SLVC / VC 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
SLVC/VC-Restrictions:
- SLVC / VC is dependent on the accuracy of the motor model being used and the measurements being
performed by the inverter. There are therefore certain restrictions on the use of SLVC / VC:

Recommended means of SLVC/VC-commissioning:
- For correct operation under SLVC / VC control it is imperative that the name plate data of the motor
(P0304 - P0310) is correctly entered and that the motor data identification (P1910) must be carried out
on a cold motor. It is also necessary to ensure that the motor ambient temperature is correctly entered
in P0625 if this is significantly different from the default value of 20°C. This must be done after the quick
commissioning has been completed (P3900) but before the motor data identification measurements are
carried out.
- See parameter P0400 and documentation of encoder and encoder module when commissioning VC
(P1300 = 21 or 23).
SLVC/VC-Optimisation:
The following parameters can be adjusted by the user to improve performance.
- P0003 = 3
- P0342: Total / motor inertia ratio
Sensorless Vector Control (SLVC):
- P1470: P gain (SLVC)
- P1472: I term (SLVC)
- P1610: Continuous torque boost (SLVC, open loop boost)
- P1611: Acceleration torque boost (SLVC, open loop boost)
- P1750: Control word of motor model
- P1755: Start-frequency motor model (SLVC)
