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)
