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 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:
fmax = min(200 Hz, 5 P0310) | (max. frequency) | ||||||
| 1 | ≤ | P0305 | ≤ | r0209 | (ratio of rated motor current to rated inverter current) | |
4 | r0207 | r0207 | |||||

| |||||
no synchronuos motor
Recommended means of
-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).
