Sensorless vector control (SLVC)
Control mode | 0 |
20
SLVC can provide excellent performance for the following types of application:
•Applications which require high torque performance
•Applications which require fast respond to shock loading
•Applications which require torque holding while passing through 0 Hz
•Applications which require very accurate speed holding
•Applications which require motor pull out protection
Filter time for act. freq (SLVC) | 4 ms |
Sets time constant of PT1 filter to filter the frequency deviation of speed controller in operation mode SLVC (sensorless vector control).
Decreasing the value leads to a higher dynamic of the speed regulation. Instability is seen if the value is to low (or to high). p1452 = 2 can be set for most applications.
Gain speed controller (SLVC) | 3.0 |
Enters gain of speed controller for sensorless vector control (SLVC).
Integral time | 400 ms |
Enters integral time of speed controller for sensorless vector control (SLVC).

Continuous torque boost (SLVC) |
|
| 50.0 % | |
Sets continuous torque boost in lower frequency range of SLVC (sensorless vector control). Value is entered in [%] relative to rated motor torque r0333.

Acc. torque boost (SLVC) | 0.0 % |
Sets acceleration torque boost in lower frequency range of SLVC (sensorless vector control). Value is entered in [%] relative to rated motor torque r0333.
p1611 is only effective in the
In opposite to p1610 the acceleration torque boost p1611 is only in operation during acceleration/deceleration.
