p2393[0...n] Hibernation mode restart speed relative w/o techn controller / Hib start w/o tec
Access level: 3 Calculated:
CALC_MOD_LIM_REF
Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: 3_1 Unit selection: p0505 Function diagram: 7038
Min:
0.000 [rpm] Max:
21000.000 [rpm] Factory setting:
0.000 [rpm]
Description: Sets the starting speed to restart the motor for the "hibernation mode" function.
When the hibernation 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 switched on 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 hibernation start speed p2390 and the relative restart
speed p2393.
Dependency: See also: p1080
Note
The parameter is set to 6 % of the nominal speed when commissioning is exited.
p2394[0...n] Hibernation mode boost time period / Hib mode t_boost
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: - Dynamic index: DDS, p0180
Unit group: - Unit selection: - Function diagram: 7038
Min:
0 [s] Max:
3599 [s] Factory setting:
0 [s]
Description: Sets the boost time period for the "hibernation mode" function.
Before the drive is finally switched off (hibernation mode), the setpoint speed is moved to the boost speed p2395 for
the time set in p2394. Depending on the application, this allows the hibernation 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
For p2394 = 0 s, the following applies:
The boost speed is not used.
p2395[0...n] Hibernation mode boost speed / Hib mode n_boost
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: p2000 Dynamic index: DDS, p0180
Unit group: 3_1 Unit selection: p0505 Function diagram: 7038
Min:
0.000 [rpm] Max:
21000.000 [rpm] Factory setting:
0.000 [rpm]
Description: Sets the boost speed for the "hibernation mode" function.
The motor is accelerated to the hibernation mode boost speed p2395 for the hibernation mode boost time period
p2394 before it is brought to a standstill via the down ramp of the setpoint channel (p1121) and subsequently switched
off (pulse inhibit).
Dependency: See also: 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.
