r1078 CO: Total setpoint effective / Total setpoint eff
Access level: 3 Calculated: - Data type: FloatingPoint32
Can be changed: - Scaling: p2000 Dynamic index: -
Unit group: 3_1 Unit selection: p0505 Function diagram: 3030
Min:
- [rpm]
Max:
- [rpm]
Factory setting:
- [rpm]
Description: Displays the total effective setpoint.
The value indicates the sum of the effective main setpoint and supplementary setpoint.
Note
If the fixed speed setpoint is the source for the speed setpoint, then when the extended service mode is activated
(r3889.0 = 1) fixed speed setpoint 15 is displayed.
p1080[0...n] Minimum speed / n_min
Access level: 1 Calculated: - Data type: FloatingPoint32
Can be changed: C2(1), T Scaling: - Dynamic index: DDS, p0180
Unit group: 3_1 Unit selection: p0505 Function diagram: 3050, 8022
Min:
0.000 [rpm]
Max:
19500.000 [rpm]
Factory setting:
0.000 [rpm]
Description: Sets the lowest possible motor speed.
This value is not undershot in operation.
Dependency: See also: p1106
WARNING
The minimum speed is preassigned to 20% of the rated motor speed.
After all of the enable signal have been switched on, with the appropriate direction specified, the motor accelerates to
this minimum speed.
NOTICE
The effective minimum speed is formed from p1080 and p1106.
Note
The parameter value applies for both motor directions.
In exceptional cases, the motor can operate below this value (e.g. when reversing).
p1081 Maximum speed scaling / n_max scal
Access level: 2 Calculated: - Data type: FloatingPoint32
Can be changed: T, U Scaling: PERCENT Dynamic index: -
Unit group: - Unit selection: - Function diagram: 3050, 3095
Min:
100.00 [%]
Max:
105.00 [%]
Factory setting:
100.00 [%]
Description: Sets the scaling for the maximum speed (p1082).
For a higher-level speed control, this scaling allows the maximum speed to be briefly exceeded.
Dependency: See also: p1082
NOTICE
Continuous operation above a scaling of 100 % is not permitted.
