended (in time).
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.
Note: If a boost speed is not approached, then the boost time period is set to 0 s.
